Disclosure Text Block [Abstract]
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 offers audience targeting capabilities to its advertisers by dynamically matching relevant audiences available through its digital media property partners with appropriate advertising campaigns. 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 the 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 pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 with the SEC on March 10, 2015. The condensed consolidated balance sheet as of December 31, 2014, included herein was derived from the 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, can be affected by a variety of factors. For example, the Company believes that changes in any of the following areas could have a significant negative effect 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 solutions; management of the Company's growth; new markets and international expansion; protection of the Company's brand, reputation and intellectual property; competition in the Company's markets; recruiting and retaining qualified employees and key personnel; intellectual property infringement and other claims; and changes in government regulation affecting the Company's business, among other things.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Use of Estimates The preparation of the Company's condensed 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), which amends the existing accounting standards for revenue recognition. Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. The original effective date for ASU 2014-09 would have required the Company to adopt beginning in its first quarter of 2017. In July 2015, the FASB voted to amend ASU 2014-09 by approving a one-year deferral of the effective date as well as providing the option to early adopt the standard on the original effective date. Accordingly, the Company may adopt the standard in either its first quarter of 2017 or its first quarter of 2018. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently evaluating the timing of its adoption and the impact of adopting the new revenue standard on its consolidated financial statements. 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 primarily consist of highly liquid corporate bonds, government agency bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Except for a single advertising agency customer noted below, 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 and six months ended June 2015, uncollectible account write-offs totaled $42,000 and $0.1 million, respectively. No uncollectible amounts were written off in the three and six months ended June 30, 2014. Prior to 2014, write-offs for uncollectible accounts were not significant. However, if circumstances change, higher than expected uncollectible accounts may result in future write-offs that are greater than the Company’s estimates. A single advertising agency accounted for approximately 11% of the Company’s accounts receivable as of June 30, 2015. No other customers accounted for 10% or more of the Company’s accounts receivable as of June 30, 2015 and December 31, 2014. The following table presents the changes in the allowance for doubtful accounts (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Allowance for doubtful accounts receivable: Balance – beginning of period $ 1,665 $ 1,266 $ 1,471 $ 1,056 Allowance for doubtful accounts receivable (17 ) 39 223 249 Doubtful accounts receivable write-offs (42 ) — (88 ) — Balance – end of period $ 1,606 $ 1,305 $ 1,606 $ 1,305

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	3. 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 it receives from security 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. 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 condensed consolidated statement of operations . 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 June 30, 2015 and December 31, 2014 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 June 30, 2015 Level 1 Level 2 Level 3 Total Money market funds (1) $ 10,896 $ — $ — $ 10,896 Marketable securities: Corporate bonds $ — $ 32,587 $ — $ 32,587 Government agency bonds 7,802 7,802 Commercial paper — 1,200 — 1,200 Total marketable securities $ — $ 41,589 $ — $ 41,589 Foreign currency forward contracts, net (2) $ — $ 118 $ — $ 118 (1) Included in “Cash and cash equivalents” in the accompanying condensed consolidated balance sheet as of June 30, 2015.

Cash, Cash Equivalents, and Marketable Securities [Text Block]	4. 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, government agency 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 . Foreign currency forward contracts consist of contracts to sell British pound sterling and euro as future specified prices and have terms of no more than 12 months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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 income (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 June 30, 2015, the notional amount of the forward contracts the Company held to purchase U.S. dollars in exchange for British pounds and euros was $4.8 million and the aggregate fair value was $4.9 million. Net foreign exchange transaction gains included in other income (expense), net in the Company’s condensed consolidated statements of operations was $0.3 million for the three months ended June 30, 2015, which included $0.4 million of net gains, partially offset by a $0.1 million loss relating to the Company’s British pound sterling and euro forward contracts. For the six months ended June 30, 2015, net foreign transaction exchange gains and losses in the Company’s condensed consolidated statements of operations were not material.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	9. Stockholders’ Equity Preferred Stock Immediately following the closing of the Company’s initial public offering (“IPO”), to the Company’s certificate of incorporation was amended to, among other things, authorize the Company to issue up to 20,000,000 shares of preferred stock, par value $0.001 per share. As of June 30, 2015 and December 31, 2014, no shares of preferred stock were outstanding. Common Stock Immediately following the closing of the Company’s IPO, the Company’s certificate of incorporation was amended to, among other things, authorize the Company to issue up to 200,000,000 shares of common stock. As of June 30, 2015 and December 31, 2014, there were 33,774,422 and 33,066,327 shares of common stock issued and outstanding, respectively. The following table summarizes common stock activity: Number of Shares Outstanding at December 31, 2014 33,066,327 Common stock issued in association with option and warrant exercises 199,075 Common stock issued in association with restricted stock units vesting 338,652 Common stock issued in association with the employee stock purchase plan 170,368 Outstanding at June 30, 2015 33,774,422 Treasury Stock As of June 30, 2015 and December 31, 2014, the Company held 66,666 shares of treasury stock related to the acquisition of Crowd Science, Inc. Treasury stock is carried at cost and could be re-issued if the Company determined to do so. Shares Reserved for Future Issuance As of June 30, 2015 and December 31, 2014, the Company has reserved the following shares of common stock for future issuance: As of June 30, 2015 As of December 31, 2014 Common stock reserved: Common stock options 4,922,280 5,058,641 Restricted stock units 2,031,762 1,082,939 Warrants to purchase common stock — 24,838 Shares available for future issuance under the 2013 Equity Incentive Plan 1,219,409 984,455 Employee stock purchase plan 664,309 504,014 8,837,760 7,654,887 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 . The Company’s 2013 Equity Incentive Plan (the “2013 Plan”) 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 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 lesser number of shares as may be determined by the board of directors. On January 1, 2015, shares reserved for issuance under the 2013 Plan increased by 1,653,316. 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 award activity: Number of Shares (in thousands) Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life ( y ears) Aggregate Intrinsic Value (in thousands) Balance at December 31, 2014 5,059 $ 5.54 5.78 $ 3,461 Granted (1) 1,005 $ 5.24 Exercised (187 ) $ 2.81 Cancelled and forfeited (2) (955 ) $ 8.10 Balance at June 30, 2015 4,922 $ 5.09 6.69 $ 4,221 Vested as of June 30, 2015 and expected to vest thereafter (3) 4,671 $ 5.02 6.60 $ 4,187 Vested and exercisable as of June 30, 2015 3,141 $ 4.40 5.78 $ 3,939 (1) Options granted include 0.7 million re-issued options in connection with a modification. See “ Modification of Employee Stock Options” (2) Options cancelled and forfeited include 0.7 million options that were cancelled in connection with a modification. See “ Modification of Employee Stock Options” (3) Options expected to vest reflect an estimated forfeiture rate. The weighted average grant date fair value of options granted was $2.70 and $2.91 in the three and six months ended June 30, 2015, respectively, and was $3.73 and $3.82 in the three and six months ended June 30, 2014, 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 $0.2 million and $0.5 million for the three and six months ended June 30, 2015, respectively, and was $0.4 million and $1.6 million for the three and six months ended June 30, 2014, 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, 2014 1,083 $ 5.92 1.39 $ 5,458 Granted 1,459 $ 5.61 Released (340 ) $ 6.06 Cancelled and forfeited (170 ) $ 6.07 Balance at June 30, 2015 2,032 $ 5.66 1.12 $ 11,012 (1) The intrinsic value of RSUs is based on the Company’s closing stock price as reported by the New York Stock Exchange on June 30, 2015. 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, which represents 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. Employee Stock Purchase Plan The Company’s 2013 Employee Stock Purchase Plan (the “2013 Purchase Plan”) became effective on August 6, 2013 and 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 originally 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. A total of 170,368 shares were purchased by employees under the Company’s ESPP for the six months ended June 30, 2015. The expected term of the 2013 Purchase Plan 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 June 30, Six Months Ended June 30, 201 5 2014 2015 201 4 Expected term (years) 0.50 0.50 0.50 0.50 Volatility 56% 80% 56% - 80% 80% Risk-free interest rate 0.07% 0.08% 0.05% - 0.07% 0.08% Dividend yield — — — — 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 option grants is determined using the Black-Scholes option valuation model with the following assumptions: Three Months Ended June 30, Six Months Ended June 30, 201 5 2014 2015 201 4 Expected term (years) 6.00 6.00 6.00 6.00 Volatility 56% 80% 56% 80% Risk-free interest rate 1.79% 2.02% 1.54% - 1.79% 1.89% - 2.02% Dividend yield — — — — The following table summarizes the effects of stock-based compensation related to vesting stock-based awards included in the Company’s accompanying condensed consolidated statements of operations (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Cost of revenue (1) $ 69 $ 84 $ 181 $ 147 Sales and marketing 1,026 664 1,926 1,228 Research and development (2) 316 146 520 193 General and administrative 1,105 429 1,983 916 Total employee stock-based compensation $ 2,516 $ 1,323 $ 4,610 $ 2,484 (1) Excludes $6,000 for the six months ended June 30, 2015 that was capitalized as part of internal-use software development costs. (2) Excludes $126,000, and $252,000 for the three and six months ended June 30, 2015, respectively, and $72,000 and $176,000 for the three and six months ended June 30, 2014, respectively, that was capitalized as part of internal-use software development costs. 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 $17,500 for calendar years 2014 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.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	6 Months Ended

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 the 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 pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 with the SEC on March 10, 2015. The condensed consolidated balance sheet as of December 31, 2014, included herein was derived from the 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, can be affected by a variety of factors. For example, the Company believes that changes in any of the following areas could have a significant negative effect 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 solutions; management of the Company's growth; new markets and international expansion; protection of the Company's brand, reputation and intellectual property; competition in the Company's markets; recruiting and retaining qualified employees and key personnel; intellectual property infringement and other claims; and changes in government regulation affecting the Company's business, among other things.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the Company's condensed 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.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. The original effective date for ASU 2014-09 would have required the Company to adopt beginning in its first quarter of 2017. In July 2015, the FASB voted to amend ASU 2014-09 by approving a one-year deferral of the effective date as well as providing the option to early adopt the standard on the original effective date. Accordingly, the Company may adopt the standard in either its first quarter of 2017 or its first quarter of 2018. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently evaluating the timing of its adoption and the impact of adopting the new revenue standard on its consolidated financial statements.
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 primarily consist of highly liquid corporate bonds, government agency bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Except for a single advertising agency customer noted below, 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 and six months ended June 2015, uncollectible account write-offs totaled $42,000 and $0.1 million, respectively. No uncollectible amounts were written off in the three and six months ended June 30, 2014. Prior to 2014, write-offs for uncollectible accounts were not significant. However, if circumstances change, higher than expected uncollectible accounts may result in future write-offs that are greater than the Company’s estimates. A single advertising agency accounted for approximately 11% of the Company’s accounts receivable as of June 30, 2015. No other customers accounted for 10% or more of the Company’s accounts receivable as of June 30, 2015 and December 31, 2014. The following table presents the changes in the allowance for doubtful accounts (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Allowance for doubtful accounts receivable: Balance – beginning of period $ 1,665 $ 1,266 $ 1,471 $ 1,056 Allowance for doubtful accounts receivable (17 ) 39 223 249 Doubtful accounts receivable write-offs (42 ) — (88 ) — Balance – end of period $ 1,606 $ 1,305 $ 1,606 $ 1,305
