Accounting Policies [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company generates Business and Consumer revenue. Business Revenue includes fees paid by mobile app advertisers that use the Company’s software platform (“Software Platform”), and revenue generated from the sale of digital advertising inventory of the Company’s apps (“Apps”). Consumer Revenue consists of mobile in-app purchases (“IAPs”) made by users within Apps. Business Revenue Our Software Platform provides the technology to match advertisers and third-party owners of digital advertising inventory (“Publishers”) via auctions at large scale and microsecond-level speeds. The pricing and terms for all mobile advertising arrangements are governed by the Company’s terms and conditions and generally stipulate payment terms of 30 days subsequent to the end of the month. The contract is fully cancellable at any time. For Business Revenue generated through placement of advertisements on mobile applications owned by Publishers, the Company’s performance obligation is to provide an advertiser with access to our Software Platform which facilitates the advertiser’s purchase of advertising inventory from Publishers. The Company does not control the advertising inventory prior to its transfer to the advertiser, the Company’s customer, because the Company does not have the substantive ability to direct the use of, nor obtain substantially all of the remaining benefits from the advertising inventory. The Company is not primarily responsible for fulfillment and does not have any inventory risk. The Company is an agent as it relates to the sale of third-party advertising inventory and presents revenue on a net basis. The transaction price is the product of either the number of completions of agreed upon actions or advertisements displayed and the contractually agreed upon price per advertising unit with the advertiser less consideration paid or payable to Publishers. Advertisers purchase Apps advertising inventory either through the Software Platform or through third-party advertising networks (“Ad Networks”). Revenue from the sale of advertising inventory through Ad Networks is recognized net of the amounts retained by Ad Networks as the Company is unable to determine the gross amount paid by the advertisers to Ad Networks. The Company recognizes mobile advertising revenue when the agreed upon action is completed or when the ad is displayed to users, depending on the agreed upon pricing mechanism with an advertiser or Ad Network. The number of advertisements delivered and completions of agreed upon actions is determined at the end of each month, which resolves any uncertainty in the transaction price during the reporting period. Consumer Revenue IAPs include fees collected from users for the purchase of virtual goods to enhance their gameplay experience. The identified performance obligation is to provide users with the ability to acquire, use, and hold virtual items over the estimated period of time the virtual items are available to the user or until the virtual item is consumed. The Company categorizes its virtual goods as either consumable or durable. Consumable virtual goods represent goods that can be consumed by a specific player action in gameplay; accordingly, the Company recognizes revenue from the sale of consumable virtual goods as the goods are consumed and the Company’s performance obligation is satisfied. Durable virtual goods represent goods that are accessible to the user over an extended period of time; accordingly, the Company recognizes revenue from the sale of durable virtual goods ratably over the period of time the goods are available to the user and the Company’s performance obligation is satisfied, which is generally the estimated average user life (“EAUL”). Payment is required at the time of purchase and the purchase price is a fixed amount. Users make IAPs through the Company’s distribution partners. The transaction price is equal to the gross amount charged to users because the Company is the principal in the transaction. IAPs fees are non-refundable. Such payments are initially recorded to deferred revenue. The EAUL represents the Company’s best estimate of the expected life of paying users for the applicable game. The EAUL begins when a user makes a first purchase of durable virtual goods and ends when a user is determined to be inactive. The Company determines the EAUL on a game-by-game basis. For a newly launched game that has limited playing data, the Company determines its EAUL based on the EAUL of a game that has sufficiently similar characteristics. The Company determines the EAUL on a quarterly basis and applies such calculated EAUL to all bookings in the respective quarter. Determining the EAUL is subjective and requires management’s judgment. Future playing patterns may differ from historical playing patterns, and therefore the EAUL may change in the future. The EAULs are generally between six and nine months. The Company presents taxes collected from customers and remitted to governmental authorities on a net basis.
Asset Acquisitions and Business Combinations	Asset Acquisitions and Business Combinations The Company performs an initial test to determine whether substantially all of the fair value of the gross assets transferred are concentrated in a single identifiable asset or a group of similar identifiable assets, such that the acquisition would not represent a business. If that test suggests that the set of assets and activities is a business, the Company then performs a second test to evaluate whether the assets and activities transferred include inputs and substantive processes that together, significantly contribute to the ability to create outputs, which would constitute a business. If the result of the second test suggests that the acquired assets and activities constitute a business, the Company accounts for the transaction as a business combination. For transactions accounted for as business combinations, the Company allocates the fair value of acquisition consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. Acquisition consideration includes the fair value of any promised contingent consideration. The excess of the fair value of acquisition consideration over the fair value of acquired identifiable assets and liabilities is recorded as goodwill. Contingent consideration is remeasured to its fair value each reporting period with changes in the fair value of contingent consideration recorded in general and administrative expenses. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable, and as a result, actual results may differ from estimates. In certain circumstances, the allocations of the excess purchase price are based upon preliminary estimates and assumptions and subject to revision when the Company receives final information, including appraisals and other analyses. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Acquisition-related costs are expensed as incurred. For transactions accounted for as asset acquisitions, the cost, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. The Company generally includes contingent consideration in the cost of the assets acquired only when the uncertainty is resolved. The Company recognizes contingent consideration adjustments to the cost of the acquired assets prospectively using the straight-line method over the remaining useful life of the assets. No goodwill is recognized in asset acquisitions.
Services and Development Agreements	Services and Development Agreements The Company enters into strategic agreements with mobile gaming studios (“Partner Studios”). The Company has historically allowed these Partner Studios to continue their operations with a significant degree of autonomy. In some cases, the Company bought Apps from Partner Studios and entered into service and development agreements whereby Partner Studios provide support in improving existing Apps and developing new Apps. The substantial majority of payments associated with service agreements for existing Apps are expensed to research and development when the services are rendered as the payments primarily relate to developing enhancements for the Apps. Payments for new Apps associated with development agreements are generally made in connection with the development of a particular App, and therefore, the Company is subject to development risk prior to the release of the App. Accordingly, payments that are due prior to completion of an App are generally expensed to research and development over the development period as the services are incurred. Payments due after completion of an App are generally capitalized and expensed as cost of revenue. See Note 6, “Acquisitions” for additional information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements (Issued and Not Yet Adopted) In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , to simplify the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The standard eliminates beneficial conversion feature and cash conversion models resulting in more convertible instruments being accounted for as a single unit; and simplifies classification of debt on the balance sheet and earnings per share calculation. These changes will become effective for the Company on January 1, 2022. The Company is currently evaluating the potential impact of these changes. Recent Accounting Pronouncements (Issued and Adopted) In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The ASU impacts various topic areas within ASC 740, including accounting for taxes under hybrid tax regimes, accounting for increases in goodwill, allocation of tax amounts to separate company financial statements within a group that files a consolidated tax return, intra period tax allocation, interim period accounting, and accounting for ownership changes in investments, among other minor codification improvements. The Company adopted this ASU on January 1, 2021 with no material financial statement impact upon adoption. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), which clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for equity method investments in Topic 323, and the accounting for certain forward contracts and purchased options in Topic 815. The Company adopted this ASU on January 1, 2021 with no material financial statement impact upon adoption.
