Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Organization and Description of Business Organization and Nature of Operations YuMe, Inc. (the "Company") was incorporated in Delaware on December 16, 2004. The Company, including its wholly-owned subsidiaries, is a leading independent provider of digital video brand advertising solutions. The Company's proprietary technologies serve the specific needs of brand advertisers and enable them to find and target large, brand-receptive audiences across a wide range of Internet-connected devices and digital media properties. The Company's software is used by global digital media properties to monetize professionally-produced content and applications. The Company facilitates digital video advertising by dynamically matching relevant audiences available through its digital media property partners with appropriate advertising campaigns from its advertising customers. The Company helps its advertising customers overcome the complexities of delivering digital video advertising campaigns in a highly fragmented environment where dispersed audiences use a growing variety of Internet-connected devices to access thousands of online and mobile websites and applications. The Company delivers video advertising impressions across personal computers, smartphones, tablets, set-top boxes, game consoles, Internet-connected TVs and other devices. The Company's video ads run when users choose to view video content on their devices. On each video advertising impression, the Company collects dozens of data elements that it uses for its advanced audience modeling algorithms that continuously improve brand-targeting effectiveness. Basis of Presentation The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2016. The condensed consolidated balance sheet as of December 31, 2015, included herein was derived from the Company’s audited consolidated financial statements as of that date but does not include all disclosures required by GAAP, including notes to the financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the interim periods stated. Basis of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain Significant Risks and Uncertainties The Company operates in a dynamic industry and, accordingly, its financial results can be affected by a variety of factors. For example, the Company believes that changes in the following areas, among others, could have a significant negative effects on its future financial position, results of operations, or cash flows: rates of revenue growth; traffic to and pricing with the Company's network of digital media property owners; scaling and adaptation of existing technology and network infrastructure; adoption of the Company’s product and solution offerings; management of the Company's strategic direction; development of new markets and opportunities for international expansion; protection of the Company's brand, reputation and intellectual property; competition in the Company's markets; success in recruiting and retaining qualified employees and key personnel; emergence of intellectual property infringement and other claims; and government regulation affecting the Company's business.

Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Use of Estimates The preparation of the Company's consolidated financial statements in conformity with GAAP requires management 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 financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management's estimates. Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date In January 2015, the FASB issued ASU 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items In January 2016, the FASB issued ASU 2016-01, Financial Instruments--Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842) In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) The Company is currently evaluating the impact of adopting this standard. Concentrations and Other Risks Financial instruments that subject the Company to a concentration of credit risk consist of cash and cash equivalents, marketable securities and accounts receivable. Cash and cash equivalents are deposited with one domestic and five foreign highly rated financial institutions and cash equivalents are invested in highly rated money market funds. Periodically, such balances may be in excess of federally insured limits. Marketable securities consist of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Credit risk with respect to accounts receivable is dispersed due to the large number of advertising customers. Collateral is not required for accounts receivable. The Company performs ongoing credit evaluations of customers’ financial condition and periodically evaluates its outstanding accounts receivable and establishes an allowance for doubtful accounts receivable based on the Company’s historical experience, the current aging and circumstances of accounts receivable and general industry and economic conditions. Accounts receivable are written off by the Company when it has been determined that all available collection avenues have been exhausted. In the three months ended March 31, 2016 and 2015, bad debt write-offs totaled $0.1 million and $46,000, respectively. If circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates. No customers accounted for 10% or more of the Company’s accounts receivable as of March 31, 2016 or December 31, 2015. The following table presents the changes in the allowance for doubtful accounts (in thousands): Three Months Ended March 31, 2016 2015 Allowance for doubtful accounts receivable: Balance – beginning of period $ 1,961 $ 1,471 Allowance for doubtful accounts receivable 33 240 Doubtful accounts receivable write-offs (134 ) (46 ) Balance – end of period $ 1,860 $ 1,665

Notes to Financial Statements
Cash, Cash Equivalents, and Marketable Securities [Text Block]	3. Cash, Cash Equivalents, Marketable Securities and Derivative Instruments The Company’s cash equivalents consist of highly liquid fixed-income investments with original maturities of three months or less at the time of purchase . Short- and long-term marketable securities are comprised of highly liquid available-for-sale financial instruments (primarily corporate bonds, commercial paper and certificates of deposit) with final maturities of at least three months but no more than 24 months from the date of purchase . None of the Company’s marketable securities were in a continuous loss position for over twelve months as of March 31, 2016. Beginning in the second quarter of 2015, the Company entered into non-designated derivative instruments, specifically foreign currency forward contracts, to partially offset the foreign currency exchange gains and losses generated by the re-measurement of certain assets and liabilities denominated in non-functional currencies. The Company’s foreign currency forward contracts have terms of no more than 12 months, are classified as Level 2 and are valued using alternative pricing sources, such as spot currency rates, that are observable for the entire term of the asset or liability. These derivatives that are not designated as hedging instruments are adjusted to fair value through earnings in other income (expense), net in the consolidated statement of operations. The cost, gross unrealized gains and losses and fair value of the Company’s cash and cash equivalents, marketable securities and foreign currency forward contracts consisted of the following as of March 31, 2016 and December 31, 2015 (in thousands): Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value March 31, 2016: Cash $ 23,103 $ — $ — $ 23,103 Cash equivalents: Money market funds 10,167 — — 10,167 Total cash and cash equivalents 33,270 — — 33,270 Marketable securities: Corporate bonds 23,130 11 (8 ) 23,133 Government agency bonds 7,819 4 — 7,823 Commercial paper 1,599 — — 1,599 Total marketable securities 32,548 15 (8 ) 32,555 Total cash, cash equivalents and marketable securities $ 65,818 $ 15 $ (8 ) $ 65,825 Forward currency forward contracts $ — $ 107 $ — $ 107 Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2015: Cash $ 7,638 $ — $ — $ 7,638 Cash equivalents: Money market funds 10,221 — — 10,221 Total cash and cash equivalents 17,859 — — 17,859 Marketable securities: Corporate bonds 31,372 — (78 ) 31,294 Government agency bonds 6,544 — (8 ) 6,536 Commercial paper 4,494 — — 4,494 Total marketable securities 42,410 — (86 ) 42,324 Total cash, cash equivalents and marketable securities $ 60,269 $ — $ (86 ) $ 60,183 Forward currency forward contracts $ — $ (10 ) $ — $ (10 ) Unrealized gains and losses, net of taxes, are included in “Accumulated other comprehensive loss,” which is reflected as a separate component of stockholders’ equity on the condensed consolidated balance sheets. Restricted Cash The Company’s lease agreement for its New York office requires a security deposit in the amount of $0.4 million to be maintained in the form of an unconditional, irrevocable letter of credit issued to the benefit of the landlord. The letter of credit is subject to renewal annually until the lease expires in September 2027. On July 1, 2020, the required security deposit will decrease to $0.3 million. The lease agreement for the Company's previous New York office required a security deposit in the amount of $0.3 million to be maintained in the form of an unconditional, irrevocable letter of credit issued to the benefit of the landlord. The letter of credit will expire in the second quarter of 2016. As of March 31, 2016 and December 31, 2015, the Company had letters of credit totaling $0.7 million and $0.3 million, respectively, included in restricted cash (current and non-current) in the consolidated balance sheets.

Note 4 - Fair Value of Financial Instruments	Mar. 31, 2016
Notes to Financial Statements
Fair Value Disclosures [Text Block]	4. Fair Value of Financial Instruments The accounting guidance for fair value measurements prioritizes the inputs used in measuring fair value in the following hierarchy: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3 – Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The carrying amounts of accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. Marketable securities with final maturities of at least three months but no more than 12 months from the date of purchase are classified as short-term and marketable securities with final maturities of more than one year but less than two years from the date of purchase are classified as long-term. The Company’s marketable securities are classified as available-for-sale and consist of high quality, investment grade securities from diverse issuers with predetermined minimum credit ratings. The Company values these securities based on pricing information from pricing vendors who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. However, the Company classifies all of its marketable securities as having Level 2 inputs. The valuation techniques used to measure the fair value of the Company’s marketable securities having Level 2 inputs were derived from market prices that are corroborated by observable market data and quoted market prices for similar instruments. The following tables present information about the Company’s money market funds, marketable securities and foreign currency forward contracts, measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands): Fair Value Measurements at March 31, 2016 Level 1 Level 2 Level 3 Total Money market funds (1) $ 10,167 $ — $ — $ 10,167 Marketable securities: Corporate bonds $ — $ 23,133 $ — $ 23,133 Government and agency bonds 7,823 7,823 Commercial paper — 1,599 — 1,599 Total marketable securities $ — $ 32,555 $ — $ 32,555 Foreign currency forward contracts (2) $ — $ 107 $ — $ 107 (1) Included in “Cash and cash equivalents” in the accompanying condensed consolidated balance sheet as of March 31, 2016.

Notes to Financial Statements
Derivative Instruments and Hedging Activities Disclosure [Text Block]	5. Foreign Currency Transaction Risk Foreign Currency Forward Contracts The Company transacts business in various foreign currencies and in the second quarter of 2015 established a program that utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. Under this program, to the Company enters into foreign currency forward contracts so that increases or decreases in foreign currency exposures are offset at least in part by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with the Company’s foreign currency transactions. The Company may suspend this program from time to time. Foreign currency exposures typically arise from British pound and euro denominated transactions that the Company expects to cash settle in the near term, which are charged against earnings in the period incurred. The Company’s foreign currency forward contracts are short-term in duration. The Company does not use foreign currency forward contracts for trading purposes nor does it designate forward contracts as hedging instruments pursuant to ASC 815. Accordingly, the Company records the fair values of these contracts as of the end of its reporting period to its condensed consolidated balance sheets with changes in fair values recorded to its condensed consolidated statement of operations. Given the short duration of the forward contracts, the amount recorded is not significant. The balance sheet classification for the fair values of these forward contracts is prepaid expenses and other current assets for a net unrealized gain position, and accrued liabilities for a net unrealized loss position. The statement of operations classification for changes in fair value of these forward contracts is other expense, net for both realized and unrealized gains and losses. The Company expects to continue to realize gains or losses with respect to its foreign currency exposures, net of gains or losses from its foreign currency forward contracts. The Company’s ultimate realized gain or loss with respect to foreign currency exposures will generally depend on the size and type of cross-currency transactions that it enters into, the currency exchange rates associated with these exposures and changes in those rates, the net realized gain or loss on its foreign currency forward contracts and other factors. As of March 31, 2016, the notional amount and the aggregate fair value of the forward contracts the Company held to purchase U.S. dollars in exchange for British pounds and euros was $6.6 million. Net foreign exchange transaction gains/(losses) relating to the Company’s British pound sterling and euro forward contracts are included in other income (expense), net in the Company’s consolidated statements of operations. Net foreign exchange transaction losses were $0.2 million for the three months ended March 31, 2016 and were partially offset by $0.1 million of realized gains on forward contracts. Net foreign exchange transaction losses were $0.4 million for the three months ended March 31, 2015 and were not offset as the Company had not yet established its program that utilizes foreign currency forward contracts to reduce net foreign exchange transaction gains and losses.

Purchase Commitments During the normal course of business, to secure adequate ad inventory and impressions for its sales arrangements, the Company periodically enters into agreements with digital media property owners that require purchase of a minimum number of impressions on a monthly or quarterly basis. Purchase commitments as of March 31, 2016 expire on various dates through December 2016. Legal Proceedings From time to time the Company may be a party to various litigation matters incidental to the conduct of its business. There is no pending or threatened legal proceeding to which the Company is currently a party that, in management’s opinion, is likely to have a material adverse effect on the Company’s condensed consolidated financial position, results of operations, or cash flows. Indemnification Agreements In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. While matters may arise as a result of claims under the indemnification agreements disclosed above, the Company, at this time, is not aware of claims under indemnification arrangements that could have a material adverse effect to the Company’s consolidated financial position, results of operations, or cash flows.

Stockholders' Equity Note Disclosure [Text Block]	9. Stockholders’ Equity Preferred Stock In association with the Company’s initial public offering in 2013 (“IPO”), the board of directors authorized the Company to issue up to 20,000,000 shares of preferred stock, par value $0.001 per share. As of March 31, 2016 and December 31, 2015 no shares of preferred stock were outstanding. Common Stock At March 31, 2016 and December 31, 2015 there were 34,788,813 and 34,455,220 shares of common stock issued and outstanding, respectively. The following table summarizes common stock activity during the three months ended March 31, 2016: Number of Shares Outstanding at December 31, 2015 34,455,220 Option exercises 6,727 RSUs released, net of shares withheld for taxes 222,905 Common stock issued in connection with employee stock purchase plan 257,944 Repurchases of common stock (153,983 ) Outstanding at March 31, 2016 34,788,813 Treasury Stock In addition to the 153,983 shares repurchased in the three months ended March 31, 2016, the Company has 66,666 shares of treasury stock related to the acquisition of Crowd Science, for a total of 220,649 shares of treasury stock. Treasury stock is carried at cost and could be re-issued if the Company determined to do so. Equity Incentive Plans The Company’s 2004 Stock Plan (the “2004 Plan”) authorized the Company to grant restricted stock awards or stock options to employees, directors and consultants at prices not less than the fair market value at date of grant for incentive stock options and not less than 85% of fair market value for non-statutory options. Option vesting schedules were determined by the board of directors at the time of issuance and they generally vest at 25% on the first anniversary of the grant (or the employment or service commencement date) and monthly over the next 36 months. Options generally expire ten years from the date of grant unless the optionee is a 10% stockholder, in which case the term will be five years from the date of grant. Unvested options exercised are subject to the Company’s repurchase right. Upon the effective date of the registration statement related to the Company’s IPO, the 2004 Plan was amended to cease the grant of any additional awards thereunder, although the Company will continue to issue common stock upon the exercise of stock options previously granted under the 2004 Plan . In July 2013, the Company adopted a 2013 Equity Incentive Plan (the “2013 Plan”) which became effective on August 6, 2013. The 2013 Plan serves as the successor equity compensation plan to the 2004 Plan. The 2013 Plan will terminate on July 23, 2023. The 2013 Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation rights, performance stock awards, restricted stock units (“RSUs”) and stock bonus awards to employees, directors and consultants. Stock options granted must be at prices not less than 100% of the fair market value at date of grant. Option vesting schedules are determined by the Company at the time of issuance and they generally vest at 25% on the first anniversary of the grant (or the employment or service commencement date) and monthly over the next 36 months. Options generally expire ten years from the date of grant unless the optionee is a 10% stockholder, in which case the term will be five years from the date of grant. Unvested options exercised are subject to the Company’s repurchase right. The Company initially reserved 2,000,000 shares of its common stock for issuance under the 2013 Plan, and shares reserved for issuance increase January 1 of each year by the lesser of (i) 5% of the number of shares issued and outstanding on December 31 immediately prior to the date of increase or (ii) such number of shares as may be determined by the board of directors. Prior to the IPO, the fair value of the common stock underlying the Company’s stock options was determined by the Company’s board of directors, which intended all options granted to be exercisable at a price per share not less than the per-share fair value of the Company’s common stock underlying those options on the date of grant. The valuations of the Company’s common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions the Company used in the valuation model are based on future expectations combined with management judgment. In the absence of a public trading market, the Company’s board of directors, with input from management, exercised significant judgment and considered numerous objective and subjective factors to determine the fair value of the Company’s common stock as of the date of each option grant. Subsequent to the IPO, the fair value of the common stock underlying the Company’s stock options is the closing price of the Company’s stock as of the grant date. The following table summarizes option activity: Number of Shares (in thousands) Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (years) Aggregate Intrinsic Value ( 1 ) (in thousands) Balance at December 31, 2015 4,360 $ 5.04 6.30 $ 1,480 Granted 306 $ 3.61 Exercised (7 ) $ 1.08 Canceled and forfeited (61 ) $ 5.26 Balance at March 31, 2016 4,598 $ 4.95 5.98 $ 1,624 Vested as of March 31, 2016 and expected to vest thereafter (2) 4,414 $ 4.94 5.87 $ 1,609 Vested and exercisable as of March 31, 2016 3,247 $ 4.64 5.06 $ 1,556 (1) The aggregate intrinsic value represents the difference between the Company’s estimated fair value of its common stock and the exercise price of outstanding in-the-money options as of those dates. (2) Options expected to vest reflect an estimated forfeiture rate. The weighted average grant date fair value of options granted was $1.93 and $2.99 in the three months ended March 31, 2016 and 2015, respectively. The aggregate intrinsic value represents the difference between the market value of the Company’s common stock and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was approximately $19,000 and $0.3 million for the three months ended March 31, 2016 and 2015, respectively. The following table summarizes restricted stock unit activity: Number of Shares (in thousands) Weighted Average Fair Value at Grant Weighted Average Remaining Contractual Life (years) Aggregate Intrinsic Value (1) (in thousands) Balance at December 31, 2015 1,619 $ 5.39 0.99 $ 5,681 Granted 1,674 $ 3.85 Released (282 ) $ 5.62 Canceled and forfeited (26 ) $ 5.67 Balance at March 31, 2016 2,985 $ 4.50 1.39 $ 11,164 (1) The intrinsic value of RSUs is based on the Company’s closing stock price as reported by the New York Stock Exchange on March 31, 2016 and December 31, 2015. The total grant date fair value of restricted stock units vested during the three-month periods ended March 31, 2016 and 2015 was $1.0 million and $34,000, respectively. All of the Company’s RSUs that were released during the three months ended March 31, 2016 and 2015 were net share settled. As such, upon each release date, RSUs were withheld to cover the required withholding tax, which is based on the value of the RSU on the release date as determined by the closing price of the Company’s common stock on the trading day of the settlement date. The remaining amounts are delivered to the recipient as shares of Company common stock. Modification of Employee Stock Options On January 2, 2015, the Company modified options to purchase 0.7 million shares of common stock previously granted to non-executive employees with exercise prices over $7.00 per share. The exercise price of the modified options was reduced to $5.14 per share, the closing price of the Company’s common stock on the New York Stock Exchange on January 2, 2015. No other terms of these options were modified. The Company expects to recognize an additional $0.4 million of stock-based compensation expense over the remaining vesting terms of the options as a result of the modification. As of March 31, 2016, $0.1 million of the additional stock-based compensation expense remains to be expensed. Employee Stock Purchase Plan In July 2013, the Company adopted a 2013 Employee Stock Purchase Plan (the “2013 Purchase Plan”) that became effective on August 6, 2013. The 2013 Purchase Plan is designed to enable eligible employees to periodically purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. At the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period . Purchases are accomplished through participation in discrete offering periods. The 2013 Purchase Plan is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. The Company initially reserved 500,000 shares of its common stock for issuance under the 2013 Purchase Plan and shares reserved for issuance increase January 1 of each year by the lesser of (i) a number of shares equal to 1% of the total number of outstanding shares of common stock on December 31 immediately prior to the date of increase or (ii) such number of shares as may be determined by the board of directors. The expected term of ESPP shares is the average of the remaining purchase periods under each offering period. The assumptions used to value employee stock purchase rights were as follows: Three Months Ended March 31 , 2016 201 5 Expected term (years) 0.50 0.50 Volatility 56 % 56 % Risk-free interest rate 0.45 % 0.07 % Dividend yield — — Stock Repurchase Program On February 18, 2016, the Company announced its board of directors authorized a $10 million share repurchase program. The authorization has no set expiration date, but, subject to market conditions and other factors, is intended to be completed over the next twelve months. Purchases under this repurchase program are made in the open market and complied with Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The cost of the repurchased shares is funded from available working capital. For accounting purposes, common stock repurchased under the Company’s stock repurchase program is recorded based upon the repurchase date of the applicable trade. Such repurchased shares are held in treasury and are presented using the cost method. Stock repurchase activity under the Company’s stock repurchase program during the three months ended March 31, 2016 is summarized as follows (in thousands, except share and per share amounts): Total Number of Shares Repurchased Average Price Paid per Share (1) Amount of Repurchase Cumulative balance at December 31, 2015 — $ — $ — Repurchases of common stock 153,983 $ 3.67 565 Cumulative balance at March 31, 2016 153,983 $ 3.67 $ 565 (1) Average price paid per share includes commission. In addition to the 153,983 shares repurchased under the repurchase program, the Company holds 66,666 shares of treasury stock related to the acquisition of Crowd Science, for a total of 220,649 shares of treasury stock. Treasury stock could be re-issued if the Company determined to do so. Shares Reserved for Future Issuance At March 31, 2016 and December 31, 2015, the Company has reserved the following shares of common stock for future issuance: March 31, 201 6 December 31, 201 5 Common stock reserved: Common stock options 4,597,905 4,360,015 Restricted stock units 2,985,055 1,618,543 Shares available for future issuance under the 2013 Plan 3,570,464 3,680,862 Employee stock purchase plan 525,918 437,934 11,679,342 10,097,354 Stock-Based Compensation The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), volatility of the Company’s common stock, a risk-free interest rate, expected dividends, and the estimated forfeitures of unvested stock options. To the extent actual results differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. The Company uses the simplified calculation of expected life, and volatility is based on an average of the historical volatilities of the common stock of a group of entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. Expected forfeitures are based on the Company’s historical experience. The Company currently has no history or expectation of paying cash dividends on common stock. The fair value of options granted to employees is determined using the Black-Scholes option valuation model with the following assumptions: Three Months Ended March 31 , 2016 201 5 Expected term (years) 6.00 6.00 Volatility 56.0 % 56.0 % Risk-free interest rate 1.895 % 1.540 % Dividend yield — — Weighted-average fair value $ 1.93 $ 1.11 The following table summarizes the effects of stock-based compensation related to vesting stock-based awards included in the consolidated statements of operations (in thousands): Three Months Ended March 31 , 2016 2015 Cost of revenue (1) $ 45 $ 112 Sales and marketing 719 900 Research and development (2) 301 204 General and administrative 1,107 878 Total stock-based compensation $ 2,172 $ 2,094 (1) Excludes $6,000 for the three months ended March 31, 2015 that was capitalized as part of internal-use software development costs. (2) Excludes $146,000 and $126,000 of stock-based compensation expense that was capitalized as part of internal-use software development costs for the three months ended March 31, 2016 and 2015, respectively. No income tax benefit has been recognized relating to stock-based compensation expense and no tax benefits have been realized from exercised stock options during the three months ended March 31, 2016 and 2015. As of March 31, 2016, there was $13.6 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested stock-based awards, which will be recognized over a weighted average period of 2.24 years. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. 401(k) Plan The Company’s 401(k) Plan (the “401(k) Plan”) is a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the 401(k) Plan, participating U.S. employees may defer a portion of their pre-tax earnings, up to the IRS annual contribution limit of $18,000 for calendar years 2016 and 2015. The Company began matching employee contributions in April 2014. The Company will match 50% of each participating employee’s contributions up to a maximum of 6% of each employee’s eligible earnings with an annual maximum match of $2,500 per employee per year.

Income Tax Disclosure [Text Block]	10. Income Taxes The Company’s provision for income taxes consists of federal and state income taxes in the U.S. and income taxes in certain foreign jurisdictions, deferred income taxes reflecting the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and the realization of net operating loss carryforwards. For both the three months ended March 31, 2016 and 2015, income tax expense was primarily related to state taxes and taxes due in foreign jurisdictions. The following table summarizes our income tax expense and our effective tax rates for the three months ended March 31, 2016 and 2015 (in thousands, except effective tax rate): Three Months Ended March 31 , 2016 2015 Loss before income taxes $ (3,543 ) $ (5,910 ) Income tax expense $ 55 $ 86 Effective tax rate (1.6 )% (1.5 )% A valuation allowance is provided when it is more likely than not that the Company’s deferred tax assets will not be realized. The Company’s practice is to establish a full valuation allowance to offset domestic net deferred tax assets. As of March 31, 2016 and December 31, 2015, a full valuation allowance on domestic deferred tax assets were placed due to the uncertainty of realizing future tax benefits from the Company’s net operating loss carryforwards and other deferred tax assets. The federal and state valuation allowance increased by approximately $2.0 million during the three months ended March 31, 2016. As of March 31, 2016, the Company has U.S. federal net operating loss carryforwards of approximately $27.3 million, expiring beginning in 2026. As of March 31, 2016, the Company has U.S. state and local net operating loss carryforwards of approximately $21.7 million, expiring beginning in 2016.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2016. The condensed consolidated balance sheet as of December 31, 2015, included herein was derived from the Company’s audited consolidated financial statements as of that date but does not include all disclosures required by GAAP, including notes to the financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the interim periods stated.
Consolidation, Policy [Policy Text Block]	Basis of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Significant Risks and Uncertainties Policy [Policy Text Block]	Certain Significant Risks and Uncertainties The Company operates in a dynamic industry and, accordingly, its financial results can be affected by a variety of factors. For example, the Company believes that changes in the following areas, among others, could have a significant negative effects on its future financial position, results of operations, or cash flows: rates of revenue growth; traffic to and pricing with the Company's network of digital media property owners; scaling and adaptation of existing technology and network infrastructure; adoption of the Company’s product and solution offerings; management of the Company's strategic direction; development of new markets and opportunities for international expansion; protection of the Company's brand, reputation and intellectual property; competition in the Company's markets; success in recruiting and retaining qualified employees and key personnel; emergence of intellectual property infringement and other claims; and government regulation affecting the Company's business.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the Company's consolidated financial statements in conformity with GAAP requires management 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 financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management's estimates.

Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations and Other Risks Financial instruments that subject the Company to a concentration of credit risk consist of cash and cash equivalents, marketable securities and accounts receivable. Cash and cash equivalents are deposited with one domestic and five foreign highly rated financial institutions and cash equivalents are invested in highly rated money market funds. Periodically, such balances may be in excess of federally insured limits. Marketable securities consist of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Credit risk with respect to accounts receivable is dispersed due to the large number of advertising customers. Collateral is not required for accounts receivable. The Company performs ongoing credit evaluations of customers’ financial condition and periodically evaluates its outstanding accounts receivable and establishes an allowance for doubtful accounts receivable based on the Company’s historical experience, the current aging and circumstances of accounts receivable and general industry and economic conditions. Accounts receivable are written off by the Company when it has been determined that all available collection avenues have been exhausted. In the three months ended March 31, 2016 and 2015, bad debt write-offs totaled $0.1 million and $46,000, respectively. If circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates. No customers accounted for 10% or more of the Company’s accounts receivable as of March 31, 2016 or December 31, 2015. The following table presents the changes in the allowance for doubtful accounts (in thousands): Three Months Ended March 31, 2016 2015 Allowance for doubtful accounts receivable: Balance – beginning of period $ 1,961 $ 1,471 Allowance for doubtful accounts receivable 33 240 Doubtful accounts receivable write-offs (134 ) (46 ) Balance – end of period $ 1,860 $ 1,665
