Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation and Summary of Significant Accounting Policies	Description of Business, Basis of Presentation and Summary of Significant Accounting Policies The Meet Group, Inc. (the “Company,” “The Meet Group,” “us,” or “we”) is a portfolio of mobile social entertainment apps designed to meet the universal need for human connection. We leverage a powerful live-streaming video platform, empowering our global community to forge meaningful connections. Our primary apps are MeetMe®, LOVOO®, Skout®, Tagged® and, as of March 5, 2019 , Growlr®. See Note 16— Subsequent Events for further details. We operate location-based social networks for meeting new people, primarily on mobile platforms, including on iPhone, Android, iPad and other tablets, that facilitate interactions among users and encourage users to connect, communicate and engage with each other. Over the past two years we have transformed our business from an advertising based revenue model to one where the majority of our revenue is derived from user pay monetization and subscription. The fastest growing component of user pay monetization comes from in-app purchases, including virtual gifts associated with our live video product. We began developing our video platform in 2016 with the belief that we could successfully pair live-streaming and dating – a model that we had seen work effectively for Asian dating app providers. We first launched video on MeetMe early in 2017, and, in October of 2017, we began to monetize the feature by enabling gifting within the video streams. During this time period, we also executed on our strategy of acquiring other properties: Skout, Inc. (“Skout”), Ifwe Inc. (“if(we)”) and Lovoo GmbH (“Lovoo”) – where we believed our live-streaming platform would fit naturally. We then integrated live video into each app. We launched the monetized video platform on Skout in the fourth quarter of 2017, Tagged (if(we)) in the second quarter of 2018 and Lovoo beginning in the second quarter of 2018. We have also continued to add features and enhancements intended to drive video engagement and increase monetization for all the apps. Live video has become the fastest growing revenue product in our history. We also offer online marketing capabilities, which enable marketers to display their advertisements on our apps. We offer significant scale to our advertising partners, with hundreds of millions of daily impressions across our active global user base, and sophisticated data science for effective targeting. We work with our advertisers and advertising networks to maximize the effectiveness of their campaigns by optimizing advertisement formats and placements. Just as Facebook has established itself as the social network of friends and family, and LinkedIn as the social network of colleagues and business professionals, The Meet Group is creating the social entertainment network not of the people you know, but of the people you want to know. Nimble, fast-moving and already in more than 100 countries, we are challenging the dominant player in our space, Match Group, Inc. (“Match Group”), and differentiating ourselves with live video, which is not offered by many of our direct competitors. Modeled after the video products offered by Asian dating app providers, but enhanced in order to appeal to western audiences, our live video product is aimed at the nexus of entertainment and community, where we believe our apps exhibit natural strength. Our vision extends beyond dating and entertainment. We focus on building quality products to satisfy the universal need for human connection among all people, everywhere – not just paying subscribers. We believe meeting new people is a basic human need, especially for users aged 18-34, when so many long-lasting relationships are made. We use advanced technology to engineer serendipitous connections among people who otherwise might never have met – a sort of digital coffeehouse where everyone belongs. Over the years, The Meet Group’s apps have originated untold numbers of chats, shares, good friendships, dates, romantic relationships – even marriages. We believe that we have significant growth opportunities enabled through our social entertainment platform. We believe our scale provides unique advantages to grow video monetization, while also establishing a high density of users within the geographic regions we serve. As The Meet Group’s networks grow and the number of users in a location increases, we believe that users who are seeking to meet new people will incrementally benefit from the quantity of relevant connections. Basis of Presentation The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). The consolidated financial statements include the accounts of all subsidiaries and affiliates in which the Company holds a controlling financial interest as of the date of the consolidated financial statements. The consolidated financial statements include the accounts of The Meet Group and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are required in the determination of business combinations, revenue recognition, accounting for business combinations, accounts receivable valuation, the fair value of financial instruments, the valuation of long-lived assets, valuation of deferred tax assets, income taxes, contingencies, goodwill and intangible assets, and stock-based compensation. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. The Company’s estimates often are based on complex judgments, probabilities and assumptions that it believes to be reasonable but that are inherently uncertain and unpredictable. For any given individual estimate or assumption made by the Company, there may also be other estimates or assumptions that are reasonable. The Company regularly evaluates its estimates and assumptions using historical experience and other factors, including the economic environment. As future events and their effects cannot be determined with precision, the Company’s estimates and assumptions may prove to be incomplete or inaccurate, or unanticipated events and circumstances may occur that might cause it to change those estimates and assumptions. Market conditions, such as illiquid credit markets, volatile equity markets, dramatic fluctuations in foreign currency rates and economic downturn, can increase the uncertainty already inherent in its estimates and assumptions. The Company adjusts its estimates and assumptions when facts and circumstances indicate the need for change. Those changes generally will be reflected in the Company’s consolidated financial statements on a prospective basis unless they are required to be treated retrospectively under the relevant accounting standard. It is possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. The Company is also subject to other risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in competition, litigation, legislation and regulations. Revenue Recognition The Company recognizes revenue when control of the promised good or service is transferred to the customer in an amount that the Company expects to be entitled in exchange for the good or service. User Pay Revenue User pay revenue is earned from in-app purchase products and subscriptions sold to mobile application and website users. The Company offers in-app products such as Credits, Points, Gold and Icebreakers (collectively, the “In-App Products”). Users purchase the In-App Products to exchange for the Company’s virtual products. The In-App Products allow users to engage with other users on the applications and in live video. They also put users in the spotlight, helping them get more attention from the community in order to meet more people faster. Platform users do not own the In-App Products but have a limited right to use the In-App Products on virtual products offered for sale on the Company’s platforms. In-App Products may be used to purchase virtual gifts for other users. These virtual gifts are received by other users and converted into Diamonds. Diamonds represent an intermediary currency that the Company manages. Diamonds can either be converted back into credits or may be used to claim rewards, including in some instances cash rewards. The In-App Products are not transferable, cannot be sold or exchanged outside of our platforms, are not redeemable for any sum of money, cannot be gifted to other users and can only be used on our platforms. The In-App Products are recorded in deferred revenue when purchased and recognized as revenue over time when: (i) the In-App Products are used by the customer; or (ii) the Company determines the likelihood of the In-App Products being redeemed by the customer is remote (breakage) and there is not a legal obligation to remit the unredeemed In-App Products to the relevant jurisdiction. The breakage rate is based upon Company-specific historical redemption patterns. Breakage is recognized in revenue as the In-App Products are used on a pro rata basis over a three or six -month period (life of the user) beginning at the date of the sale and are included in revenue in the condensed consolidated statements of operations and comprehensive income (loss). Breakage recognized in 2018 , 2017 and 2016 was $2.8 million , $1.5 million and $1.3 million , respectively. For MeetMe+, Tagged, Skout and Lovoo subscription-based products, the Company recognizes revenue over the term of the subscription. Under ASC 606, user pay revenue has a single performance obligation. Subscriptions provide customers with premium access to the application and include credits on MeetMe+, while In-App Product purchases are satisfied by standing ready to allow users to exchange the In-App Products for virtual products. The consideration received for these services is fixed at the time of purchase. The customer simultaneously receives and consumes the benefits of user pay features as the Company performs the services. Revenue is recorded in deferred revenue when purchased by customer and recognized as revenue over time as the performance obligation is satisfied. Advertising Revenue Advertising revenue is comprised of mobile and web advertising. Within each revenue stream, the Company has one performance obligation to publish advertisements as specified by the respective contracts. The amount of consideration that the Company expects to receive for the services is variable based on the volume of advertisement impressions. The Company does not offer any discounts or free impressions and has not historically experienced any collectability issues. The Company also recognizes revenue from cross-platform/social theater and cost-per-action (“CPA”) offers. Each of these revenue streams has one performance obligation. For cross-platform/social theater contracts, the consideration promised is fixed per ad campaign and term, and required services to be delivered. However, the monthly revenue could vary depending on the actual delivery of impressions throughout the contract term. These contracts are typically based on cost per thousand (“CPM”) rates and number of impressions served due to traffic volume and the specific ad campaign. For CPA offers, the consideration promised is variable based on a revenue share rate, and/or based on the number of actions delivered per the agreement. As such, the Company recognizes all actual advertising revenues from impressions or actions delivered on a monthly basis rather than estimating revenue at the beginning of the period. The Company has transactions with several partners that qualify for principal agent considerations. The Company recognizes revenue, net of amounts retained by the third-party partners, pursuant to revenue sharing agreements with advertising networks. The form of the agreements is such that the Company provides services in exchange for a fee. The Company determines only the fee for providing its services to advertising agencies and has no latitude in establishing prices with third party advertisers. In instances where the Company works directly with an advertiser, revenue is recognized on a gross basis. The Company is the primary obligor in arrangements made with direct advertisers, as there is no third-party facilitating or managing the sales process. The Company is solely responsible for determining price, product or service specifications, and which advertisers to use. The Company assumes all credit risk in the sales arrangements made with direct advertisers. The Company has determined that the performance obligation under the advertising revenue streams is recognized ratably over time utilizing the “Right to Invoice” practical expedient as customers simultaneously consume and receive benefits of the advertisement impressions. Deferred Revenue The Company records deferred revenue when the consideration for a good or service is received in advance of its performing the obligation. Cash and Cash Equivalents The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash and cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. Restricted Cash Restricted cash consisted primarily of two certificates of deposit that are required as security for a letter of credit in connection with two of our facilities in California. The Company no longer has leases for these facilities and, therefore, does not have any restricted cash as of December 31, 2018. The amount available under the letter of credit was $0.9 million at December 31, 2017. Accounts Receivable and Allowance for Doubtful Accounts The Company extends credit on a non-collateralized basis to both U.S. and international customers. The Company extends credit to customers in the normal course of business and maintains an allowance for doubtful accounts resulting from the inability or unwillingness of customers to make required payments. Management determines the allowance for doubtful accounts by evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. The Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. Based on this evaluation, the Company maintains an allowance for potential credit losses and for potential discounts based on historical experience and other information available to management. Discounts historically represent less than 1% of the related revenues. The fees associated with display advertising are often based on “impressions,” which are created when the ad is viewed. The amount of impressions often differs between non-standardized tracking systems, resulting in discounts on some payments. Difference between ad serving platforms with respect to impressions is primarily due to lag time between serving of advertising and other technical differences. Balance at Beginning of Period Additions, Costs and Expenses Deductions, Write-Offs Balance at End of the Period Allowance for Doubtful Accounts: Year Ended December 31, 2018 $ 527,958 $ 193,746 $ 338,125 $ 383,579 Year Ended December 31, 2017 $ 283,000 $ 304,306 $ 59,348 $ 527,958 Year Ended December 31, 2016 $ 133,000 $ 152,587 $ 2,587 $ 283,000 Business Acquisitions The Company accounts for all business acquisitions at fair value and expenses acquisition costs as they are incurred. Any identifiable assets acquired and liabilities assumed are recognized and measured at their respective fair values on the acquisition date. If information about facts and circumstances existing as of the acquisition date is incomplete at the end of the reporting period in which a business acquisition occurs, the Company will report provisional amounts for the items for which the accounting is incomplete. The measurement period ends once the Company receives sufficient information to finalize the fair values; however, the period will not exceed one year from the acquisition date. In connection with certain acquisitions, the Company enters into agreements to pay additional amounts in cash on the achievement of certain performance measures for up to 1 year ending after the acquisition date. The Company measures this contingent consideration at fair value at the acquisition date and records such contingent consideration as a liability on the Company’s Consolidated Balance Sheets on the acquisition date. The fair value of each contingent consideration liability is remeasured at each reporting period with any change in fair value recognized as income or expense within operations in the Company’s consolidated statements of operations and comprehensive income (loss). See Note 2— Acquisitions for more information on the Company’s business acquisitions. Goodwill Goodwill reflects the cost of an acquisition in excess of the fair values assigned to the identifiable net assets acquired. Goodwill is not amortized; rather, it is subject to a periodic assessment for impairment by applying a fair value based test. The Company performs its annual impairment test as of October 1st of a given calendar year, or more frequently if events or changes in circumstances indicate that the asset might be impaired. In prior years, the Company performed its annual goodwill impairment test as of December 31st of a given calendar year. This change was made to more align with the Company’s internal forecasting process. Goodwill is tested for impairment at the reporting unit level. The Company has determined that there are two reporting units, The Meet Group US and Lovoo. Accounting for acquisitions requires the Company to recognize, separately from goodwill, the assets acquired and the liabilities assumed at their acquisition-date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition-date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, the estimates are inherently uncertain and subject to refinement. The impairment model permits, and the Company utilizes, a simplified approach for determining goodwill impairment. In the first step, the Company evaluates the recoverability of goodwill by estimating the fair value of the Company’s reporting unit using multiple techniques, including an income approach using a discounted cash flow model and a market approach. Based on an equal weighting of the results of these two approaches, a conclusion of fair value is estimated. The fair value is then compared to the carrying value of the Company’s reporting unit. If the fair value of a reporting unit is less than its carrying value, the Company recognizes this amount as an impairment loss. Impairment losses, limited to the carrying value of goodwill, represent the excess of the carrying amount of goodwill over its implied fair value. In the fourth quarter of 2017, through the Company’s annual testing of goodwill, the Company determined that a $56.4 million one-time, non-cash impairment was required for our U.S. reporting unit, due predominantly to the market-driven impacts on advertising revenue resulting from lower CPMs which negatively affected the Company’s results and outlook. We believe this non-cash impairment charge does not impact the Company’s ability to generate cash flow in the future; it is not tax deductible. There was no goodwill impairment noted in our annual impairment testing for 2018. See Note 4— Goodwill in the accompanying notes to the consolidated financial statements for further details on our annual impairment testing. Intangible Assets Intangible assets consist of acquired trademarks, domain names, advertising customer relationships and mobile applications and are initially recorded at fair value. Amortization is recorded using an accelerated method based on projected revenues related to each asset over the respective estimated useful lives. Years Trademarks 5 to 10 Domain names 5 to 10 Mobile applications, purchased and internally developed 1 to 5 Customer relationships 1 to 10 Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Property and equipment acquired in business combinations is stated at fair value. The cost of improvements that extend the life of property and equipment are capitalized. All ordinary repair and maintenance costs are expensed as incurred. When capitalized assets are retired or sold, the cost and related accumulated depreciation or amortization is removed from the accounts, with any gain or loss reflected in operations. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows: Years Servers, computer equipment and software 1 to 3 Office furniture and equipment 3 to 5 Leasehold improvements 1 to 10 Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful life of the improvement or the lease term. Long-Lived Assets and Intangibles with Finite Lives Property and equipment and amortizable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an analysis is necessitated by the occurrence of a triggering event, then the Company compares the carrying amount of the asset with the estimated future undiscounted cash flows expected to result from the use of the asset. If the carrying amount of the asset exceeds the estimated expected undiscounted future cash flows, then the Company measures the amount of the impairment by comparing the carrying amount of the asset with its estimated fair value. Such analyses necessarily involve significant judgments and estimations on the part of the Company. For the years ended December 31, 2018 , 2017 and 2016 , the Company determined that no impairment charge was necessary. Lease Accounting The Company accounts for operating lease transactions by recording rent expense on a straight-line basis over the expected life of the lease, commencing on the date it gains possession of leased property. The Company includes tenant improvement allowances and rent holidays received from landlords and the effect of any rent escalation clauses as adjustments to straight-line rent expense over the expected life of the lease. Capital lease transactions are reflected as a liability at the inception of the lease based on the present value of the minimum lease payments or, if lower, the fair value of the property. Assets under capital leases are recorded in Property and Equipment, net on the consolidated balance sheets and depreciated in a manner similar to other Property and Equipment. Fair Value Measurements The fair values of the Company’s financial instruments reflect the amounts that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The carrying amounts of the Company’s financial instruments of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and deferred revenue approximate fair value due to their short maturities. In addition, the Company carries its contingent consideration liabilities related to acquisitions at fair value. In accordance with the three-tier fair value hierarchy, the Company determined the fair value of its contingent consideration liabilities using the income approach with assumed discount rates and payment probabilities. The income approach uses Level 3, or unobservable inputs as defined under the accounting guidance for fair value measurements. On December 31, 2017 , the Company’s contingent consideration liability had a fair value of $5.0 million . The Company paid the full amount of the contingent consideration in April 2018. See Note 2— Acquisitions for more information regarding the Company’s contingent consideration liabilities. As part of the Lovoo Acquisition, the Company amended and restated its term loan and revolving credit facility. The Company carries a term loan facility with an outstanding balance of $36.9 million and $56.3 million at December 31, 2018 and 2017 , respectively. The outstanding balance as of December 31, 2018 approximates fair value due to the variable market interest rates and relatively short maturity associated with the Term Loan Facility. See Note 7— Long-Term Debt for more information regarding the Company’s credit facilities. The Company leases certain fixed assets under capital leases that expire in 2021. The capital leases are for the Company's data centers, printers and other furniture in the Company's German offices. The outstanding balance approximates fair value due to the relatively short maturities associated with these capital leases for the years ended December 31, 2018 and 2017 . The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the Financial Accounting Standards Board’s (“FASB”) fair value measurement guidance (ASU 2011-04), the Company is measuring the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. In 2017, the Company entered into an interest rate swap, interest rate cap and a cross-currency interest rate swap. See Note 13— Derivatives and Hedging Activities for further details. Foreign Currency The functional currency of our foreign subsidiaries is the local currency. The financial statements of these subsidiaries are translated to U.S. dollars using period-end rates of exchange for assets and liabilities and average quarterly rates of exchange for revenues and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Net gains and losses resulting from foreign exchange transactions are included in other income (expense). Net Income (Loss) per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants using the average market prices during the period. The following table shows the computation of basic and diluted net income (loss) per share for the following: For the Year Ended December 31, 2018 2017 2016 Numerator: Net income (loss) $ 1,143,388 $ (64,591,727 ) $ 46,268,618 Denominator: Weighted-average shares outstanding— basic 73,085,542 68,743,956 51,963,702 Effect of dilutive securities 2,530,897 — 5,781,950 Weighted-average shares outstanding— diluted 75,616,439 68,743,956 57,745,652 Basic income (loss) per share $ 0.02 $ (0.94 ) $ 0.89 Diluted income (loss) per share $ 0.02 $ (0.94 ) $ 0.80 The following table summarizes the number of dilutive securities, which may dilute future earnings per share, outstanding for each of the periods presented, but not included in the calculation of diluted loss per share: For the Year Ended December 31, 2018 2017 2016 Stock options 3,236,900 5,653,141 2,832,961 Unvested restricted stock awards 2,147,885 3,534,558 — Unvested PSUs 363,660 — — Warrants — — 345,202 Totals 5,748,445 9,187,699 3,178,163 Significant Customers and Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, and accounts receivable. The Company invests its excess cash in high-quality, liquid money market funds maintained by major U.S. banks and financial institutions. The Company has not experienced any losses on its cash equivalents. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Except with respect to a significant write-off in 2015, the Company has no history of significant losses from uncollectible accounts. During the year ended December 31, 2018 , two customers, and during each of the years ended December 31, 2017 and 2016 , three customers, all of which were advertising aggregators, which represent thousands of advertisers, comprised approximately 47% , 46% and 50% of total revenues, respectively. Three and five customers, all of which were advertising aggregators, which represent thousands of advertisers, comprised approximately 36% and 61% of accounts receivable as of December 31, 2018 and 2017 , respectively. The Company does not expect its current or future credit risk exposure to have a significant impact on its operations. However, there can be no assurance that the Company’s business will not experience any adverse impact from credit risk in the future. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In the event that the Company determines that it will not be able to realize its deferred income tax assets in the future in excess of its net recorded amount, the Company will make an adjustment to the valuation allowance, which will increase the provision for income taxes. The Tax Cuts and Jobs Act (“Tax Act”) was enacted on December 22, 2017, most provisions of which became effective in 2018. The Tax Act made substantial changes to U.S. taxation of corporations, including lowering the U.S. federal corporate income tax rate from 35% to 21% and instituting a territorial tax system, along with a on

Acquisitions	Acquisitions Lovoo On September 18, 2017, the Company, TMG Holding Germany GmbH, a limited liability company organized under the laws of Germany and a wholly-owned subsidiary of the Company, entered into a Share Purchase Agreement (the “Purchase Agreement”) with Bawogo Ventures GmbH & Co. KG, a limited partnership organized under the laws of Germany and the seller guarantors, to purchase all of the outstanding shares of Lovoo, a limited liability company incorporated under the laws of Germany (the “Lovoo Acquisition”), for total consideration of $86.1 million , including working capital. The Lovoo Acquisition closed on October 19, 2017 . The Company does not expect goodwill to be deductible for tax purposes. Included in the total consideration of $86.1 million is a $5.0 million contingent consideration in the form of an earn-out which is subject to certain conditions set forth in the Purchase Agreement, including the successful achievement of an Adjusted EBITDA target by Lovoo for the year ended December 31, 2017. Based on the probability of achieving the financial targets, the Company determined that the fair value of the contingent consideration at the closing date and December 31, 2017 was $5.0 million . The Company paid the full amount of the contingent consideration in April 2018. At the closing of the Lovoo Acquisition, the Company granted restricted stock awards representing an aggregate of 531,500 shares of common stock to 96 former Lovoo employees as an inducement material to becoming non-executive employees of the Company. The Company funded the Lovoo Acquisition from cash on hand and from a $60.0 million term credit facility from several banks and other financial institutions party thereto and JP Morgan Chase Bank, N.A., as administrative agent.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting Standards Codification Topic 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes among the following: Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly. Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Derivative financial instruments Currently, the Company uses an interest rate swap, interest rate cap and a cross currency swap to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of the interest rate swap and the cross currency swap are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The fair value of the interest rate cap is determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the cap. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the Company’s derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. In accordance with the FASB’s fair value measurement guidance in ASU 2011-04, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company has determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of the Company’s derivatives held as of December 31, 2018 and 2017 were classified as Level 2 of the fair value hierarchy. See Note 13— Derivatives and Hedging Activities for further discussion on derivative financial instruments. Recurring Fair Value Measurements Items measured at fair value on a recurring basis include money market mutual funds, restricted cash, derivatives and hedging instruments and contingent consideration. During the periods presented, the Company has not changed the manner in which it values assets and liabilities that are measured at fair value using Level 3 inputs. The following fair value hierarchy table presents information about each major category of the Company’s financial assets and liabilities measured at fair value on a recurring basis: Quoted Prices in Active Markets for Identical Items (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total December 31, 2018 Assets Money market $ 7,639,866 $ — $ — $ 7,639,866 Derivative asset — 972,784 — 972,784 Total assets $ 7,639,866 $ 972,784 $ — $ 8,612,650 Liabilities Derivative liability $ — $ 940,216 $ — $ 940,216 Total liabilities $ — $ 940,216 $ — $ 940,216 December 31, 2017 Assets Money market $ 1,390,714 $ — $ — $ 1,390,714 Restricted cash 894,551 — — 894,551 Derivative asset — 739,606 — 739,606 Total assets $ 2,285,265 $ 739,606 $ — $ 3,024,871 Liabilities Contingent consideration $ — $ — $ 5,000,000 $ 5,000,000 Derivative liability — 3,067,572 — 3,067,572 Total liabilities $ — $ 3,067,572 $ 5,000,000 $ 8,067,572 For non-recurring fair value measurements, see Note 4— Goodwill . The following table sets forth a summary of changes in the fair value of the Company’s Common Stock warrant liability and contingent consideration, which represent recurring measurements that are classified within Level 3 of the fair value hierarchy, wherein fair value is estimated using significant unobservable inputs: Contingent Consideration Balance as of December 31, 2016 $ 3,000,000 Amounts acquired 5,000,000 Changes in estimated fair value (102,734 ) Payments (2,897,266 ) Balance as of December 31, 2017 5,000,000 Payments (5,000,000 ) Balance as of December 31, 2018 $ — The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers within the hierarchy during the years ended December 31, 2018 and 2017 . The Company determined the fair value of its contingent consideration liabilities using the income approach with assumed discount rates and payment probabilities. The income approach uses Level 3, or unobservable inputs, as defined under the accounting guidance, for fair value measurements. Based on the Company’s projected results, the Company estimated the probability of success to be 100% for the contingent consideration related to the Lovoo Acquisition as of December 31, 2017. The Company paid the full amount of the contingent consideration in April 2018.

Goodwill [Abstract]
Goodwill	Goodwill The Company assesses goodwill for impairment annually, or more frequently whenever events or changes in circumstances indicate that an impairment may exist. Goodwill is tested for impairment at the reporting unit level. The Company believes it has two reporting units, The Meet Group US and Lovoo. As of October 1, 2018 , the Company completed its annual impairment test. In prior years, the Company performed its annual goodwill impairment test as of December 31st of a given calendar year. This change was made to more align with the Company’s internal forecasting process. The Company considered both a market approach using comparable company method and income approach using a discounted cash flow method which it believes to be an appropriate valuation methodology. The major assumptions in the market approach include the selected multiples applied to certain operating statistics, such as sales revenues as well as an estimated control premium. The Company’s discounted cash flow model is highly reliant on various assumptions, including estimates of future cash flows, growth rates, discount rate, expectations about variations in the amount and timing of cash flows and the probability of achieving its estimated cash flow forecast. These assumptions are based on significant inputs not easily observable in the market and thus represent Level 3 measurements within the fair value hierarchy. For The Meet Group US valuation, a discount rate of 13.5% was used, as well as assumptions of a slight decrease in revenue for the full year of 2018 of 0.6% , as compared to full year 2017, and subsequent increases in revenue growth of 12.7% , 20.0% , 12.8% , 6.7% and 6.6% in 2019 , 2020 , 2021 , 2022 and 2023 , respectively, before a terminal value was estimated. For the Lovoo valuation, a discount rate of 15.0% was used, as well as assumptions of increases in revenue for the full year of 2018 of 38.9% , as compared to full year 2017, and subsequent increases in revenue growth of 25.5% , 20.2% , 10.6% , 10.0% and 5.5% in 2019 , 2020 , 2021 , 2022 and 2023 , respectively, before a terminal value was estimated. The discount rates were determined using the weighted average cost of capital for a typical market participant. The Company also notes that the conclusion of value was not overly sensitive to changes in the growth rates used in our analysis. Had the growth rates for the next 5 years been 1% lower, the aggregate valuation conclusion would have decreased by less than 2.5% . The Company believes the discount rate and other inputs and assumptions are reasonable and consistent with those that a market participant would use. At October 1, 2018 , the Company concluded that the fair value of the Company’s reporting units exceeded their carrying value. The fair value for The Meet Group US and Lovoo were $296.6 million and $107.0 million , respectively, which was more than 97.1% and 81.8% greater than the reporting units’ carrying value, respectively. In the fourth quarter of 2017, through the Company’s annual testing of goodwill, the Company determined that a $56.4 million one-time, non-cash impairment was required for our U.S. reporting unit, due predominantly to the market-driven impacts on advertising revenue resulting from lower cost per thousand (“CPM”) impressions which negatively affected the Company’s results and outlook. This non-cash impairment charge does not impact the Company’s ability to generate cash flow in the future and it is not tax deductible. As a result of this impairment charge, the fair value of goodwill for the US operations was $95.2 million as of December 31, 2017. The Company classifies goodwill as a non-recurring Level 3 measurement. The following table sets forth a summary of changes goodwill: Goodwill Balance at December 31, 2016 $ 114,175,554 Goodwill acquired from if(we) Acquisition 37,489,373 Goodwill acquired from Lovoo Acquisition 54,677,878 Goodwill impairment (56,428,861 ) Foreign currency translation adjustments 780,191 Balance at December 31, 2017 150,694,135 Foreign currency translation adjustments (2,561,262 ) Balance at December 31, 2018 $ 148,132,873

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Capital Leases The Company leases certain fixed assets under capital leases that expire through 2021. The capital leases are for the Company’s data centers, printers and other furniture in the Company’s German offices. Principal and interest are payable monthly at interest rates ranging from 3.9% to 7.8% per annum, rates varying based on the type of leased asset. The Company did not enter into any new capital lease agreements for the year ended December 31, 2018 . Operating Leases and Cloud Data Storage The Company leases its operating facilities in the U.S. under certain noncancelable operating leases that expire in 2022. The Company also leases operating facilities in Germany under certain noncancelable operating leases that expire in 2020. These leases are renewable at the Company’s option. Lovoo also stores a majority of its user and business data in the Google Cloud Platform under a noncancelable minimum commitment agreement that expires in 2023. A summary of minimum future rental payments required under capital and operating leases as of December 31, 2018 are as follows: Capital Operating Cloud Data Storage 2019 $ 139,001 $ 1,789,672 $ 456,406 2020 54,536 950,156 650,817 2021 4,806 612,619 967,663 2022 — 283,302 1,064,429 2023 — — 1,170,872 2024 — — — Total minimum payments 198,343 $ 3,635,749 $ 4,310,187 Less: Amount representing interest 5,593 Total present value of minimum payments 192,750 Less: Current portion of such obligations 134,067 Long-term capital lease obligations $ 58,683 Rent expense for the operating leases was $3.9 million , $4.7 million and $2.0 million in 2018 , 2017 and 2016 , respectively. New Term Loan Facility A summary of minimum future principal payments under our New Term Loan Facility as of December 31, 2018 are as follows: New Term Loan Facility (1) 2019 $ 18,566,584 2020 18,373,574 Total minimum loan payments $ 36,940,158 (1) Interest rates on the New Term Loan Facility are variable in nature, however, the Company is party to a fixed-pay amortizing interest rate swap having a remaining notional amount of $26.3 million and a non-amortizing interest rate cap with a notional amount of $10.7 million . If interest rates were to remain at the December 31, 2018 level, the Company would receive interest payments of $0.1 million and $0.01 million in 2019 and 2020 , respectively, of net settlements on the fixed-pay amortizing interest rate swap. Litigation From time to time, we are party to certain legal proceedings that arise in the ordinary course and are incidental to our business. We operate our business online, which is subject to extensive regulation by federal and state governments. On September 29, 2015, the Company filed suit in the Court of Common Pleas of Philadelphia County, Pennsylvania, against Beanstock Media, Inc. (“Beanstock”) and Adaptive Medias, Inc. (“Adaptive”) for collection of approximately $10 million , in the aggregate, due under the Media Publisher Agreement (the “Web Agreement”) entered into on September 25, 2013 and the Advertising Agreement (the “Mobile Agreement”) entered into on December 23, 2014. Pursuant to the Web Agreement, Beanstock had the exclusive right and obligation to fill all of the Company’s remnant desktop in-page display advertising inventory on www.meetme.com (the “Site”), excluding, (i) any inventory sold to a third party under an insertion order that was campaign or advertiser specific, (ii) any inventory the Company reserved in existing and future agreements with third parties for barter transactions and as additional consideration as part of larger business development transactions, and (iii) any inventory reserved for premium advertising for the Site. Pursuant to the Mobile Agreement, Beanstock had the right and obligation to fill substantially all of the Company’s advertising inventory on its MeetMe mobile app for iOS and Android, as well as the Site when accessed using a mobile device and as optimized for mobile devices (collectively, the “App”). The Mobile Agreement did not apply to interstitially placed advertisements, advertisements on versions of the App specific to the iPad and other Apple tablet devices, other mobile apps or in-app products or features on the App, including, without limitation, offer wall features and the Company’s Social Theater business. On September 28, 2015, Adaptive filed suit in the Superior Court of California, County of Orange, against the Company, Beanstock, et al., alleging, in pertinent part, that the Company “aided and abetted” an individual who was an officer and director of Adaptive to breach his fiduciary duty to Adaptive with respect to Adaptive’s joining the Mobile Agreement. Adaptive’s complaint sought from the Company $600,000 plus unspecified punitive damages. On January 20, 2016, the Company received notice from the United States Bankruptcy Court, District of Delaware, that a Chapter 7 bankruptcy case against Beanstock had been filed on October 7, 2015. Both of the state court actions were stayed by the courts as a result of the bankruptcy filing against Beanstock. Adaptive’s suit against the Company remained stayed until Adaptive indicated that it no longer wanted to pursue the matter and, on or about November 20, 2017, filed a voluntary request for dismissal without prejudice of the action and all claims against the parties, including the Company, which dismissal was entered by the Court on the same day. The Company was not required to take any action or pay any sum in connection with the dismissal. Adaptive’s suit against the Company is, therefore, resolved. Future events or circumstances, currently unknown to management, will determine whether the resolution of pending or threatened litigation or claims will ultimately have a material effect on our consolidated financial position, liquidity or results of operations in any future reporting periods. Retirement Plan The Company maintains The Meet Group, Inc. 401(k) Retirement Plan (the “Plan”), which is a savings and investment plan intended to be qualified under of the Internal Revenue Code. The Plan covers the majority of the employees of the Company. In January 2014, the Company began providing company matching contributions to the plan, based on a participant’s contribution. The Company’s 401(k) match expense totaled $0.8 million , $0.7 million and $0.4 million in 2018 , 2017 and 2016 , respectively. The expense is included in sales and marketing, product development and content, and general and administrative expenses in the consolidated statements of operations and comprehensive income (loss).

Equity [Abstract]
Stockholder's Equity	Stockholder’s Equity Preferred Stock The total number of shares of preferred stock, $.001 par value, that the Company is authorized to issue is 5,000,000 . The Board of Directors may, without further action by the stockholders, issue a series of Preferred Stock and fix the rights and preferences of those shares, including the dividend rights, dividend rates, conversion rights, exchange rights, voting rights, terms of redemption, redemption price or prices, liquidation preferences, the number of shares constituting any series and the designation of such series. On March 1, 2017, the Company filed with the Secretary of State of the State of Delaware a Certificate of Elimination of the 1,000,000 shares of Series A-1 Preferred Stock that effectuated the elimination of the Series A-1 Preferred Stock, which then resumed the status of authorized but unissued shares of preferred stock. As of December 31, 2017, there were no longer any Series A-1 shares authorized or issued and outstanding. Common Stock The total number of shares of common stock, $0.001 par value, that the Company is authorized to issue is 100,000,000 . In March 2017, the Company completed the underwritten public offering and sale of 9,200,000 shares (the “Shares”) of common stock at a price to the public of $5.00 per share. The net proceeds from the sale of the Shares, after deducting the underwriters’ discount and other offering expenses, were approximately $43.0 million . The Offering was conducted pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-190535), filed with the SEC under the Securities Act of 1933, as amended (the “Securities Act”) and declared effective on April 18, 2014. The Company issued shares of common stock of 1,079,496 and 2,080,648 related to exercises of stock options and 1,591,662 and 1,013,763 related to restricted stock awards in 2018 and 2017 , respectively. The Company issued 111,350 shares of common stock to a terminated employee related to performance share awards in 2018 . The Company did not issue any shares of common stock related to performance share awards in 2017. No shares of common stock related to the exercise of warrants were issued in 2018 , while 675,000 were issued in 2017 . No warrants expired in 2018 and 2017 . In September 2015, the Board of Directors authorized a $1 million share repurchase program (the “2015 Repurchase Program”) relating to the Company’s common stock. In October 2015, the Board of Directors increased the authorized amount to $3 million . The 2015 Repurchase Program expired on April 30, 2016. The Company did not repurchase any of our common stock under the 2015 Repurchase Program. On August 29, 2016, the Board of Directors authorized a $15 million share repurchase program (the “2016 Repurchase Program”). Repurchases under the 2016 Repurchase Program were made in the open market or through privately negotiated transactions intended to comply with SEC Rule 10b-18, subject to market conditions, applicable legal requirements, and other relevant factors. During the year ended December 31, 2016, the Company repurchased 848,145 shares for an aggregate purchase price of $5.0 million . These shares were immediately retired. The 2016 Repurchase Program was terminated on August 29, 2017; consequently, the Company did not repurchase any shares during the year ended December 31, 2018 and 2017. Stock-Based Compensation The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model, based on weighted average assumptions. Expected volatility is based on historical volatility of the Company’s common stock. The risk-free rate is based on the U.S. Treasury yield curve in effect over the expected term at the time of grant. Compensation expense is recognized on a straight-line basis over the requisite service period of the award. During 2018 , 2017 and 2016 , the Company continued to use the simplified method to determine the expected option term since the Company’s stock option exercise experience does not provide a reasonable basis upon which to estimate the expected option term. The Company began granting restricted stock awards (“RSAs”) to its employees in April 2013. The fair value of RSAs is determined using the fair value of the Company’s common stock on the date of grant. Stock-based compensation expense for RSAs is amortized on a straight-line basis over the requisite service period. RSAs generally vest over a three -year period with 33% vesting at the end of one year and the remaining vesting annually thereafter. The Company began granting performance stock awards (“PSUs”) to certain employees in April 2018. The fair value of PSUs is estimated using a Monte-Carlo simulation model utilizing several key assumptions including expected Company and Russell 2000 Peer Group share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The assumptions used in calculating the fair value of stock-based awards represent the Company’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period of all awards given by the Company.

Equity [Abstract]
Warrant Transactions	Stockholder’s Equity Preferred Stock The total number of shares of preferred stock, $.001 par value, that the Company is authorized to issue is 5,000,000 . The Board of Directors may, without further action by the stockholders, issue a series of Preferred Stock and fix the rights and preferences of those shares, including the dividend rights, dividend rates, conversion rights, exchange rights, voting rights, terms of redemption, redemption price or prices, liquidation preferences, the number of shares constituting any series and the designation of such series. On March 1, 2017, the Company filed with the Secretary of State of the State of Delaware a Certificate of Elimination of the 1,000,000 shares of Series A-1 Preferred Stock that effectuated the elimination of the Series A-1 Preferred Stock, which then resumed the status of authorized but unissued shares of preferred stock. As of December 31, 2017, there were no longer any Series A-1 shares authorized or issued and outstanding. Common Stock The total number of shares of common stock, $0.001 par value, that the Company is authorized to issue is 100,000,000 . In March 2017, the Company completed the underwritten public offering and sale of 9,200,000 shares (the “Shares”) of common stock at a price to the public of $5.00 per share. The net proceeds from the sale of the Shares, after deducting the underwriters’ discount and other offering expenses, were approximately $43.0 million . The Offering was conducted pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-190535), filed with the SEC under the Securities Act of 1933, as amended (the “Securities Act”) and declared effective on April 18, 2014. The Company issued shares of common stock of 1,079,496 and 2,080,648 related to exercises of stock options and 1,591,662 and 1,013,763 related to restricted stock awards in 2018 and 2017 , respectively. The Company issued 111,350 shares of common stock to a terminated employee related to performance share awards in 2018 . The Company did not issue any shares of common stock related to performance share awards in 2017. No shares of common stock related to the exercise of warrants were issued in 2018 , while 675,000 were issued in 2017 . No warrants expired in 2018 and 2017 . In September 2015, the Board of Directors authorized a $1 million share repurchase program (the “2015 Repurchase Program”) relating to the Company’s common stock. In October 2015, the Board of Directors increased the authorized amount to $3 million . The 2015 Repurchase Program expired on April 30, 2016. The Company did not repurchase any of our common stock under the 2015 Repurchase Program. On August 29, 2016, the Board of Directors authorized a $15 million share repurchase program (the “2016 Repurchase Program”). Repurchases under the 2016 Repurchase Program were made in the open market or through privately negotiated transactions intended to comply with SEC Rule 10b-18, subject to market conditions, applicable legal requirements, and other relevant factors. During the year ended December 31, 2016, the Company repurchased 848,145 shares for an aggregate purchase price of $5.0 million . These shares were immediately retired. The 2016 Repurchase Program was terminated on August 29, 2017; consequently, the Company did not repurchase any shares during the year ended December 31, 2018 and 2017. Stock-Based Compensation The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model, based on weighted average assumptions. Expected volatility is based on historical volatility of the Company’s common stock. The risk-free rate is based on the U.S. Treasury yield curve in effect over the expected term at the time of grant. Compensation expense is recognized on a straight-line basis over the requisite service period of the award. During 2018 , 2017 and 2016 , the Company continued to use the simplified method to determine the expected option term since the Company’s stock option exercise experience does not provide a reasonable basis upon which to estimate the expected option term. The Company began granting restricted stock awards (“RSAs”) to its employees in April 2013. The fair value of RSAs is determined using the fair value of the Company’s common stock on the date of grant. Stock-based compensation expense for RSAs is amortized on a straight-line basis over the requisite service period. RSAs generally vest over a three -year period with 33% vesting at the end of one year and the remaining vesting annually thereafter. The Company began granting performance stock awards (“PSUs”) to certain employees in April 2018. The fair value of PSUs is estimated using a Monte-Carlo simulation model utilizing several key assumptions including expected Company and Russell 2000 Peer Group share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The assumptions used in calculating the fair value of stock-based awards represent the Company’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period of all awards given by the Company. Stock-based compensation expense includes incremental stock-based compensation expense and is allocated on the consolidated statements of operations and comprehensive income (loss) as follows: For the Years Ended December 31, 2018 2017 2016 Sales and marketing $ 903,713 $ 439,797 $ 354,088 Product development and content 4,767,804 4,008,545 1,528,547 General and administrative 3,614,333 4,018,936 1,685,352 Total stock-based compensation expense $ 9,285,850 $ 8,467,278 $ 3,567,987 As of December 31, 2018 , there was approximately $1.8 million , $9.4 million and $1.5 million of total unrecognized compensation cost which is expected to be recognized over a weighted-average vesting period of approximately of 1.2 years , 1.9 years and 2.3 years relating to stock options, RSAs and PSUs, respectively.

Performance Share Awards Under 2018 Omnibus Incentive Plan In 2018 , the Company granted 60,000 PSUs under the 2018 Plan based on a relative TSR metric over a performance period spanning three years from the grant date of the PSU. Expense related to these awards will be expensed on a straight-line basis over the three -year term of the award with a credit to additional paid-in-capital. PSUs will vest at the end of the performance period and will be paid immediately in shares of common stock. PSUs are forfeited if the participant is no longer employed on the third anniversary of the grant date, except in the event of an involuntary termination, death, disability or change in control. PSU share payouts range from a threshold of 33% to a maximum of 170% based on the relative ranking of the Company’s TSR as compared to the TSR of the companies in the Russell 2000 Peer Group. The PSU award stipulates certain limitations to the payout in the event the payout reaches a defined ceiling level or the Company’s TSR is negative. The estimated fair value of the PSU awards at the date of grant was $0.3 million .

The estimated fair value of the PSU awards at the date of grant was $1.8 million . The Company estimated the fair value of the PSU awards using a Monte-Carlo simulation model utilizing several key assumptions including expected Company and Russell 2000 Peer Group share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. A summary of PSU awards under the 2012 Plan in 2018 is as follows: PSUs Number of Weighted-Average Outstanding at December 31, 2017 — $ — Granted 615,500 2.94 Vested (65,500 ) 2.94 Forfeited or expired — — Outstanding at December 31, 2018 550,000 2.94 The Company issued 111,350 in connection the vesting of PSUs as part of a severance agreement with an officer of the Company in 2018 .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company provides for income taxes under the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company recorded a U.S. net benefit for income taxes of $0.8 million , expense of $6.6 million and benefit of $27.9 million in 2018 , 2017 and 2016 , respectively. As a results of the purchase of Lovoo, GmbH in October 2017, the Company recorded a provision for German income taxes of approximately $1.3 million and $0.2 million in 2018 and 2017 , respectively. The provision for income taxes for 2018 , 2017 and 2016 , consists of the following: 2018 2017 2016 Federal: Current $ (81,803 ) $ 20,870 $ 150,233 Deferred 472,908 6,637,417 (26,783,983 ) Total federal 391,105 6,658,287 (26,633,750 ) State: Current 47,499 (32,456 ) 71,120 Deferred (1,222,786 ) (74,368 ) (1,312,732 ) Total state (1,175,287 ) (106,824 ) (1,241,612 ) Foreign: Current 1,211,602 293,331 — Deferred 40,036 (141,194 ) — Total foreign 1,251,638 152,137 — Provision (benefit) for income taxes $ 467,456 $ 6,703,600 $ (27,875,362 ) Deferred taxes are recognized for temporary differences between the basis of assets and liabilities for financial statement and income tax purposes. The significant components of the Company’s deferred tax assets are comprised of the following: December 31, 2018 December 31, 2017 Deferred tax assets: Net operating loss carryforward $ 16,835,393 $ 18,092,988 Property and equipment — 326,229 Stock options and warrants 3,125,070 2,796,366 Federal and state tax credits 5,472,586 6,208,362 Accrued liabilities and other reserves 1,188,607 1,514,995 Other comprehensive income 206,417 309,436 Other — 476,910 Total deferred tax assets 26,828,073 29,725,286 Valuation allowance (2,299,805 ) (2,512,045 ) Net deferred tax assets 24,528,268 27,213,241 Deferred tax liabilities Property and equipment (67,991 ) — Amortization of intangible assets (8,707,035 ) (11,692,027 ) Other (104,670 ) — Total deferred tax liabilities (8,879,696 ) (11,692,027 ) Net deferred tax assets $ 15,648,572 $ 15,521,214 As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets (primarily federal and state net operating losses (NOLs)). As of December 31, 2018 , the Company has achieved three years of cumulative adjusted pretax income in the U.S. federal and state tax jurisdiction. The Company has determined that there is sufficient positive evidence to conclude that it is more likely than not that net deferred tax assets, before valuation allowance, of $26.8 million are realizable, except for certain Florida NOLs, Pennsylvania NOLs that, starting in 2017, are limited to 30% of taxable income, increasing to 35% of taxable income in 2018 and 40% of taxable income in years after 2018. Upon acquisition, the Company determined that a valuation allowance was required for certain if(we) California net operating losses and credits that were not more likely than not to be realized. The Company believes it is more likely than not that the foreign deferred tax assets are realizable due to reversing deferred tax liabilities. A reconciliation of income tax expense computed at the statutory federal income tax rate of 21% to income taxes as reflected in the financial statements is as follows: 2018 2017 2016 U.S. federal income tax at statutory rate $ 340,074 $ (20,260,844 ) $ 6,437,639 State tax benefit, net of federal provision (benefit) (53,732 ) (21,096 ) (1,266,504 ) Effect of rates different than statutory 465,945 (311,304 ) — Goodwill impairment — 19,750,101 — Windfall tax benefit 263,499 (2,155,157 ) (2,957,837 ) Fair market value adjustment for warrants — — 302,609 Transaction costs — 819,251 607,528 Sec. 162(m) Excess Officer's Compensation 100,247 283,351 476,339 Nondeductible expenses 61,962 825,169 56,018 Stock compensation forfeitures and other — 562,155 1,195,454 Loss on foreign investments — — (649,998 ) Rate change 102,717 7,670,606 (909,045 ) Dissolution of foreign entity — (1,124,781 ) — Repatriation tax (81,802 ) 81,808 — Change in valuation allowance (212,239 ) 731,250 (31,247,234 ) Foreign subsidiary loss with no tax benefit — — 7,485 GILTI 251,370 — — Additional State NOLs (765,222 ) — — Other (5,363 ) (146,909 ) 72,184 Provision (benefit) for income taxes $ 467,456 $ 6,703,600 $ (27,875,362 ) The Tax Cuts and Jobs Act (“Tax Act”) was enacted on December 22, 2017, most provisions of which became effective in 2018. The Tax Act made substantial changes to U.S. taxation of corporations, including lowering the U.S. federal corporate income tax rate from 35% to 21% and instituting a territorial tax system, along with a one-time tax on accumulated foreign earnings. Upon enactment, the Company remeasured its deferred tax balances to reflect the new 21% U.S. federal tax rate, which resulted in a tax expense of $7.7 million in 2017. The Company also recorded a provisional liability for the one-time U.S. tax of $0.1 million , triggered by the Tax Act, on accumulated foreign earnings. This provisional liability was fully reversed during the current year. Another provision of the Tax Act subjects performance–based compensation paid to certain covered employees to the limitation on the deductibility of executive compensation under Section 162(m) of the Internal Revenue Code. As a result of this provision the future payment of stock based compensation for which deferred tax assets exist as December 31, 2018 may be nondeductible in the future year in which it is paid. The Company’s accounting policy is to treat stock based compensation as deductible first and to apply the limitation to cash based compensation in the year of payment. Based on information available at this time it is assumed that these future payments will be deductible and that any limitation on the deductibility will be applied to other compensation paid in the year of payment. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, the Company has closed its accounting for the impacts of the Tax Act. Accordingly, the Company determined that there was no liability in connection with the transition tax on the mandatory deemed repatriation of foreign earnings. The Company calculated the impact of the Global Intangible Low-Taxed Income (“GILTI”) provision of the Tax Act to be an expense of approximately $0.3 million in the current year. The GILTI provision imposes taxes on foreign earnings in excess of a deemed return on tangible assets. The Company has elected to treat the GILTI tax as a period cost; as such, no deferred taxes have been recorded with respect to GILTI. The Company recorded an additional benefit for state operating losses in the current year as a result of additional apportionment in an existing state and legislative changes during the year in Pennsylvania which increased the limitation on the amount of carryforward that can be used each year. The deferred tax assets at both December 31, 2018 and 2017 are principally the result of net operating loss carryforwards of $63.1 million and $68.6 million for Federal and $49.1 million and $50.1 million , for state purposes, respectively, which substantially begin to expire in 2027 and through 2037. The net operating loss carryforward at December 31, 2018 includes $16.9 million of Skout NOLs on which the Company performed an Internal Revenue Code Section 382 study which concluded that $1.3 million of a total of $18.2 million would be unusable due to annual limitation. Previously, the Company had completed an Internal Revenue Code Section 382 study to determine annual limitations on the usability of the Company’s net operating loss carryforwards due to historical changes in ownership. The amount of federal NOL carryforwards as of December 31, 2018 disclosed above do not include $63.3 million of The Meet Group, Inc. NOL carryforwards that are expected to expire unutilized pursuant to the Section 382 study. In accordance with ASC 740-10, Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109 , the Company has analyzed its tax position in all jurisdictions where it is required to file an income tax return and the Company has not recognized a benefit for uncertain tax positions. With respect to purchase accounting associated with the if(we) acquisition, a liability for uncertain tax positions was established in the amount of $2.0 million . If the unrecognized tax benefit is recognized it will impact the effective tax rate of the Company. All of the uncertain tax position has been recorded as a reduction to the related deferred tax asset for the credit carryforward in accordance with Accounting Standards Update 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists for all periods. The total amount of unrecognized tax benefits is not expected to increase or decrease within 12 months of the reporting date. The following is a tabular reconciliation of total amounts of unrecognized tax benefits: 2018 Unrecognized tax liabilities— January 1 $ 2,029,653 Gross increases — Unrecognized tax liabilities— December 31 $ 2,029,653 The Company will recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2018 and 2017 , the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s statements of operations and comprehensive income (loss) for the years ended December 31, 2018 , 2017 and 2016 . The Company files income tax returns in the U.S. and various state and foreign jurisdictions. The federal and state income tax returns are generally subject to tax examinations for the tax years ended December 31, 2014 through December 31, 2018 . To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal Revenue Service, state or foreign tax authorities to the extent utilized in a future period. The Company does not expect to repatriate any earnings in foreign subsidiaries, and therefore no accrual for withholding or other taxes has been made. The Company will continue to monitor any excess financial reporting over tax basis in our investments in foreign subsidiaries that may arise in future periods, and withholding taxes or other taxes would be recorded for any amounts not considered permanently reinvested, if applicable.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings. Certain of the Company’s foreign operations expose the Company to fluctuations of foreign exchange rates. These fluctuations may impact the value of the Company’s cash receipts and payments in terms of the Company’s functional currency. The Company enters into derivative financial instruments to protect the value or fix the amount of certain liabilities in terms of its functional currency, the U.S. dollar. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. During 2018 and 2017 , such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Gains and losses on the derivative representing hedge components excluded from the assessment of effectiveness are recognized over the life of the hedge on a systematic and rational basis, as documented at hedge inception in accordance with the Company’s accounting policy election. The earnings recognition of excluded components is presented in interest expense. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. During 2019 , the Company estimates that an additional $0.1 million will be reclassified as an decrease to interest expense. As of December 31, 2018 , the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk: Number of At Inception At December 31, 2018 Interest Rate Derivative Instruments Notional Notional Interest rate swaps 1 $45,000,000 $26,250,000 Interest rate caps 1 $15,000,000 $10,690,158 Cash Flow Hedges of Foreign Exchange Risk The Company is exposed to fluctuations in various foreign currencies against its functional currency, the US dollar. The Company uses foreign currency derivatives including cross-currency interest rate swaps to manage its exposure to fluctuations in the USD-EUR exchange rate. Cross-currency interest rate swaps involve exchanging fixed rate interest payments for fixed rate interest receipts both of which will occur at the USD-EUR forward exchange rates in effect upon entering into the instrument. The Company designates these derivatives as cash flow hedges of foreign exchange risks. For derivatives designated and that qualify as cash flow hedges of foreign exchange risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified in the period(s) during which the hedged transaction affects earnings within the same income statement line item as the earnings effect of the hedged transaction. During 2019 , the Company estimates that an additional $0.8 million will be reclassified as a decrease to interest expense. As of December 31, 2018 , the Company had the following outstanding foreign currency derivatives that were used to hedge its foreign exchange risks: Foreign Currency Derivative Number of Instruments Pay Fixed Notional Receive Fixed Notional Cross-currency interest rate swap 1 €42,000,517 $48,750,000 (amortizing to €37,692,772 as of December 31, 2018) (amortizing to $43,750,000 as of December 31, 2018) The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Balance Sheet as of December 31, 2018 and 2017 : Fair Value of Derivative Instruments Asset Derivatives Liability Derivatives As of December 31, As of December 31, 2018 2017 2018 2017 Derivatives Designated as Hedging Instruments Balance Sheet Location Fair Value Fair Value Fair Value Fair Value Interest rate products Other assets/liabilities - current $ 166,058 $ 243 $ — $ (71,915 ) Interest rate products Other assets - non-current 53,355 84,058 — — Cross currency contract Prepaid expenses and other current assets 753,371 655,305 — — Cross currency contract Long-term derivative liability — — (940,216 ) (2,995,657 ) Total derivatives designated as hedging instruments $ 972,784 $ 739,606 $ (940,216 ) $ (3,067,572 ) The table below presents the effect of cash flow hedge accounting on accumulated other comprehensive income (loss) as of December 31, 2018 , 2017 and 2016 : Derivatives in Subtopic 815-20 Hedging Relationships Amount of Gain (Loss) Recognized in OCI on Derivatives 2018 2017 2016 Derivatives in Cash Flow Hedging Relationships Interest rate products $ 289,415 $ (75,604 ) $ — Cross currency contract 2,797,400 (2,226,811 ) — Total $ 3,086,815 $ (2,302,415 ) $ — Location of Gain (Loss) Reclassified from Accumulated OCI into Income Amount of Gain (Loss) Reclassified from Accumulated OCI into Income 2018 2017 2016 Interest expense $ 54,846 $ (37,427 ) $ — Interest expense 866,365 147,223 — Gain (loss) on foreign currency transactions 2,063,057 (1,675,692 ) — Total $ 2,984,268 $ (1,565,896 ) $ — The table below presents the effect of the Company’s derivative financial instruments on the Income Statement as of December 31, 2018 , 2017 and 2016 .

Revenue from Contract with Customer [Abstract]
Revenue	Revenue On January 1, 2018, the Company adopted ASC Topic 606 “Revenue from Contracts with Customers,” (“ASC 606”) using the cumulative effect method (modified retrospective method) and applied to those contracts with customers which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are unadjusted and continue to be reported in accordance with the Company’s historic accounting under ASC Topic 605, “Revenue Recognition” (“ASC 605”). The Company recorded a net reduction to opening deferred revenue and a corresponding increase to retained earnings of $0.02 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The impact was related to MeetMe+ subscriptions, which were previously recognized using the revenue policy for credits under ASC 605. Under ASC 606, MeetMe+ subscription revenue will be recognized over the subscription period using a mid-month convention beginning on January 1, 2018. In accordance with the requirements of ASC 606, the disclosure of the impact of adoption on the Company’s consolidated income statement and balance sheet is as follows: Year Ended December 31, 2018 ASC 606 ASC 605 Effect of Change Income Statement Revenues $ 178,613,495 $ 178,614,441 $ (946 ) The following table presents the Company’s revenues disaggregated by revenue source for the years ended December 31, 2018 and 2017 : Year Ended December 31, 2018 2017 (1) 2016 (1) $ % $ % $ % User pay revenue $ 107,330,136 60.1 % $ 33,791,592 27.3 % $ 4,927,241 6.5 % Advertising 71,283,359 39.9 89,962,221 72.7 71,196,868 93.5 Total revenue $ 178,613,495 100.0 % $ 123,753,813 100.0 % $ 76,124,109 100.0 % (1) Prior period amounts have not been adjusted under the modified retrospective adoption method. Deferred Revenue The deferred revenue balance as of December 31, 2018 increased $107.3 million due to subscription and in-app purchases consideration received in advance of providing the good or service to the customers. This amount was offset by $107.0 million revenue recognized from deferred revenue due to performance obligations satisfied during 2018 . ASC 606 Practical Expedient Elections The Company elected the following practical expedients in applying ASC 606 to its revenue streams: Portfolio Approach - Contracts within each revenue stream have similar characteristics and the Company expects that the effects on the financial statements would not differ materially from applying this guidance to the individual contracts. As such, the Company applied the portfolio approach to its contracts. Sales Tax Exclusion from Transaction Price - The Company does not collect sales tax for advertising revenue. Sales taxes are added to the transaction price by the payment processors for subscription and in-app purchases, when applicable. However, these sales taxes are not included in the Company’s consideration amount. Contract Costs - The Company does not incur costs to obtain or fulfill contracts in most revenue streams. There are sales commissions incurred for Social Theater contracts, however these contracts are typically for a period of less than a year. As the costs are expected to be recognized in one year or less, these costs are recorded within sales and marketing expenses rather than being deferred and recognized over the term of the contract. Right to Invoice - Revenue from advertising contracts is recognized over time based on the Company’s performance completed to date. The Company will apply the invoice expedient and recognize revenue in the amount to which the entity has a right to invoice as measured by the amount of impressions or actions delivered within each period. Unsatisfied Performance Obligations - The Company’s disclosures exclude the value of unsatisfied performance obligations for (i) its contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for performance to date.

Subsequent Events [Abstract]
Subsequent Events	On March 5, 2019 , the Company acquired 100% of the issued and outstanding units of Initech, LLC, a privately held company that owns and operates Growlr, a leading same-sex social app, for total consideration of $11.8 million , plus an earnout of $2.0 million . Included in total consideration of $11.8 million is $4.8 million in cash on hand and a draw down of $7.0 million from the Company’s New Revolving Credit Facility. See Note 7— Long-Term Debt for further details on the New Revolving Credit Facility. The earnout of $2.0 million is to be paid in annual $1.0 million installments over the next two years if certain revenue metrics are achieved in each year. The Company has not provided an allocation of the preliminary purchase price as the initial accounting for the acquisition of Growlr is incomplete.

Description of Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). The consolidated financial statements include the accounts of all subsidiaries and affiliates in which the Company holds a controlling financial interest as of the date of the consolidated financial statements. The consolidated financial statements include the accounts of The Meet Group and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are required in the determination of business combinations, revenue recognition, accounting for business combinations, accounts receivable valuation, the fair value of financial instruments, the valuation of long-lived assets, valuation of deferred tax assets, income taxes, contingencies, goodwill and intangible assets, and stock-based compensation. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. The Company’s estimates often are based on complex judgments, probabilities and assumptions that it believes to be reasonable but that are inherently uncertain and unpredictable. For any given individual estimate or assumption made by the Company, there may also be other estimates or assumptions that are reasonable. The Company regularly evaluates its estimates and assumptions using historical experience and other factors, including the economic environment. As future events and their effects cannot be determined with precision, the Company’s estimates and assumptions may prove to be incomplete or inaccurate, or unanticipated events and circumstances may occur that might cause it to change those estimates and assumptions. Market conditions, such as illiquid credit markets, volatile equity markets, dramatic fluctuations in foreign currency rates and economic downturn, can increase the uncertainty already inherent in its estimates and assumptions. The Company adjusts its estimates and assumptions when facts and circumstances indicate the need for change. Those changes generally will be reflected in the Company’s consolidated financial statements on a prospective basis unless they are required to be treated retrospectively under the relevant accounting standard. It is possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. The Company is also subject to other risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in competition, litigation, legislation and regulations.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised good or service is transferred to the customer in an amount that the Company expects to be entitled in exchange for the good or service. User Pay Revenue User pay revenue is earned from in-app purchase products and subscriptions sold to mobile application and website users. The Company offers in-app products such as Credits, Points, Gold and Icebreakers (collectively, the “In-App Products”). Users purchase the In-App Products to exchange for the Company’s virtual products. The In-App Products allow users to engage with other users on the applications and in live video. They also put users in the spotlight, helping them get more attention from the community in order to meet more people faster. Platform users do not own the In-App Products but have a limited right to use the In-App Products on virtual products offered for sale on the Company’s platforms. In-App Products may be used to purchase virtual gifts for other users. These virtual gifts are received by other users and converted into Diamonds. Diamonds represent an intermediary currency that the Company manages. Diamonds can either be converted back into credits or may be used to claim rewards, including in some instances cash rewards. The In-App Products are not transferable, cannot be sold or exchanged outside of our platforms, are not redeemable for any sum of money, cannot be gifted to other users and can only be used on our platforms. The In-App Products are recorded in deferred revenue when purchased and recognized as revenue over time when: (i) the In-App Products are used by the customer; or (ii) the Company determines the likelihood of the In-App Products being redeemed by the customer is remote (breakage) and there is not a legal obligation to remit the unredeemed In-App Products to the relevant jurisdiction. The breakage rate is based upon Company-specific historical redemption patterns. Breakage is recognized in revenue as the In-App Products are used on a pro rata basis over a three or six -month period (life of the user) beginning at the date of the sale and are included in revenue in the condensed consolidated statements of operations and comprehensive income (loss). Breakage recognized in 2018 , 2017 and 2016 was $2.8 million , $1.5 million and $1.3 million , respectively. For MeetMe+, Tagged, Skout and Lovoo subscription-based products, the Company recognizes revenue over the term of the subscription. Under ASC 606, user pay revenue has a single performance obligation. Subscriptions provide customers with premium access to the application and include credits on MeetMe+, while In-App Product purchases are satisfied by standing ready to allow users to exchange the In-App Products for virtual products. The consideration received for these services is fixed at the time of purchase. The customer simultaneously receives and consumes the benefits of user pay features as the Company performs the services. Revenue is recorded in deferred revenue when purchased by customer and recognized as revenue over time as the performance obligation is satisfied. Advertising Revenue Advertising revenue is comprised of mobile and web advertising. Within each revenue stream, the Company has one performance obligation to publish advertisements as specified by the respective contracts. The amount of consideration that the Company expects to receive for the services is variable based on the volume of advertisement impressions. The Company does not offer any discounts or free impressions and has not historically experienced any collectability issues. The Company also recognizes revenue from cross-platform/social theater and cost-per-action (“CPA”) offers. Each of these revenue streams has one performance obligation. For cross-platform/social theater contracts, the consideration promised is fixed per ad campaign and term, and required services to be delivered. However, the monthly revenue could vary depending on the actual delivery of impressions throughout the contract term. These contracts are typically based on cost per thousand (“CPM”) rates and number of impressions served due to traffic volume and the specific ad campaign. For CPA offers, the consideration promised is variable based on a revenue share rate, and/or based on the number of actions delivered per the agreement. As such, the Company recognizes all actual advertising revenues from impressions or actions delivered on a monthly basis rather than estimating revenue at the beginning of the period. The Company has transactions with several partners that qualify for principal agent considerations. The Company recognizes revenue, net of amounts retained by the third-party partners, pursuant to revenue sharing agreements with advertising networks. The form of the agreements is such that the Company provides services in exchange for a fee. The Company determines only the fee for providing its services to advertising agencies and has no latitude in establishing prices with third party advertisers. In instances where the Company works directly with an advertiser, revenue is recognized on a gross basis. The Company is the primary obligor in arrangements made with direct advertisers, as there is no third-party facilitating or managing the sales process. The Company is solely responsible for determining price, product or service specifications, and which advertisers to use. The Company assumes all credit risk in the sales arrangements made with direct advertisers. The Company has determined that the performance obligation under the advertising revenue streams is recognized ratably over time utilizing the “Right to Invoice” practical expedient as customers simultaneously consume and receive benefits of the advertisement impressions. Deferred Revenue The Company records deferred revenue when the consideration for a good or service is received in advance of its performing the obligation.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash and cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests.
Restricted Cash	Restricted Cash Restricted cash consisted primarily of two certificates of deposit that are required as security for a letter of credit in connection with two of our facilities in California.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The Company extends credit on a non-collateralized basis to both U.S. and international customers. The Company extends credit to customers in the normal course of business and maintains an allowance for doubtful accounts resulting from the inability or unwillingness of customers to make required payments. Management determines the allowance for doubtful accounts by evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. The Company prepares an analysis of its ability to collect outstanding receivables that provides a basis for an allowance estimate for doubtful accounts. Based on this evaluation, the Company maintains an allowance for potential credit losses and for potential discounts based on historical experience and other information available to management. Discounts historically represent less than 1% of the related revenues. The fees associated with display advertising are often based on “impressions,” which are created when the ad is viewed. The amount of impressions often differs between non-standardized tracking systems, resulting in discounts on some payments. Difference between ad serving platforms with respect to impressions is primarily due to lag time between serving of advertising and other technical differences. Balance at Beginning of Period Additions, Costs and Expenses Deductions, Write-Offs Balance at End of the Period Allowance for Doubtful Accounts: Year Ended December 31, 2018 $ 527,958 $ 193,746 $ 338,125 $ 383,579 Year Ended December 31, 2017 $ 283,000 $ 304,306 $ 59,348 $ 527,958 Year Ended December 31, 2016 $ 133,000 $ 152,587 $ 2,587 $ 283,000
Business Acquisitions	Business Acquisitions The Company accounts for all business acquisitions at fair value and expenses acquisition costs as they are incurred. Any identifiable assets acquired and liabilities assumed are recognized and measured at their respective fair values on the acquisition date. If information about facts and circumstances existing as of the acquisition date is incomplete at the end of the reporting period in which a business acquisition occurs, the Company will report provisional amounts for the items for which the accounting is incomplete. The measurement period ends once the Company receives sufficient information to finalize the fair values; however, the period will not exceed one year from the acquisition date. In connection with certain acquisitions, the Company enters into agreements to pay additional amounts in cash on the achievement of certain performance measures for up to 1 year ending after the acquisition date. The Company measures this contingent consideration at fair value at the acquisition date and records such contingent consideration as a liability on the Company’s Consolidated Balance Sheets on the acquisition date. The fair value of each contingent consideration liability is remeasured at each reporting period with any change in fair value recognized as income or expense within operations in the Company’s consolidated statements of operations and comprehensive income (loss).
Goodwill	Goodwill Goodwill reflects the cost of an acquisition in excess of the fair values assigned to the identifiable net assets acquired. Goodwill is not amortized; rather, it is subject to a periodic assessment for impairment by applying a fair value based test. The Company performs its annual impairment test as of October 1st of a given calendar year, or more frequently if events or changes in circumstances indicate that the asset might be impaired. In prior years, the Company performed its annual goodwill impairment test as of December 31st of a given calendar year. This change was made to more align with the Company’s internal forecasting process. Goodwill is tested for impairment at the reporting unit level. The Company has determined that there are two reporting units, The Meet Group US and Lovoo. Accounting for acquisitions requires the Company to recognize, separately from goodwill, the assets acquired and the liabilities assumed at their acquisition-date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition-date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, the estimates are inherently uncertain and subject to refinement. The impairment model permits, and the Company utilizes, a simplified approach for determining goodwill impairment. In the first step, the Company evaluates the recoverability of goodwill by estimating the fair value of the Company’s reporting unit using multiple techniques, including an income approach using a discounted cash flow model and a market approach. Based on an equal weighting of the results of these two approaches, a conclusion of fair value is estimated. The fair value is then compared to the carrying value of the Company’s reporting unit. If the fair value of a reporting unit is less than its carrying value, the Company recognizes this amount as an impairment loss. Impairment losses, limited to the carrying value of goodwill, represent the excess of the carrying amount of goodwill over its implied fair value.
Intangible Assets	Intangible Assets Intangible assets consist of acquired trademarks, domain names, advertising customer relationships and mobile applications and are initially recorded at fair value. Amortization is recorded using an accelerated method based on projected revenues related to each asset over the respective estimated useful lives. Years Trademarks 5 to 10 Domain names 5 to 10 Mobile applications, purchased and internally developed 1 to 5 Customer relationships 1 to 10
Property and Equipment	Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Property and equipment acquired in business combinations is stated at fair value. The cost of improvements that extend the life of property and equipment are capitalized. All ordinary repair and maintenance costs are expensed as incurred. When capitalized assets are retired or sold, the cost and related accumulated depreciation or amortization is removed from the accounts, with any gain or loss reflected in operations. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows: Years Servers, computer equipment and software 1 to 3 Office furniture and equipment 3 to 5 Leasehold improvements 1 to 10 Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful life of the improvement or the lease term.
Long-Lived Assets and Intangibles with Finite Lives	Long-Lived Assets and Intangibles with Finite Lives Property and equipment and amortizable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an analysis is necessitated by the occurrence of a triggering event, then the Company compares the carrying amount of the asset with the estimated future undiscounted cash flows expected to result from the use of the asset. If the carrying amount of the asset exceeds the estimated expected undiscounted future cash flows, then the Company measures the amount of the impairment by comparing the carrying amount of the asset with its estimated fair value. Such analyses necessarily involve significant judgments and estimations on the part of the Company.
Lease Accounting	Lease Accounting The Company accounts for operating lease transactions by recording rent expense on a straight-line basis over the expected life of the lease, commencing on the date it gains possession of leased property. The Company includes tenant improvement allowances and rent holidays received from landlords and the effect of any rent escalation clauses as adjustments to straight-line rent expense over the expected life of the lease. Capital lease transactions are reflected as a liability at the inception of the lease based on the present value of the minimum lease payments or, if lower, the fair value of the property. Assets under capital leases are recorded in Property and Equipment, net on the consolidated balance sheets and depreciated in a manner similar to other Property and Equipment.
Fair Value Measurements	Fair Value Measurements The fair values of the Company’s financial instruments reflect the amounts that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The carrying amounts of the Company’s financial instruments of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and deferred revenue approximate fair value due to their short maturities. In addition, the Company carries its contingent consideration liabilities related to acquisitions at fair value. In accordance with the three-tier fair value hierarchy, the Company determined the fair value of its contingent consideration liabilities using the income approach with assumed discount rates and payment probabilities. The income approach uses Level 3, or unobservable inputs as defined under the accounting guidance for fair value measurements. On December 31, 2017 , the Company’s contingent consideration liability had a fair value of $5.0 million . The Company paid the full amount of the contingent consideration in April 2018. See Note 2— Acquisitions for more information regarding the Company’s contingent consideration liabilities. As part of the Lovoo Acquisition, the Company amended and restated its term loan and revolving credit facility. The Company carries a term loan facility with an outstanding balance of $36.9 million and $56.3 million at December 31, 2018 and 2017 , respectively. The outstanding balance as of December 31, 2018 approximates fair value due to the variable market interest rates and relatively short maturity associated with the Term Loan Facility. See Note 7— Long-Term Debt for more information regarding the Company’s credit facilities. The Company leases certain fixed assets under capital leases that expire in 2021. The capital leases are for the Company's data centers, printers and other furniture in the Company's German offices. The outstanding balance approximates fair value due to the relatively short maturities associated with these capital leases for the years ended December 31, 2018 and 2017 . The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the Financial Accounting Standards Board’s (“FASB”) fair value measurement guidance (ASU 2011-04), the Company is measuring the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. In 2017, the Company entered into an interest rate swap, interest rate cap and a cross-currency interest rate swap.
Foreign Currency	Foreign Currency The functional currency of our foreign subsidiaries is the local currency. The financial statements of these subsidiaries are translated to U.S. dollars using period-end rates of exchange for assets and liabilities and average quarterly rates of exchange for revenues and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Net gains and losses resulting from foreign exchange transactions are included in other income (expense).
Net Income (Loss) Per Share	Net Income (Loss) per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants using the average market prices during the period.
Significant Customers and Concentration of Credit Risk	Significant Customers and Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, and accounts receivable. The Company invests its excess cash in high-quality, liquid money market funds maintained by major U.S. banks and financial institutions. The Company has not experienced any losses on its cash equivalents. The Company performs ongoing credit evaluations of its customers and generally does not require collateral.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In the event that the Company determines that it will not be able to realize its deferred income tax assets in the future in excess of its net recorded amount, the Company will make an adjustment to the valuation allowance, which will increase the provision for income taxes. The Tax Cuts and Jobs Act (“Tax Act”) was enacted on December 22, 2017, most provisions of which became effective in 2018. The Tax Act made substantial changes to U.S. taxation of corporations, including lowering the U.S. federal corporate income tax rate from 35% to 21% and instituting a territorial tax system, along with a one-time tax on accumulated foreign earnings. The effect on deferred tax assets and liabilities of a change in law or tax rates is recognized in income in the period that includes the enactment date. The Company has adopted a policy with respect to the IRC Sec. 162(m) limiting deductions for compensation expense in excess of $1 million for certain high paid employees that it considered stock based compensation as being earned first in determining whether any deferred tax asset will be limited. For every tax-paying component and within each tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single net noncurrent asset or liability. The Company’s income tax returns are periodically audited by U.S. federal, state and local, and foreign tax authorities. These audits include questions regarding the Company’s tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. At any one time, multiple tax years are subject to audit by the various tax authorities. In evaluating the tax benefits associated with the Company’s various tax filing positions, the Company records a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. A number of years may elapse before a particular matter, for which a liability has been established, is audited and effectively settled. The Company adjusts its liability for unrecognized tax benefits in the period in which it determines the issue is effectively settled with the tax authorities, the statute of limitations expires for the relevant taxing authority to examine the tax position or when more information becomes available.
Product Development and Content Costs	Product Development and Content Costs Product development and content costs, including costs incurred in the classification and organization of listings within our websites, salaries, benefits, and stock-based compensation, utility charges, occupancy and support for our offsite technology infrastructure, bandwidth and content delivery fees, broadcaster rewards, app store fees, and development and maintenance costs, are charged to expense as incurred.
Stock-Based Compensation	Stock-Based Compensation The fair value of stock options is estimated on the grant date using the Black-Scholes option pricing model, based on weighted average assumptions. Expected volatility is based on historical volatility of our common stock. The Company has elected to use the simplified method described in the Securities and Exchange Commission Staff Accounting Bulletin Topic 14C to estimate the expected term of employee stock options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The value of restricted stock awards are determined using the fair value of the Company’s common stock on the date of grant. The fair value of performance share awards are estimated using a Monte-Carlo simulation model utilizing several key assumptions including expected Company and Russell 2000 Peer Group share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The Company accounts for forfeitures as they occur. Compensation expense is recognized on a straight-line basis over the requisite service period of the award.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes all changes in stockholders’ equity during a period from non-owner sources. Comprehensive income (loss) consists of unrealized gains (losses) on derivative financial instruments, reclassifications of gains (losses) on derivative financial instruments, and foreign currency translation adjustments which are added to net income (loss) to compute total comprehensive income (loss).
Contingencies	Contingencies The Company accrues for contingent obligations, including legal costs and restructuring costs, when the obligations are probable and the amount can be reasonably estimated. As facts concerning contingencies become known the Company reassess its position and makes appropriate adjustments to the consolidated financial statements. Estimates that are particularly sensitive to future changes include those related to tax, legal, and other regulatory matters that are subject to change as events evolve and additional information becomes available.
Segment Reporting	Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the chief executive officer. The Company and the chief executive officer view the Company’s operations and manage its business as one reportable segment with two operating segments, which are also its reporting units, The Meet Group US and Lovoo.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months . The lease liability represents the present value of minimum lease payments as of the adoption date. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2018, and annual and interim periods thereafter, with early adoption permitted. A modified retrospective transition approach is an option for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842). ASU 2018-11 adds an optional transition method allowing entities to apply the new lease accounting rules through a cumulative-effect adjustment to the opening balance of retained earnings in the initial year of adoption. The Company has established a process to identify a complete population of its leases, including the review of various contracts to identify whether such arrangements convey the right to control the use of an identified asset. The Company has additionally implemented new processes and controls to assist with the adoption of this standard. The Company will adopt this standard effective January 1, 2019 utilizing certain transition practical expedients added by the FASB which eliminate the requirement that entities apply the new lease standard to the comparative periods presented in the year of adoption. The Company will elect the package of practical expedients permitted under the new standard which, among other things, allows the Company to not reassess the lease classification, the lease identification and the initial direct costs for any existing leases. Further, as permitted by the standard, the Company will make an accounting policy election not to record ROU assets or lease liabilities for leases with an initial term of 12 months or less. Instead, consistent with legacy accounting guidance, the Company will recognize payments for such leases in the statement of operations on a straight-line basis over the lease term. Upon adoption on January 1, 2019, the Company estimates this standard will result in the recognition of additional assets and liabilities on its balance sheet of $3.3 million each. The Company does not believe that the new standard will have a material impact on its results of operations or cash flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , providing additional guidance on several cash flow classification issues, with the goal of the update to reduce the current and potential future diversity in practice. The amendments in this update are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The amendment allows an entity to elect to reclassify the stranded tax effects resulting from the change in income tax rate from the Tax Cuts and Jobs Act (“Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments in this update are effective for fiscal years beginning after on December 15, 2018 and interim periods within those fiscal years. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement . This amendment removes, modifies, and makes certain additions to the disclosure requirements on fair value measurement. The amendments in this update are effective for fiscal years beginning after on December 15, 2019 and interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this new standard will have on its consolidated financial statements.
