| Accounting Policies [Abstract] | |
| Stock-Based Compensation |
Stock-Based Compensation — Restricted Stock Units and Stock Options
Stock-based awards granted to employees, including grants of restricted stock units (“RSUs”) and stock options, are recognized as expense in the statements of operations based on their grant date fair value. We recognize stock-based compensation expense on a straight-line basis over the service period of the award, which is generally four years. We estimate the grant date fair value of RSUs at our stock price. We estimate the grant date fair value of employee stock options using the Black-Scholes valuation model. The determination of the fair value of a stock option is affected by the deemed fair value of the underlying stock price on the grant date, as well as other assumptions including the risk-free interest rate, the estimated volatility of our stock price over the term of the award, the estimated period of time that we expect employees to hold their stock options and the expected dividend rate. Stock-based compensation expense is recorded net of estimated forfeitures for only those stock-based awards that we expect to vest. We estimate the forfeiture rate based on historical forfeitures of equity awards and, as necessary, adjust the rate to reflect changes in facts and circumstances. We revise our estimated forfeiture rate if actual forfeitures differ from our initial estimates.
Stock-Based Compensation — Employee Stock Purchase Plan
In December 2013, our board of directors approved the Employee Stock Purchase Plan (“ESPP”), which was approved by our stockholders at the annual meeting in June 2014. We estimate the fair value of shares to be issued under the ESPP on the first day of the offering period using the Black-Scholes valuation model. The determination of the fair value is affected by our stock price on the first date of the offering period, as well as other assumptions including the risk-free interest rate, the estimated volatility of our stock price over the term of the offering period, the expected term of the offering period and the expected dividend rate. Stock-based compensation expense related to the ESPP is recognized on a straight-line basis over the offering period, net of estimated forfeitures.

| Deferred Revenue |
Deferred Revenue
Our deferred revenue consists principally of both prepaid but unrecognized subscription revenue and advertising fees received or billed in advance of the delivery or completion of the delivery of services. Deferred revenue is recognized as revenue when the services are provided and all other revenue recognition criteria have been met.
In addition, subscription revenue derived from sales through certain mobile devices may be subject to refund or cancellation terms which may affect the timing or amount of the subscription revenue recognition. When refund rights exist, we recognize revenue when services have been provided and the rights lapse or when we have developed sufficient transaction history to estimate a return reserve.
We were required to defer revenue for certain in application (“in-app”) mobile subscriptions that contained refund rights until the refund rights lapsed or until we developed sufficient operating history to estimate a return reserve. As of December 31, 2013, we had deferred all revenue related to these in-app mobile subscriptions subject to refund rights totaling approximately $14.2 million, as we did not have sufficient history to estimate a return reserve. Beginning in January 2014, we had sufficient historic transactional information which enabled us to estimate future returns. Accordingly, in January 2014, we began recording revenue related to these in-app mobile subscriptions net of estimated returns. This change resulted in a one-time increase in subscription revenue in the three months ended March 31, 2014 of approximately $14.2 million, as the previously deferred revenue was recognized. As of September 30, 2014, the deferred revenue related to the return reserve was not significant.

Concentration of Credit Risk
For the three and nine months ended September 30, 2013 and 2014, we had no customers that accounted for more than 10% of our total revenue. As of December 31, 2013 and September 30, 2014, we had no customers that accounted for more than 10% of our total accounts receivable.

Recently Issued Accounting Standards
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-9, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-9”). ASU 2014-9 outlines a single comprehensive model for entities to use in accounting for revenue. Under the guidance, revenue is recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard is effective for public entities with annual and interim reporting periods beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt the guidance. We are currently evaluating implementation methods and the effect that implementation of this standard will have on our consolidated financial statements upon adoption.
In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-15, Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements are issued (or available to be issued when applicable). The guidance is effective for fiscal years beginning after December 15, 2016 and for interim periods within that fiscal year. We do not expect the adoption of this guidance to have a material effect on our consolidated financial statements.
