Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation and Presentation	Basis of Consolidation and Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. Accordingly, certain notes or other information that are normally required by U.S. GAAP have been condensed or omitted if they substantially duplicate the disclosures contained in our annual audited consolidated financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Accordingly, the unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair statement of our financial position and results of operations in accordance with U.S. GAAP have been included in the accompanying unaudited condensed consolidated financial statements. Actual results could differ from these estimates and assumptions. The accompanying condensed consolidated financial statements include the accounts and operations of the Company. All intercompany accounts and transactions have been eliminated. Certain reclassifications have been made to prior year amounts to conform to the current period presentation. The Company considers events or transactions that occur after the balance sheet date, but before the financial statements are issued, to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements Inventory In July 2015, the Financial Accounting Standards Board ("FASB") issued new guidance related to the measurement of inventory which requires inventory within the scope of the guidance to be measured at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We adopted this new standard as of January 1, 2017, and applied it prospectively. The adoption of this guidance did not have a material impact on our financial statements. Recent Accounting Pronouncements Not Yet Adopted Revenue Recognition In May 2014, the FASB issued new accounting guidance related to revenue recognition. The new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance, providing a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. This guidance will be effective for fiscal years and interim periods within those years beginning after December 15, 2017. We anticipate adopting the accounting standard on January 1, 2018, using the modified retrospective method, which recognizes the cumulative effect upon adoption as an adjustment to retained earnings at the adoption date. As previously disclosed, we believe the adoption of the new revenue recognition standard may have a significant impact on the accounting for our sales of our games with significant online functionality for which we do not have vendor-specific objective evidence ("VSOE") for unspecified future updates and ongoing online services provided. Under the current accounting standards, VSOE for undelivered elements is required. This requirement will be eliminated under the new standard. Accordingly, we will be required to recognize as revenue a portion of the sales price upon delivery of the software, as compared to the current requirement of recognizing the entire sales price ratably over an estimated offering period. We expect this difference to primarily impact revenues from our Call of Duty franchise. Many of our other franchises, such as Destiny, Overwatch, World of Warcraft, and Candy Crush, are hosted service arrangements and we do not expect any significant impact on the accounting for our sales of these games. Nonetheless, this difference may have a material impact on our consolidated financial statements upon adoption of the new guidance. We are continuing to evaluate the additional impacts of this new accounting guidance on our financial statements and related disclosures. Leases In February 2016, the FASB issued new guidance related to the accounting for leases. The new standard will replace all current U.S. GAAP guidance on this topic. The new standard, among other things, requires a lessee to classify a lease as either an operating or financing lease, and lessees will need to recognize a lease liability and a right-of-use asset for their leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment for initial direct costs, lease incentives received, and any prepaid lease payments. Operating leases will result in a straight-line expense pattern, while finance leases will result in a front-loaded expense pattern. Classification will be based on criteria that are largely similar to those applied in current lease accounting. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and will require application of the new guidance at the beginning of the earliest comparative period presented. We are evaluating the impact of this new accounting guidance on our financial statements. Currently, we do not plan to early adopt this new standard. Financial Instruments In January 2016, the FASB issued new guidance related to the recognition and measurement of financial assets and financial liabilities. The new standard, amongst other things, generally requires companies to measure investments in other entities, except those accounted for under the equity method, at fair value and recognize any changes in fair value in net income. The new standard also simplifies the impairment assessment of equity investments without readily determinable fair values. The new standard is effective for fiscal years beginning after December 15, 2017, and the guidance should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity investments without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. We are evaluating the impact of this new accounting guidance on our financial statements. Statement of Cash Flows-Restricted Cash In November 2016, the FASB issued new guidance related to the classification of restricted cash in the statement of cash flows. The new standard requires that a statement of cash flows explain any change during the period in total cash, cash equivalents, and restricted cash. Therefore, restricted cash will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2018, and should be applied retrospectively. Early adoption is permitted. We are evaluating the impact, if any, of adopting this new accounting guidance on our financial statements. We expect there would be a significant impact to the condensed consolidated statements of cash flows for 2016, as this period includes, as an investing activity, the $3.6 billion movement in restricted cash resulting from the transfer of cash into escrow at December 31, 2015 to facilitate the King Acquisition and the subsequent release of that cash in 2016 in connection with the King Acquisition. Under this new standard, the restricted cash balance would be included in the beginning and ending total cash, cash equivalents, and restricted cash balances and, hence, would not be included as an investing activity in the statement of cash flows. Goodwill In January 2017, the FASB issued new guidance which eliminates Step 2 from the goodwill impairment test. Instead, if any entity forgoes a Step 0 test, an entity will be required to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit, as determined in Step 1 from the goodwill impairment test, with its carrying amount and recognize an impairment charge, if any, for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new standard is effective for fiscal years beginning after December 15, 2019 and should be applied prospectively. Early adoption is permitted. We are evaluating the impact, if any, of adopting this new accounting guidance on our consolidated financial statements.
