	1.     Description of Business and Basis of Presentation
	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 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 Prospectus filed pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”) with the SEC on August 7, 2013 (the “Prospectus”). The condensed consolidated balance sheet as of December 31, 2012, 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 primarily of normal recurring adjustments) necessary for the fair statement of the interim periods stated.
	In July 2013, the Company's board of directors and stockholders approved an amendment to the amended and restated certificate of incorporation. The amendment provided for a 1-for-6 reverse stock split of the outstanding common stock, effective July 24, 2013. Accordingly, (i) every six shares of common stock have been combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding option or warrant to purchase common stock is exercisable, as the case may be, have been proportionately decreased on a 6-for-1 basis, (iii) the exercise price for each such outstanding option or warrant to purchase common stock has been proportionately increased on a 1-for-6 basis, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced on a 6-for-1 basis. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-6 reverse stock split. The Company has agreed to pay cash in lieu of any fractional shares to which a holder of common stock would otherwise be entitled as a result of the reverse stock split.
	On August 12, 2013, the Company closed the initial public offering (the “IPO”) of its common stock pursuant to a registration statement on Form S-1. In the IPO, the Company sold 5,125,000 shares of common stock at a public offering price of $9.00 per share. Net proceeds were approximately $40.0 million, after deducting underwriting discounts and commissions of $3.2 million and offering expenses of $2.9 million, of which $0.1 million was unpaid as of September 30, 2013. Upon the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 21,840,537 shares of common stock and all outstanding warrants to purchase convertible preferred stock converted into warrants to purchase 53,983 shares of common stock.
	Principles of Consolidation
	These 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.

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.
	Recent Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued amended standards that provided explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance becomes effective on January 1, 2014; it should be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The Company is currently assessing the impact of this new guidance.
	Concentrations and Other Risks
	Financial instruments that subject the Company to a concentration of credit risk consist of cash and cash equivalents and accounts receivable. Cash and cash equivalents are deposited with one domestic and four 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.
	Except for the Company’s single largest 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 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. Historically, write-offs for uncollectible accounts have not been significant. However if circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates.
	One advertising agency customer accounted for 23% and 16% of the Company’s revenue for the three months ended September 30, 2013 and 2012, respectively and accounted for 20% and 19% of the Company’s revenue for the nine months ended September 30, 2013 and 2012, respectively. The same customer accounted for 25% and 28% of the Company’s accounts receivable as of September 30, 2013 and December 31, 2012, respectively.

Note 3 - Fair Value of Financial Instruments	9 Months Ended

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. Based on the borrowing rates currently available to the Company for debt with similar terms, the carrying value of the borrowings under the Company’s Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”) approximate fair value (using Level 2 inputs).
	Prior to the conversion of the Company’s warrant liability on August 12, 2013, its preferred stock warrants were recorded at fair value. On August 12, 2013, upon the closing of the Company’s IPO, the warrants were converted from warrants to purchase preferred stock to warrants to purchase common stock and the liability at their then fair value of $0.4 million was reclassified to additional paid-in capital. Prior to this date, all changes in the fair value of the warrants were recorded in other income (expense), net in the accompanying unaudited condensed consolidated statements of operations. The Company recorded other income of $35,000 and other expense of $0.1 million in the three and nine months ended September 30, 2013, respectively, and recorded other expense of $9,000 and $6,000 for the three and nine months ended September 30, 2012, respectively, related to the fair value adjustment of its warrants.
	The following tables present information about the Company’s assets measured at fair value on a recurring basis as of September 30, 2013 and December 31, 2012 and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands):

	5.     Acquisition
	On December 28, 2012, the Company completed the acquisition of Crowd Science, Inc. ("Crowd Science"), a technology company providing online digital media properties audience measurement, ad targeting and web analytics. All of the share capital for Crowd Science was acquired in exchange for $1.1 million in cash and 2,000,000 shares of Series D-1 convertible preferred stock valued at $3.3 million, for a total consideration of $4.4 million. The Company held back $49,000 in cash and 66,666 shares of Series D-1 convertible preferred stock classified as contingent consideration to non-employee shareholders at the closing of the acquisition until the second anniversary of the closing date for general representations and warranties as well as performance conditions tied to the expected continuing employment of key employees. The goodwill generated from the Company's business combination is primarily related to expected synergies. The goodwill is deductible for U.S. federal income tax purposes.
	The performance conditions were no longer capable of being met as of September 30, 2013. As such, the Company accounted for the settlement of this contingent consideration within equity. The Company is accounting for the withheld shares as 66,666 shares of treasury stock.
	The acquisition was accounted for as a business combination in accordance with Accounting Standards Codification (“ASC”) Topic 805 with the results of the acquired company's operations included in the consolidated financial statements starting on December 28, 2012. The key factors underlying the acquisition were to acquire technology that would enhance audience reach and targeting across all video devices.
	The following unaudited pro forma financial information presents the results of operations of the Company and the acquired company as if the acquisition had occurred on January 1, 2012. The pro forma financial information is provided for comparative purposes only and is not necessarily indicative of what the actual results would have been had the acquisition occurred at the beginning of the year ended December 31, 2012 (in thousands, except per share data):

	7.     Borrowings
	In September 2009, the Company entered into a Loan Agreement with SVB. The Loan Agreement provides for borrowings up to $1.0 million to finance purchases of equipment through December 2013. Borrowings against the line of credit bear interest at a fixed rate of 8% per annum and require 36 equal monthly installments of principal and interest. The Company had approximately $31,000 and $0.2 million of borrowings outstanding under this line of credit as of September 30, 2013 and December 31, 2012, respectively. Borrowings under the Loan Agreement are collateralized by the equipment financed under the Agreement.
	In February 2010, the Company entered into a Loan and Security Agreement (the "Credit Agreement") with SVB for the purpose of financing its accounts receivable balance. The Credit Agreement was amended and restated in March 2011 and May 2012 and provided for a revolving line of credit with maximum borrowings of up to $20.0 million and was collateralized by substantially all of the assets of the Company. The borrowings under the line of credit bear interest at the bank's prime rate plus 0.50%. If the Company borrowed more than $5.0 million, the Company would have been required to maintain an adjusted quick ratio of 1.5 to 1.0. The Credit Agreement required the Company to comply with various other financial and reporting covenants. As of December 31, 2012, the Company had no borrowings outstanding under this line of credit. The Credit Agreement expired on May 3, 2013 and the Company did not renew it.

	9.    Warrants
	In conjunction with a lease agreement, the Company issued warrants to purchase 24,838 shares of Series A-2 preferred stock on December 31, 2006. These warrants have an exercise price of $1.2078 per share and expire in December 2018.
	In conjunction with the Loan Agreement disclosed in Note 7, the Company issued warrants to SVB, to purchase 29,145 shares of Series C preferred stock, of which 14,573 shares were issued in September 2009 and 14,572 shares were issued in January 2010. These warrants have an exercise price of $1.7155 per share and expire in January 2017.
	On August 12, 2013, upon the closing of the Company’s IPO, the warrants were converted from warrants to purchase preferred stock to warrants to purchase common stock and the liability at their then fair value of $0.4 million was reclassified to additional paid-in capital. Prior to the conversion of our warrant liability on August 12, 2013, the Company’s preferred stock warrants were recorded at fair value. Changes in the fair value of the warrants were recorded in other income (expense), net in the accompanying unaudited condensed consolidated statements of operations. The Company recorded other income of $35,000 and other expense of $0.1 million for the three and nine months ended September 30, 2013, respectively, related to changes in the fair value adjustment of its warrants. The Company recorded other expense of $9,000 and $6,000 for the three and nine months ended September 30, 2012, respectively, related to changes in the fair value adjustment of its warrants.

	Initial Public Offering
	On August 12, 2013, the Company closed the IPO pursuant to a registration statement on Form S-1. In the IPO, the Company sold 5,125,000 shares of common stock at a public offering price of $9.00 per share. The aggregate offering price for shares sold in the offering was approximately $46.1 million. Net proceeds were approximately $40.0 million, after deducting underwriting discounts and commissions of $3.2 million and offering expenses of $2.9 million, of which $0.1 million was unpaid as of September 30, 2013. Upon the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 21,840,537 shares of common stock and the carrying value of $76.2 million is included in additional paid-in capital on the condensed consolidated balance sheet as of September 30, 2013.

	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% shareholder, 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 will serve 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 compensation committee of 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. The Company has reserved 2,000,000 shares of its common stock for issuance under the 2013 Plan, and shares reserved for issuance will 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.
	The following table summarizes option award activity:
			Number of			Weighted-		Weighted-		Aggregate
			Shares			Average		Average		Intrinsic
			(in thousands)			Exercise		Remaining		Value
						Price		Contractual		(in thousands)
								Life

	The weighted average grant date fair value of options granted was $6.41 and $2.76 in the three months ended September 30, 2013 and 2012, respectively and $5.89 and $2.70 for the nine months ended September 30, 2013 and 2012, respectively. Prior to the Company’s IPO, aggregate intrinsic value represented the difference between the Company’s estimated fair value of its common stock and the exercise price of outstanding, in-the-money options. After the Company’s IPO, aggregate intrinsic value represented 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 $0.9 million and $34,000 for the three months ended September 30, 2013 and 2012, respectively, and was $1.3 million and $3.4 million for the nine months ended September 30, 2013 and 2012, respectively.
	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 has reserved 500,000 shares of its common stock for issuance under the 2013 Purchase Plan and shares reserved for issuance will 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. There were no shares purchased by employees under the Company’s ESPP for the three and nine months ended September 30, 2013.
	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 September 30,												Nine Months Ended September 30,
			2013							2012					2013				2012
Expected term (in years)			5.51			-		6.08				6.01			5.51	-	6.12		5.93	-	6.01
Volatility						80%						49%				80%			49%	-	65%
Risk-free interest rate			1.50%			-		1.72%		0.76%		-	0.92%		1.02%	-	1.72%		0.76%	-	1.07%
Dividend yield						—						—				—				—
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 September 30,					Nine Months Ended September 30,
		2013			2012		2013		2012
Expected term (in years)			0.48			—		0.48		—

	11.  Net Income (Loss) per Share
	Basic and diluted net income (loss) per common share is presented in conformity with the two-class method required for participating securities. Immediately prior to the closing of the Company’s IPO, all shares of outstanding convertible preferred stock automatically converted into shares of the Company’s common stock. Prior to the conversion of the convertible preferred stock, holders of Series A-1, Series A-2, Series B, Series C, Series D and Series D-1 convertible preferred stock were entitled to receive noncumulative dividends when and if declared at the annual rate of 8% ($0.10500, $0.20130, $0.54760, $0.28592, $1.00496 and $1.31370 per share per annum, respectively) payable prior, and in preference to, any dividends on any shares of the Company’s common stock. In the event a dividend was paid on common stock, the holders of Series A-1, Series A-2, Series B, Series C, Series D and Series D-1 convertible preferred stock were entitled to a proportionate share of any such dividend as if they were holders of common stock (on an as-if converted basis). The holders of convertible preferred stock did not have a contractual obligation to share in the losses of the Company, accordingly, basic and diluted net income (loss) per share has not been computed using the two class method.
	Under the two-class method, net income (loss) attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income (loss) less current period convertible preferred stock non-cumulative dividends, between common stock and convertible preferred stock. In computing diluted net income (loss) attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share attributable to common stockholders is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options using the treasury stock method.
	The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share data):

	During the three months ended September 30, 2013 and 2012 and the nine months ended September 30, 2013 and 2012, the Company recorded costs for a digital media property owner that was also an investor in the Company's Series D-1 convertible preferred stock, of $0.3 million, $0.2 million, $0.8 million, $0.5 million, respectively, associated with the acquisition of ad inventory. At September 30, 2013 and December 31, 2012, the Company had $0.3 million and $0.2 million, respectively for this related party included in accrued digital media property owner costs in the accompanying condensed consolidated financial statements. In addition, we have engaged Nielsen for a variety of media services including the provision and evaluation of data and analysis regarding marketing and demographic targets, television viewing behavior, online and Internet usage, ad view counts and TV/Internet share shift analysis. Mitchell Habib, a member of our board of directors, is the Chief Operating Officer of Nielsen. During the three months ended September 30, 2012 and the nine months ended September 30, 2013 and 2012, the Company made payments to Nielsen of $0.1 million, $0.3 million and $0.3 million, respectively. During the three months ended September 30, 2013, the Company did not make any payments to the vendor. At September 30, 2013 and December 31, 2012, the Company had no amounts due for the vendor.

Segment Reporting [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	13.   Segments
	The Company considers operating segments to be components of the Company in which separate financial information is available that is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker for the Company is the Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, the Company has determined that it has a single operating and reportable segment. The Company and its Chief Executive Officer evaluate performance based primarily on revenue in the geographic locations in which the Company operates. The following table summarizes total revenue generated through sales personnel employed in the respective locations (in thousands):
		Three Months Ended September 30,				Nine Months Ended September 30,
		2013		2012		2013		2012

	Total revenue	$	36,157	$	26,010	$	97,089	$	71,275
	The Company’s long-lived assets are primarily located in the United States and not allocated to any specific region. Therefore, geographic information is presented only for total revenue.

Accounting Policies [Abstract]	'
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]	'
	Recent Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued amended standards that provided explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance becomes effective on January 1, 2014; it should be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The Company is currently assessing the impact of this new guidance.
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 and accounts receivable. Cash and cash equivalents are deposited with one domestic and four 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.
	Except for the Company’s single largest 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 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. Historically, write-offs for uncollectible accounts have not been significant. However if circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates.
	One advertising agency customer accounted for 23% and 16% of the Company’s revenue for the three months ended September 30, 2013 and 2012, respectively and accounted for 20% and 19% of the Company’s revenue for the nine months ended September 30, 2013 and 2012, respectively. The same customer accounted for 25% and 28% of the Company’s accounts receivable as of September 30, 2013 and December 31, 2012, respectively.
