Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Nature of Operations
	Angie’s List, Inc. (collectively with its wholly owned subsidiaries, the "Company") operates a national local services consumer review service and marketplace where consumers can research, shop for and purchase local services for critical needs, such as home, health and automotive services, as well as rate and review the providers of these services. Ratings and reviews, which are available only to the Company’s members, assist members in identifying and hiring the best provider for their local service needs. Membership subscriptions are sold on a monthly, annual and multi-year basis. The consumer rating network “Angie’s List” is maintained and updated based on consumer feedback. The Company also sells advertising in its monthly publication, on its website and mobile application and through its call center to service providers that meet certain ratings criteria. In addition, the Company’s e-commerce marketplace offerings provide consumers with the opportunity to purchase services directly through the Company's marketplace from highly-rated service providers. The Company’s services are provided in markets located across the continental United States.
	Operating Segments
	Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one operating segment.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
	Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes as well as the disclosure of contingent assets and liabilities and reported revenue and expenses. Actual results could differ from those estimates, but management does not believe such differences will materially affect Angie’s List, Inc.’s financial position or results of operations. The consolidated financial statements reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly present the results for the periods.
	Reclassification of Prior Year Presentation
	Certain prior year amounts were reclassified for consistency with the current period presentation. These reclassifications did not materially impact the consolidated financial statements.
	Revenue Recognition and Deferred Revenue
	The Company recognizes revenue when all of the following conditions are met: there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of fees is reasonably assured and the amount of fees to be paid by the customer is fixed or determinable.
	Membership Revenue
	Revenue from the sale of membership subscriptions is recognized ratably over the term of the associated subscription. Prior to 2014, the Company generally received a one-time, nonrefundable enrollment fee at the time a member joined. Enrollment fees are deferred and recognized on a straight-line basis over an estimated average membership life of 80 months for annual or multi-year members and 13 months for monthly members, which is based on historical membership experience. The Company reviews the estimated average membership lives on an annual basis, or more frequently if circumstances change. Changes in member behavior, performance, competition and economic conditions may cause attrition levels to change, which could impact the estimated average membership lives. The Company discontinued charging nonrefundable enrollment fees in 2014.
	Service Provider Revenue
	Revenue from the sale of advertising in the Company’s Angie’s List Magazine publication is recognized in the month in which the publication is published and distributed. Revenue from the sale of website, mobile and call center advertising is recognized ratably over the time period the advertisements run. Revenue from e-commerce vouchers is recognized on a net basis when the voucher is delivered to the purchaser. While the Company is not the merchant of record with respect to its customers for these transactions, it does offer customers refunds in certain circumstances. Revenue from e-commerce transactions is recorded net of a reserve for estimated refunds. The Company’s e-commerce revenue was $27,133, $22,062 and $14,475 for 2014, 2013 and 2012, respectively.
	Deferred Revenue
	Deferred revenue includes the unamortized portion of revenue associated with membership and service provider fees for which the Company received payment in advance of services or advertising to be provided. Deferred revenue is recognized as revenue when the related services or advertising are actually provided.
	Cash and Cash Equivalents
	The Company maintains its cash in bank deposit accounts and money market funds with contractual maturities of three months or less, which, at times, may exceed federally insured limits. The Company also classifies as cash and cash equivalents any investments in corporate bonds or certificates of deposit with original maturities of three months or less. To date, the Company has not incurred any losses in these accounts.
	Short-Term Investments
	Short-term investments consist of corporate bonds and certificates of deposit with maturities of more than 90 days but less than one year, all of which are designated as held-to-maturity investments and recorded at amortized cost, adjusted for amortization of premiums to maturity computed under the effective interest method, in the consolidated balance sheets. Amortization and interest income from held-to-maturity investments are included in interest expense, net, in the consolidated statements of operations. The Company’s objective with respect to these investments is to earn a higher rate of return on funds that are otherwise not anticipated to be required to meet liquidity needs in the near term while maintaining a low level of investment risk with the positive intent and ability to hold these investments to maturity. Short-term investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may be impaired. As of December 31, 2014 and 2013, the Company held $24,268 and $21,055, respectively, in short-term investments with no material unrealized gains or losses in these accounts in either year then ended.
	Accounts Receivable
	Accounts receivable is stated at the amount billed to service providers, less an estimated allowance for doubtful accounts. The Company performs ongoing credit evaluations and generally requires no collateral from service providers. Management reviews individual accounts as they become past due to determine collectability. The Company's allowance for doubtful accounts balance is adjusted periodically based on management’s consideration of past due accounts. Individual accounts are charged against the allowance when all reasonable collection efforts are exhausted.
	The changes in the Company's allowance for doubtful accounts balances during the years ended December 31, 2014, 2013 and 2012 were as follows:
		Year Ended December 31,
		2014			2013			2012
	Beginning balance	$	1,107		$	922		$	535
	Additions, net of recoveries	5,028			3,773			1,955
	Deductions	(4,484		)	(3,588		)	(1,568		)
	Ending balance	$	1,651		$	1,107		$	922
	Property, Equipment and Software
	Assets recorded as property, equipment and software are stated at cost and depreciated over their respective estimated useful lives. The Company also capitalizes certain costs related to website and software acquisition and development for internal use, including the associated interest costs incurred during development. Construction in progress is related to the construction or development of property, equipment and software that is not ready for its intended use and therefore not yet placed in service. The Company’s estimated useful lives for property, equipment and software range from 3 to 25 years. Depreciation is computed using the straight-line method. Repairs and routine maintenance are charged to expense as incurred.
	In accordance with authoritative guidance, the Company begins to capitalize website and software development costs for internal use when preliminary development efforts are successfully completed and technological feasibility is established. Costs incurred prior to the establishment of technological feasibility, together with costs incurred for related training and maintenance, are expensed as incurred and recorded in product and technology expense within the consolidated statements of operations.
	During 2014, the Company began capitalizing a portion of the interest on funds borrowed as part of its capitalized website and software development costs, primarily related to ongoing development around internal use software. For the year ended December 31, 2014, total interest costs incurred amounted to $2,613, of which $1,410 was capitalized as construction in progress for website and software development costs. No interest costs were capitalized for the years ended December 31, 2013 or 2012.
	Goodwill
	Goodwill is not amortized and is instead reviewed for impairment, at a minimum, on an annual basis as of December 31, or more frequently should an event or circumstance occur that indicates the carrying amount of goodwill may be impaired. If goodwill is considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the goodwill exceeds its fair market value. To date, no impairment of goodwill has been identified or recognized.
	Data Acquisition Costs
	Data acquisition costs consist of external costs related to acquiring consumer reports on service providers. These reports are used by the Company to provide its members with feedback on service providers. Amortization is computed using the straight-line method over the period which the information is expected to benefit the Company’s members, which is estimated to be three years. The capitalized costs are included in intangible assets in the consolidated balance sheets, and the amortized expense is reflected within operations and support expense in the consolidated statements of operations.
	Long-Lived Assets
	Long-lived assets, including property, equipment and software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by the related asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair market value of the assets. A one-time, long-lived asset impairment charge was recorded during the fourth quarter of the current year related to the Company's abandonment of certain capitalized website and software development assets and is discussed in more detail in Note 5, "Property, Equipment and Software," of this Form 10-K. To date, there have been no other adjustments to the respective carrying values of the Company's long-lived assets.
	Deferred Financing Fees
	As a result of its entry into a new financing agreement in September 2014, the Company incurred financing costs that were capitalized as a deferred financing fee asset and are being amortized into interest expense over the term of the credit facility. In connection with the extinguishment of the Company's previous loan and security agreement during the course of the aforementioned current year financing transaction, the Company expensed the remaining unamortized portion of the capitalized deferred financing fees associated with the previous loan and security agreement, and the related amount is included in the loss on debt extinguishment within the consolidated statements of operations.
	Fees Paid to Lender
	The Company incurred financing costs in the form of fees paid directly to the lender during the completion of its September 2014 long-term debt financing transaction. In accordance with the applicable authoritative guidance, these fees were recorded as a contra liability offsetting the gross term loan balance. The fees paid to lender contra liability is being amortized to interest expense on a straight-line basis over the term of the related debt. The Company's long-term debt balance is reported net of the remaining unamortized fees paid to the lender within the consolidated balance sheets.
	Leases
	The Company leases office space pursuant to long-term noncancellable operating leases expiring through 2020. Rent expense is recognized on a straight-line basis over the expected lease term. Certain of the Company's leases contain provisions for tenant improvement allowances, which are recorded as a deferred rent liability and amortized over the term of the associated lease as an offset to rent expense each period. Leasehold improvements are capitalized to property, equipment and software and depreciated on a straight-line basis over the corresponding estimated useful lives.
	Sales Commissions
	Commissions expense from the sale of service provider advertisements is recognized ratably over the term of the associated advertisement. The Company defers the recognition of commission expense until such time as the revenue related to the customer contract for which the commission was paid is recognized. Deferred commissions for each contract are amortized to expense in a manner consistent with how revenue is recognized for such contract, resulting in straight-line recognition of expense over the contractual term. Unamortized commission expense of $11,378 and $9,395 as of December 31, 2014 and 2013, respectively, is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
	Marketing Expense
	Marketing expense consists of national television, radio and print advertising as well as online digital advertising. The Company expenses all advertising costs as incurred.
	Stock-Based Compensation
	The Company accounts for stock-based compensation using the fair value recognition provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 718, Stock Compensation. For its awards of stock options, the Company recognizes stock-based compensation expense in an amount equal to the fair market value on the grant date of the respective award. The Company recognizes this expense, net of estimated forfeitures, on a straight-line basis over the requisite service period. The fair value of awards granted is estimated at the date of grant using the Black-Scholes option-pricing model with the historical weighted-average assumptions outlined in Note 11, "Stock-Based Compensation," of this Form 10-K.
	Loss on Debt Extinguishment
	The penalties, additional interest and other fees and expenses incurred in connection with the prepayment of the Company’s previous debt facility in September 2014, together with the amounts related to the write-off of the previous deferred financing fees and recognition of the remaining warrant interest expense under the prior debt facility, are included within the loss on debt extinguishment contained in the consolidated statement of operations for the year ended December 31, 2014.
	Income Taxes
	The Company is subject to corporate-level federal and state income taxes at prevailing corporate rates and accounts for income taxes and the related accounts using the asset and liability method in accordance with ASC 740, Income Taxes. Under this method, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between the book and tax basis of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted rates in effect for the years in which the differences are expected to reverse and recognizes the effect of a change in enacted rates in the period of enactment. After determining the total amount of deferred tax assets, the Company determines whether it is more likely than not that some portion of the deferred tax assets will not be realized. If the Company determines that a deferred tax asset is not likely to be realized, a valuation allowance will be established against that asset to record it at its expected realizable value. The Company establishes assets and liabilities for uncertain positions taken or expected to be taken in income tax returns using a more-likely-than-not recognition threshold. The Company includes in income tax expense any interest and penalties related to uncertain tax positions.
	Sales and Use Tax
	Sales and use tax expenses are included within operations and support expense in the consolidated statements of operations. The Company does not separately collect sales and use taxes from its members.
	Subsequent Events
	The Company evaluated subsequent events through the date these consolidated financial statements were issued.
	Recent Accounting Pronouncements
	In January 2015, the FASB issued Accounting Standards Update No. 2015-01: Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items ("ASU 2015-01"). The objective of this Update is to simplify the income statement presentation requirements in Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, by eliminating the concept of extraordinary items from U.S. GAAP. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. ASU 2015-01 will be effective for the Company in fiscal year 2016, and prospective application is permitted, with the lone required transition disclosure, if applicable, being the nature and the amount of an item included in income from continuing operations after adoption that adjusts an extraordinary item previously classified and presented before the date of adoption. The Company is currently assessing the future impact of this update to the consolidated financial statements.
In August 2014, the FASB issued Accounting Standards Update No. 2014-15: Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). The update sets forth a requirement for management to evaluate whether there are conditions and events that raise substantial doubt about an entity's ability to continue as a going concern, a responsibility that did not previously exist in U.S. GAAP. The amendments included in this update require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 will be effective for the Company in fiscal year 2016. The Company is currently assessing the future impact of this update to the consolidated financial statements.
In May 2014, the FASB issued Accounting Standards Update No. 2014-09: Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). The update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." The update also requires significantly expanded disclosures related to revenue recognition. ASU 2014-09 will be effective for the Company in fiscal year 2017. The Company is currently evaluating the future impact and method of adoption of this update with respect to the consolidated financial statements.
In July 2013, the FASB issued Accounting Standards Update No. 2013-11: Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). An entity is required to present unrecognized tax benefits as a decrease in a net operating loss, similar tax loss or tax credit carryforward if certain criteria are met. The determination of whether a deferred tax asset is available is based on the unrecognized tax benefit and the deferred tax asset that exists at the reporting date and presumes disallowance of the tax position at the reporting date. The guidance eliminates the diversity in practice in the presentation of unrecognized tax benefits but does not alter the way in which entities assess deferred tax assets for realizability. ASU 2013-11 became effective and was adopted by the Company in fiscal year 2014 with no material impact to the consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	Whenever possible, quoted prices in active markets are used to determine the fair value of the Company's financial instruments. The Company's financial instruments are not held for trading or other speculative purposes. The estimated fair value of financial instruments was determined using available market information and appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
	Fair Value Hierarchy
	Fair value is based on the price 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. In accordance with ASC 820, Fair Value Measurement, the Company categorized the financial assets and liabilities that are adjusted to fair value based on the priority of the inputs to the valuation technique, following the three-level fair value hierarchy prescribed by ASC 820, as follows:
	Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
	Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.
	Level 3: Unobservable inputs are used when little or no market data is available.
	Valuation Techniques
	The Company’s money market fund investments are classified as cash equivalents within Level 1 of the fair value hierarchy on the basis of valuations using quoted market prices. As many fixed income securities do not trade daily, fair values are often derived using recent trades of securities with similar features and characteristics. When recent trades are not available, pricing models are used to determine these prices. These models calculate fair values by discounting future cash flows at estimated market interest rates. Such market rates are derived by calculating the appropriate spreads over comparable U.S. Treasury securities, based on the credit quality, industry and structure of the asset. Typical inputs and assumptions to pricing models include, but are not limited to, a combination of benchmark yields, reported trades, issuer spreads, liquidity, benchmark securities, bids, offers, reference data and industry and economic events. The Company’s fixed income corporate bond investments and certificates of deposit with fixed maturities are valued using recent trades or pricing models and are therefore classified within Level 2 of the fair value hierarchy.
	Recurring Fair Value Measurements
	There were no movements between fair value measurement levels of the Company’s cash equivalents and investments during 2014 or 2013, and there were no material unrealized gains or losses in these accounts as of December 31, 2014 or 2013.
	The following tables summarize the Company's financial instruments at fair value based on the fair value hierarchy for each class of instrument as of December 31, 2014 and 2013:
				Fair Value Measurement at December 31, 2014 Using
		Carrying Value at December 31, 2014		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable		Significant Unobservable

	Corporate bonds	7,305		—		7,303		—
	Total assets	$	21,710	$	655	$	21,037	$	—
	The carrying amounts of the term loans approximate fair value, using Level 2 inputs, as these borrowings bear interest at variable (market) rates at December 31, 2014 and 2013.
	Non-Recurring Fair Value Measurements
	The Company has certain assets that are measured at fair value on a non-recurring basis under circumstances and events, including those described in Note 5, "Property, Equipment and Software," and Note 6, "Goodwill and Amortizable Intangible Assets," that are adjusted to fair value only when the carrying values are more than the fair values. The categorization of the framework used to price the assets in the event of an impairment, such as the current year non-cash long-lived asset impairment charge (see Note 5 for additional information), is considered a Level 3 measurement due to the subjective nature of the unobservable inputs used to determine the fair value.
	Assets and liabilities acquired in business combinations are recorded at their fair value as of the date of acquisition. Refer to Note 6 for the fair values of assets acquired and liabilities assumed in connection with the prior year acquisition of substantially all the assets of SmartHabitat (“BrightNest”).
	The carrying amounts of accounts receivable and accounts payable reported in the consolidated balance sheets approximate fair value.

	During the fourth quarter of 2014, the Company recorded a $1,778 one-time, non-cash long-lived asset impairment charge related to the abandonment of certain capitalized website and software development assets. The impairment was recorded as a result of the Company's decision to abandon certain aspects of its e-commerce order fulfillment functionality. The Company evaluated the ongoing value and specific costs incurred to date with respect to the functionality and ultimately identified a long-lived asset impairment charge in the aforementioned amount that was recorded in the product and technology expense line within the consolidated statement of operations for the year ended December 31, 2014.

	The Company has goodwill as well as certain amortizable intangible assets consisting of data acquisition costs, a member list, content, core technology and other intangible assets related to the purchase of a website domain name. The goodwill and amortizable intangible asset balances reflect the goodwill, member list, content and core technology acquired during the August 2, 2013 acquisition of substantially all the assets of BrightNest for a purchase price of $2,650, inclusive of $1,920 in acquired intangible assets and goodwill of $730. The purchase price consisted of $2,150 in cash paid at closing and an additional $500 that was paid during 2014 as contingent consideration on the one-year anniversary of the closing of the acquisition. Revenues and expenses related to BrightNest, which are not material, are included in the consolidated results of operations from the date of acquisition.
	Amortization on the intangible assets is computed using the straight-line method over the estimated lives of the assets, which are six years and three years, respectively, for the member list and other intangible assets, including content, core technology and data acquisition costs. Amortizable intangible assets as of December 31, 2014 and 2013 are as follows:

	Total long-term debt, net	$	58,854		$	14,918
	On September 26, 2014, the Company entered into a financing agreement for a $60,000 term loan and a $25,000 delayed draw term loan.
	Amounts outstanding under the financing agreement bear interest at a per annum rate, at the option of the Company, equal to (i) the LIBOR rate for the interest period in effect, subject to a floor of 0.5%, plus 6.75% or (ii) the reference rate, which is based on the prime rate as published by the Wall Street Journal, subject to a floor of 3.25%, plus 5.75%. The financing agreement requires monthly interest-only payments on the first business day of each month until maturity on any principal amounts outstanding under either debt facility. The financing agreement obligates the Company to make quarterly principal payments on the term loan of $750 on the last day of each calendar quarter, commencing with the quarter ending September 30, 2016, and to repay the remaining balance of the term loan at maturity. The Company is required to make principal payments on the outstanding balance of the delayed draw term loan equal to 1.25% of the amount of such loan funded at or prior to the last day of each calendar quarter, commencing with the quarter ending September 30, 2016, and to repay the remaining outstanding balance of the delayed draw term loan at maturity. From the effective date of the financing agreement through September 26, 2017, the Company is also required to pay a commitment fee equal to 0.75% per annum of the unborrowed amounts of the delayed draw term loan.
	The Company may prepay the amounts outstanding under the financing agreement at any time and is required to prepay the loans with (i) the net proceeds of certain asset sales, issuances of debt or equity, and certain casualty events, and (ii) up to 50% of consolidated excess cash flow, as defined in the financing agreement, for each fiscal year during the term of the financing agreement, commencing with the year ended December 31, 2015. The Company must pay a 1% premium on prepayments made on or before September 26, 2015, subject to certain exceptions set forth in the financing agreement. The Company’s obligations under the financing agreement are guaranteed by each of its subsidiaries and are secured by first priority security interests in all of their respective assets and a pledge of the equity interests of the Company’s subsidiaries. The term loan and the delayed draw term loan mature on September 26, 2019. As of December 31, 2014, the Company had $58,854 in outstanding borrowings, net of fees paid to the lender of $1,146, under the term loan and availability of $25,000 under the delayed draw term loan.
	The financing agreement contains various restrictive covenants, including restrictions on the Company's ability to dispose of assets, make acquisitions or investments, incur debt or liens, make distributions to stockholders or repurchase outstanding stock, enter into related-party transactions and make capital expenditures, other than upon satisfaction of the conditions set forth in the financing agreement. The Company is also required to comply with certain financial covenants, including minimum consolidated EBITDA as defined in the financing agreement, minimum liquidity, maximum consolidated capital expenditures and minimum membership revenue. Upon an event of default, which includes certain customary events such as, among other things, a failure to make required payments when due, a failure to comply with covenants, certain bankruptcy and insolvency events, defaults under other material indebtedness, or a change in control, the lenders may accelerate amounts outstanding, terminate the agreement and foreclose on all collateral. The Company's capital expenditures in the fourth quarter of 2014 exceeded the maximum allowable amount under the financial covenant set forth in the financing agreement related to consolidated capital expenditures, and as such, the Company was not in compliance with this covenant at December 31, 2014. The Company remedied the noncompliance by obtaining a waiver of non-compliance under the financing agreement from the lender. The Company was in compliance with all other financial and non-financial covenants at December 31, 2014.
	The Company used a portion of the proceeds from the term loan to pay bank and lender fees and transaction costs associated with the new financing agreement. Furthermore, the Company also used a portion of the term loan proceeds to simultaneously repay in full the outstanding balance of $15,000 on the Company’s previous term loan, thereby terminating the related loan and security agreement. The Company incurred approximately $192 in incremental interest and fees as a result of the prepayment, including additional interest of $105 and prepayment penalties of $75. The prepayment penalties, additional interest and other fees and expenses associated with the prepayment of the Company’s previous loan and security agreement, together with $221 related to the write-off of the previous deferred financing fees and $45 for the recognition of the remaining warrant interest expense under the prior debt facility, are included within the loss on debt extinguishment of $458 contained in the consolidated statement of operations for the year ended December 31, 2014.
	As a result of its entry into the new financing agreement in September 2014, the Company incurred financing costs of $1,957 that were capitalized as a deferred financing fee asset and are being amortized into interest expense over the term of the credit facility. Deferred financing fees, net of accumulated amortization, totaled $1,854 and $397 at December 31, 2014 and 2013, respectively. Amortization expense of $279, $237 and $232 is included in interest expense in the consolidated statements of operations for 2014, 2013 and 2012, respectively.
	On August 31, 2011, the Company entered into a loan and security agreement that provided for a $15,000 term loan and a $15,000 revolving credit facility, scheduled to mature in August 2015. The term loan bore interest at a per annum rate equal to the greater of (i) the current cash interest rate of LIBOR plus 10% or (ii) 10.5% and required monthly interest-only payments until maturity. The revolving credit facility required monthly interest-only payments on advances, bearing interest at a per annum rate equal to LIBOR plus 5%. In addition, when less than 50% of the revolving credit facility was drawn, the Company was required to pay a non-usage charge of 0.50% per annum of the average unused portion of the credit facility. The term loan contained a provision for penalties upon early prepayment, and together with the revolving credit facility, was secured by substantially all of the Company’s assets. The loan and security agreement contained various restrictive covenants, including restrictions on the Company’s ability to dispose of assets, make acquisitions or investments, incur debt or liens, make distributions to stockholders or enter into certain types of related-party transactions. The Company was also required to comply with certain financial covenants, including a minimum asset coverage ratio, and non-financial covenants. The Company was in compliance with all financial and non-financial covenants under the previous loan and security agreement at December 31, 2013, at which point in time the Company had $14,918 in outstanding borrowings under the term loan and available credit of $15,000 under the revolving credit facility. The Company retired this debt on September 26, 2014.

Additionally, the Company refinanced its long-term debt during the third quarter of 2014, resulting in the retirement of the previous term loan and revolving credit facility and the issuance of a new term loan and delayed draw term loan, both of which are scheduled to mature on September 26, 2019. See Note 8, "Debt and Credit Arrangements," for additional information regarding the financing transaction.
	Operating Leases
	The Company leases office space pursuant to long-term noncancellable operating leases expiring through 2020. The Company is responsible for paying its proportionate share of the actual operating expenses and real estate taxes under certain of these lease arrangements.
	As of December 31, 2014, the estimated future minimum lease payments under long-term noncancellable operating leases for each of the next five years and thereafter are as follows:

	Rent expense under the Company's operating leases totaled $1,643, $910 and $1,381 in 2014, 2013 and 2012, respectively.
	Legal Matters
	From time to time, the Company has or may become party to litigation incident to the ordinary course of business. The Company assesses the likelihood of any adverse judgments or outcomes with respect to these matters and determines loss contingency assessments on a gross basis after assessing the probability of incurrence of a loss and whether a loss is reasonably estimable. In addition, the Company considers other relevant factors that could impact its ability to reasonably estimate a loss. A determination of the amount of reserves required, if any, for these contingencies is made after analyzing each matter. The Company’s reserves may change in the future due to new developments or changes in strategy in handling these matters. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of the matters listed below will not have a material adverse effect on its business, consolidated financial position, results of operations or cash flows. Regardless of the outcome, litigation can adversely impact the Company as a result of defense and settlement costs, diversion of management resources and other factors.
	Fritzinger v. Angie’s List, Inc. On August 14, 2012, a lawsuit seeking class action status was filed against the Company in the U.S. District Court for the Southern District of Indiana (the “Court”). The lawsuit alleges claims of breach of contract and unjust enrichment, alleging that the Company automatically renews membership fees at a higher rate than customers are led to believe, breaching their membership agreements. On September 22, 2014, the Court issued an Order approving the parties' proposed settlement terms. Under the settlement terms, total cash payments to the class will be $107. Additionally, 734,299 class members will receive a one month Angie's List membership, and 353,130 class members will receive a five dollar e-commerce voucher. The Company estimates that attorney's fees and litigation fees will amount to $875. The Company recorded a $4,000 legal accrual related to the settlement at December 31, 2013. Based on the terms of the settlement approved by the Court, including payments made under the settlement to date, the Company's remaining legal settlement liability is $2,183 as of December 31, 2014. The Company believes this amount represents the best estimate of its remaining liability with respect to this litigation.
	Putative Securities Class Action Litigation. On December 23, 2013, the first of two putative securities class action complaints was filed in the United States District Court for the Southern District of Indiana, naming the Company and various of its current and former directors and officers as defendants. The first complaint is styled as Baron v. Angie’s List, Inc. et al., 1:13-cv-2032. On January 9, 2014, the second putative securities class action was filed in the United States District Court for the Southern District of Indiana. The second complaint is styled as Bartolone v. Angie’s List, Inc., et al, 1:14-cv-0023. Both complaints allege that the defendants violated Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”) by making material misstatements in and omitting material information from the Company’s public disclosures concerning the Company’s business prospects. On June 16, 2014, the Court consolidated the two cases and appointed United Food & Commercial Workers Local 464A Pension Fund as lead plaintiff (“Local 464A”). On August 29, 2014, Local 464A filed its consolidated Amended Complaint (the "Amended Complaint"). The Amended Complaint alleges that Angie's List made material misrepresentations and omissions regarding its paid membership model ("PPM"). The defendants filed a motion to dismiss the Amended Complaint, which has yet to be ruled upon by the Court.
	Korda v. Oesterle, et al. On January 3, 2014, a derivative complaint was filed in the United States District Court for the Southern District of Indiana, naming the Company’s Board of Directors and various current and former officers as individual defendants. The Company is named as a nominal defendant. The complaint is styled as Korda v. Oesterle, et al., 1:14-cv-00004. The complaint asserts that the individual defendants breached their fiduciary duty based on their knowledge that the Company’s public statements during 2013 concerning the Company’s business prospects were allegedly misleading. The complaint also alleges that certain defendants breached their fiduciary duty by selling shares of Angie’s List common stock between December 2012 and December 2013. The plaintiff asks for unspecified amounts in damages, interest and costs as well as ancillary relief. The Court issued an order staying the action pending a ruling on the motion to dismiss Local 464A’s Amended Complaint in the Putative Securities Class Action Litigation described above.
	Clark v. Oesterle, et al. On October 17, 2014, a derivative complaint was filed in the Court of Chancery of the State of Delaware, naming members of the Company’s Board of Directors and various current and former officers as individual defendants. The Company is named as a nominal defendant. The complaint is styled as Clark v. Oesterle, et al., C.A. No. 10255. The complaint alleges that the individual defendants breached their fiduciary duties by making misleading representations regarding, among other things, the Company’s business prospects. The complaint also alleges that certain individual defendants breached their fiduciary duties by selling shares of Angie’s List common stock between February 2013 and October 2013. The plaintiff asks for unspecified amounts in damages, interest and costs as well as ancillary relief. The Court issued an order staying the action pending a ruling on the motion to dismiss Local 464A’s Amended Complaint in the Putative Securities Class Action Litigation described above.

	In April 2010, the Company adopted an Omnibus Incentive Plan (the Incentive Plan) in order to provide an incentive to certain executive officers, personnel and directors. The Incentive Plan was amended and restated effective August 2011, increasing the number of shares issuable to 5,090,496. In March 2012, October 2013 and July 2014, additional shares of stock were reserved for issuance, bringing the total available shares issuable to 13,753,277. As of December 31, 2014, there were 11,855,060 shares of common stock reserved under the Incentive Plan, of which 6,416,163 shares remained available for future grants.
	Stock Options
	Stock options are awarded with an exercise price equal to the market price on the date of grant. The contractual terms for options expire ten years from the grant date and generally vest over a period of four years. The fair value of options on the date of grant is amortized on a straight-line basis over the requisite service period.
	A summary of stock option activity under the Incentive Plan as of December 31, 2014 and 2013 and changes during the periods then ended are as follows:

	The fair value of awards granted is estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:
	Year of Grant	Risk-Free		Dividend		Expected		Volatility
		Interest		Yield		Term		Factor
		Rate
						(in years)
	2012	0.71%		0%		4.4		60.00%
	2013	1.02%		0%		4.9		57.00%
	2014	1.67%		0%		5		53.00%
	Expected volatility is based on historical volatilities for publicly traded common stock of comparable peer companies over the estimated expected life of the stock options. The expected term represents the period of time the stock options are expected to be outstanding. The dividend yield assumption is based on the fact that the Company does not have a history of issuing dividends and does not anticipate issuing dividends in the near term. The risk-free interest rate is based on yields of U.S. Treasury securities with maturities similar to the estimated expected term of the stock options.
	The weighted-average grant date fair value of options granted during 2014 and 2013 was $5.12 and $9.38 per share, respectively. The total intrinsic value of options exercised during 2014, 2013 and 2012 was $456, $7,376 and $297, respectively. The Company recognized stock-based compensation expense of $7,889, $4,064 and $2,943 in the consolidated statements of operations related to stock options in 2014, 2013 and 2012, respectively. As of December 31, 2014, total stock-based compensation expense related to non-vested options not yet recognized was $21,227, which will be recognized over the remaining weighted-average life of the awards, 2.87 years.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the consolidated financial statement amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. As management believes that it is more likely than not that the Company will not realize the full amount of its net deferred tax assets, the Company recorded a valuation allowance for the deferred tax assets as of December 31, 2014, 2013 and 2012, respectively.
	The provision for income taxes for the years ended December 31, 2014, 2013 and 2012 consisted of the following components:
		2014				2013				2012
	Current:
	U.S. federal	$	—			$	—			$	—
	State	40				34				—

	State	1				2				3
	Total deferred	11				6				5
	Provision for income taxes	$	51			$	40			$	5
	The reconciliation of income tax expense computed at the U.S. federal statutory rate to the Company’s effective tax rate for the years ended December 31, 2014, 2013 and 2012 is as follows:
		2014			2013			2012
	U.S. federal income tax rate	34	%		34	%		34	%
	State income taxes, net of federal benefit	(0.5	)%		6.4	%		5.7	%

	Equity compensation	(9.4	)%		(0.4	)%		—	%
	Other	(4.4	)%		(0.4	)%		(0.6	)%
	Effective income tax rate	(0.4	)%		(0.1	)%		0	%
	Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2014 and 2013 are as follows:
		2014				2013
	Deferred tax assets:
	Current:
	Deferred revenue	$	35,477			$	32,643

	Total net deferred tax liabilities	(14,798		)		(4,037		)
	Total net deferred tax liability	$	(181	)		$	(169	)
	As of December 31, 2014, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $128,328 and $158,856, respectively. These net operating losses include an unrealized benefit of approximately $6,056 related to share-based compensation that will be recorded in equity when realized. The net operating loss carryforwards will expire in future years, primarily beginning in 2027. The net operating losses may be subject to annual limitations of use under Internal Revenue Code Section 382. The Company files income tax returns in the U.S. federal jurisdiction and in various state jurisdictions. Income tax returns for the short year ended December 31, 2010 to present are open for examination in the federal jurisdiction and in significant state jurisdictions.
	A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. The Company does not benefit from its deferred tax assets based on the deferred tax liabilities related to goodwill that are not expected to reverse during the carryforward period. As this deferred tax liability would not reverse until some future indefinite period when the intangibles are either sold or impaired, any resulting temporary differences cannot be considered a source of future taxable income to support realization of the deferred tax assets.
	At December 31, 2014 and 2013, the Company did not have any material unrecognized income tax benefits recorded in its consolidated balance sheets.

Related-Party Transactions	Related-Party Transactions
	Henry Amalgamated
	In November 2012, the Company completed the purchase of its headquarters facilities (the “properties”), which were owned by Henry Amalgamated, LLC and Henry Amalgamated II, LLC, Indiana limited liability companies (together, “Henry Amalgamated”), for an aggregate purchase price of $6,250, excluding fees and other charges. In connection with its acquisition of the properties, the Company’s leases for its headquarters facilities were terminated.
	William S. Oesterle, the Company’s Chief Executive Officer and member of the Company’s board of directors, owned a 70% interest in Henry Amalgamated at the time of the transaction described above. As the transaction constitutes a related-party transaction at the direction of the board of directors (the “board”), the audit committee of the Company’s board reviewed and negotiated the Company’s acquisition of the property. With the audit committee’s recommendation and after a full board review, the board approved this transaction.
	Prior to the acquisition, the Company leased the properties purchased from Henry Amalgamated. In addition to the primary acquisition costs of $6,250, the Company paid $178 to Henry Amalgamated for other charges incurred to prepare the properties for use, of which $150 was capitalized with the purchase of the properties. Rent expense to Henry Amalgamated was $11 and $977 for 2013 and 2012, respectively. The Company did not make any payments to Henry Amalgamated during 2014, nor did the Company owe Henry Amalgamated any amounts as of December 31, 2014 or 2013.
	DocuSign
	During 2012, the Company entered into a contract with DocuSign Inc. ("DocuSign") for the provision of electronic signature technology and digital transaction management services to facilitate electronic exchanges of contracts and signed documents. The original contract expired in 2014, and a new contract was subsequently executed with a term extending to 2017. Keith J. Krach, who retired as the Chairman of the board in May 2014, currently serves as the Chief Executive Officer, President and Chairman of the board of directors of DocuSign. The Company's contract with DocuSign thereby represents a related-party transaction. Payments made by the Company to DocuSign for 2014, 2013 and 2012 were $134, $106 and $69, respectively. The Company did not owe DocuSign any amounts as of December 31, 2014 or 2013.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations
	Angie’s List, Inc. (collectively with its wholly owned subsidiaries, the "Company") operates a national local services consumer review service and marketplace where consumers can research, shop for and purchase local services for critical needs, such as home, health and automotive services, as well as rate and review the providers of these services. Ratings and reviews, which are available only to the Company’s members, assist members in identifying and hiring the best provider for their local service needs. Membership subscriptions are sold on a monthly, annual and multi-year basis. The consumer rating network “Angie’s List” is maintained and updated based on consumer feedback. The Company also sells advertising in its monthly publication, on its website and mobile application and through its call center to service providers that meet certain ratings criteria. In addition, the Company’s e-commerce marketplace offerings provide consumers with the opportunity to purchase services directly through the Company's marketplace from highly-rated service providers. The Company’s services are provided in markets located across the continental United States.
	Operating Segments
	Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one operating segment.
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
Estimates	Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes as well as the disclosure of contingent assets and liabilities and reported revenue and expenses. Actual results could differ from those estimates, but management does not believe such differences will materially affect Angie’s List, Inc.’s financial position or results of operations. The consolidated financial statements reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly present the results for the periods.
Reclassification of Prior Year Presentation	Reclassification of Prior Year Presentation
	Certain prior year amounts were reclassified for consistency with the current period presentation. These reclassifications did not materially impact the consolidated financial statements.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue
	The Company recognizes revenue when all of the following conditions are met: there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of fees is reasonably assured and the amount of fees to be paid by the customer is fixed or determinable.
	Membership Revenue
	Revenue from the sale of membership subscriptions is recognized ratably over the term of the associated subscription. Prior to 2014, the Company generally received a one-time, nonrefundable enrollment fee at the time a member joined. Enrollment fees are deferred and recognized on a straight-line basis over an estimated average membership life of 80 months for annual or multi-year members and 13 months for monthly members, which is based on historical membership experience. The Company reviews the estimated average membership lives on an annual basis, or more frequently if circumstances change. Changes in member behavior, performance, competition and economic conditions may cause attrition levels to change, which could impact the estimated average membership lives. The Company discontinued charging nonrefundable enrollment fees in 2014.
Service Provider Revenue	Service Provider Revenue
	Revenue from the sale of advertising in the Company’s Angie’s List Magazine publication is recognized in the month in which the publication is published and distributed. Revenue from the sale of website, mobile and call center advertising is recognized ratably over the time period the advertisements run. Revenue from e-commerce vouchers is recognized on a net basis when the voucher is delivered to the purchaser. While the Company is not the merchant of record with respect to its customers for these transactions, it does offer customers refunds in certain circumstances. Revenue from e-commerce transactions is recorded net of a reserve for estimated refunds. The Company’s e-commerce revenue was $27,133, $22,062 and $14,475 for 2014, 2013 and 2012, respectively.
Deferred Revenue	Deferred Revenue
	Deferred revenue includes the unamortized portion of revenue associated with membership and service provider fees for which the Company received payment in advance of services or advertising to be provided. Deferred revenue is recognized as revenue when the related services or advertising are actually provided.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company maintains its cash in bank deposit accounts and money market funds with contractual maturities of three months or less, which, at times, may exceed federally insured limits. The Company also classifies as cash and cash equivalents any investments in corporate bonds or certificates of deposit with original maturities of three months or less. To date, the Company has not incurred any losses in these accounts.
Short-Term Investments	Short-Term Investments
	Short-term investments consist of corporate bonds and certificates of deposit with maturities of more than 90 days but less than one year, all of which are designated as held-to-maturity investments and recorded at amortized cost, adjusted for amortization of premiums to maturity computed under the effective interest method, in the consolidated balance sheets. Amortization and interest income from held-to-maturity investments are included in interest expense, net, in the consolidated statements of operations. The Company’s objective with respect to these investments is to earn a higher rate of return on funds that are otherwise not anticipated to be required to meet liquidity needs in the near term while maintaining a low level of investment risk with the positive intent and ability to hold these investments to maturity. Short-term investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may be impaired. As of December 31, 2014 and 2013, the Company held $24,268 and $21,055, respectively, in short-term investments with no material unrealized gains or losses in these accounts in either year then ended.
Accounts Receivable	Accounts Receivable
	Accounts receivable is stated at the amount billed to service providers, less an estimated allowance for doubtful accounts. The Company performs ongoing credit evaluations and generally requires no collateral from service providers. Management reviews individual accounts as they become past due to determine collectability. The Company's allowance for doubtful accounts balance is adjusted periodically based on management’s consideration of past due accounts. Individual accounts are charged against the allowance when all reasonable collection efforts are exhausted.
	The changes in the Company's allowance for doubtful accounts balances during the years ended December 31, 2014, 2013 and 2012 were as follows:
		Year Ended December 31,
		2014			2013			2012
	Beginning balance	$	1,107		$	922		$	535
	Additions, net of recoveries	5,028			3,773			1,955
	Deductions	(4,484		)	(3,588		)	(1,568		)
	Ending balance	$	1,651		$	1,107		$	922
Property, Equipment and Software	Property, Equipment and Software
	Assets recorded as property, equipment and software are stated at cost and depreciated over their respective estimated useful lives. The Company also capitalizes certain costs related to website and software acquisition and development for internal use, including the associated interest costs incurred during development. Construction in progress is related to the construction or development of property, equipment and software that is not ready for its intended use and therefore not yet placed in service. The Company’s estimated useful lives for property, equipment and software range from 3 to 25 years. Depreciation is computed using the straight-line method. Repairs and routine maintenance are charged to expense as incurred.
	In accordance with authoritative guidance, the Company begins to capitalize website and software development costs for internal use when preliminary development efforts are successfully completed and technological feasibility is established. Costs incurred prior to the establishment of technological feasibility, together with costs incurred for related training and maintenance, are expensed as incurred and recorded in product and technology expense within the consolidated statements of operations.
	During 2014, the Company began capitalizing a portion of the interest on funds borrowed as part of its capitalized website and software development costs, primarily related to ongoing development around internal use software. For the year ended December 31, 2014, total interest costs incurred amounted to $2,613, of which $1,410 was capitalized as construction in progress for website and software development costs. No interest costs were capitalized for the years ended December 31, 2013 or 2012.
Goodwill	Goodwill
	Goodwill is not amortized and is instead reviewed for impairment, at a minimum, on an annual basis as of December 31, or more frequently should an event or circumstance occur that indicates the carrying amount of goodwill may be impaired. If goodwill is considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the goodwill exceeds its fair market value. To date, no impairment of goodwill has been identified or recognized.
Data Acquisition Costs	Data Acquisition Costs
	Data acquisition costs consist of external costs related to acquiring consumer reports on service providers. These reports are used by the Company to provide its members with feedback on service providers. Amortization is computed using the straight-line method over the period which the information is expected to benefit the Company’s members, which is estimated to be three years. The capitalized costs are included in intangible assets in the consolidated balance sheets, and the amortized expense is reflected within operations and support expense in the consolidated statements of operations.
Long-Lived Assets	Long-Lived Assets
	Long-lived assets, including property, equipment and software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by the related asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair market value of the assets. A one-time, long-lived asset impairment charge was recorded during the fourth quarter of the current year related to the Company's abandonment of certain capitalized website and software development assets and is discussed in more detail in Note 5, "Property, Equipment and Software," of this Form 10-K. To date, there have been no other adjustments to the respective carrying values of the Company's long-lived assets.
Deferred Financing Fees	Deferred Financing Fees
	As a result of its entry into a new financing agreement in September 2014, the Company incurred financing costs that were capitalized as a deferred financing fee asset and are being amortized into interest expense over the term of the credit facility. In connection with the extinguishment of the Company's previous loan and security agreement during the course of the aforementioned current year financing transaction, the Company expensed the remaining unamortized portion of the capitalized deferred financing fees associated with the previous loan and security agreement, and the related amount is included in the loss on debt extinguishment within the consolidated statements of operations.
Fees Paid to Lender	Fees Paid to Lender
	The Company incurred financing costs in the form of fees paid directly to the lender during the completion of its September 2014 long-term debt financing transaction. In accordance with the applicable authoritative guidance, these fees were recorded as a contra liability offsetting the gross term loan balance. The fees paid to lender contra liability is being amortized to interest expense on a straight-line basis over the term of the related debt. The Company's long-term debt balance is reported net of the remaining unamortized fees paid to the lender within the consolidated balance sheets.
Leases	Leases
	The Company leases office space pursuant to long-term noncancellable operating leases expiring through 2020. Rent expense is recognized on a straight-line basis over the expected lease term. Certain of the Company's leases contain provisions for tenant improvement allowances, which are recorded as a deferred rent liability and amortized over the term of the associated lease as an offset to rent expense each period. Leasehold improvements are capitalized to property, equipment and software and depreciated on a straight-line basis over the corresponding estimated useful lives.
Sales Commissions	Sales Commissions
	Commissions expense from the sale of service provider advertisements is recognized ratably over the term of the associated advertisement. The Company defers the recognition of commission expense until such time as the revenue related to the customer contract for which the commission was paid is recognized. Deferred commissions for each contract are amortized to expense in a manner consistent with how revenue is recognized for such contract, resulting in straight-line recognition of expense over the contractual term. Unamortized commission expense of $11,378 and $9,395 as of December 31, 2014 and 2013, respectively, is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
Marketing Expense	Marketing Expense
	Marketing expense consists of national television, radio and print advertising as well as online digital advertising. The Company expenses all advertising costs as incurred.
Stock-Based Compensation	Stock-Based Compensation
	The Company accounts for stock-based compensation using the fair value recognition provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 718, Stock Compensation. For its awards of stock options, the Company recognizes stock-based compensation expense in an amount equal to the fair market value on the grant date of the respective award. The Company recognizes this expense, net of estimated forfeitures, on a straight-line basis over the requisite service period. The fair value of awards granted is estimated at the date of grant using the Black-Scholes option-pricing model with the historical weighted-average assumptions outlined in Note 11, "Stock-Based Compensation," of this Form 10-K.
Loss On Debt Extinguishment	Loss on Debt Extinguishment
	The penalties, additional interest and other fees and expenses incurred in connection with the prepayment of the Company’s previous debt facility in September 2014, together with the amounts related to the write-off of the previous deferred financing fees and recognition of the remaining warrant interest expense under the prior debt facility, are included within the loss on debt extinguishment contained in the consolidated statement of operations for the year ended December 31, 2014.
Income Taxes	Income Taxes
	The Company is subject to corporate-level federal and state income taxes at prevailing corporate rates and accounts for income taxes and the related accounts using the asset and liability method in accordance with ASC 740, Income Taxes. Under this method, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between the book and tax basis of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted rates in effect for the years in which the differences are expected to reverse and recognizes the effect of a change in enacted rates in the period of enactment. After determining the total amount of deferred tax assets, the Company determines whether it is more likely than not that some portion of the deferred tax assets will not be realized. If the Company determines that a deferred tax asset is not likely to be realized, a valuation allowance will be established against that asset to record it at its expected realizable value. The Company establishes assets and liabilities for uncertain positions taken or expected to be taken in income tax returns using a more-likely-than-not recognition threshold. The Company includes in income tax expense any interest and penalties related to uncertain tax positions.
Sales and Use Tax	Sales and Use Tax
	Sales and use tax expenses are included within operations and support expense in the consolidated statements of operations. The Company does not separately collect sales and use taxes from its members.
Subsequent Events	Subsequent Events
	The Company evaluated subsequent events through the date these consolidated financial statements were issued.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In January 2015, the FASB issued Accounting Standards Update No. 2015-01: Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items ("ASU 2015-01"). The objective of this Update is to simplify the income statement presentation requirements in Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, by eliminating the concept of extraordinary items from U.S. GAAP. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. ASU 2015-01 will be effective for the Company in fiscal year 2016, and prospective application is permitted, with the lone required transition disclosure, if applicable, being the nature and the amount of an item included in income from continuing operations after adoption that adjusts an extraordinary item previously classified and presented before the date of adoption. The Company is currently assessing the future impact of this update to the consolidated financial statements.
	In August 2014, the FASB issued Accounting Standards Update No. 2014-15: Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). The update sets forth a requirement for management to evaluate whether there are conditions and events that raise substantial doubt about an entity's ability to continue as a going concern, a responsibility that did not previously exist in U.S. GAAP. The amendments included in this update require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 will be effective for the Company in fiscal year 2016. The Company is currently assessing the future impact of this update to the consolidated financial statements.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09: Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). The update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that "an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." The update also requires significantly expanded disclosures related to revenue recognition. ASU 2014-09 will be effective for the Company in fiscal year 2017. The Company is currently evaluating the future impact and method of adoption of this update with respect to the consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11: Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). An entity is required to present unrecognized tax benefits as a decrease in a net operating loss, similar tax loss or tax credit carryforward if certain criteria are met. The determination of whether a deferred tax asset is available is based on the unrecognized tax benefit and the deferred tax asset that exists at the reporting date and presumes disallowance of the tax position at the reporting date. The guidance eliminates the diversity in practice in the presentation of unrecognized tax benefits but does not alter the way in which entities assess deferred tax assets for realizability. ASU 2013-11 became effective and was adopted by the Company in fiscal year 2014 with no material impact to the consolidated financial statements.
