Basis of Presentation (Policies)	Jun. 30, 2014
Basis of Presentation	*Basis of Presentation* These accompanying financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited consolidated financial statements include Expedia, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We have eliminated significant intercompany transactions and accounts. Expedia has a variable interest in Travelocity resulting from an exclusive, long-term strategic marketing agreement entered into in the third quarter of 2013 for which we are not the primary beneficiary. Our exposure to loss under this arrangement is primarily commercial in nature, the maximum of which cannot be quantified. We have prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. We have included all adjustments necessary for a fair presentation of the results of the interim period. These adjustments consist of normal recurring items. Our interim unaudited consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2013, previously filed with the Securities and Exchange Commission.
Accounting Estimates	*Accounting Estimates* We use estimates and assumptions in the preparation of our interim unaudited consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our interim unaudited consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited consolidated financial statements include revenue recognition; recoverability of current and long-lived assets, intangible assets and goodwill; income and transactional taxes, such as potential settlements related to occupancy and excise taxes; loss contingencies; loyalty program liabilities; redeemable noncontrolling interests; stock-based compensation and accounting for derivative instruments.
Reclassifications	*Reclassifications* We have reclassified certain amounts related to our prior period results to conform to our current period presentation.
Recent Accounting Policies Not Yet Adopted	*Recent Accounting Policies Not Yet Adopted* In May 2014, the Financial Accounting Standards Board issued new guidance on revenue from contracts with customers (Topic 606). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, the new guidance specifies the accounting for some costs to obtain or fulfill a contract with a customer. The update requires an entity to apply the new guidance in one of two methods: (1) retrospectively to each prior reporting period presented, or (2) retrospectively with the cumulative effect of initially applying this update recognized at the date of initial application. The new guidance will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. We are in the process of evaluating the impact of the adoption of this new guidance on our consolidated financial statements.
