Description of Business	Description of Business Activision Blizzard, Inc. is a leading global developer and publisher of interactive entertainment content and services. We develop and distribute content and services on video game consoles, personal computers (“PC”s), and mobile devices. We also operate esports leagues and offer digital advertising within our content. The terms “Activision Blizzard,” the “Company,” “we,” “us,” and “our” are used to refer collectively to Activision Blizzard, Inc. and its subsidiaries. The Company was originally incorporated in California in 1979 and was reincorporated in Delaware in December 1992. In connection with the 2008 business combination by and among the Company (then known as Activision, Inc.), Vivendi S.A, and Vivendi Games, Inc., pursuant to which we acquired Blizzard Entertainment, Inc. (“Blizzard”), we were renamed Activision Blizzard, Inc. On February 23, 2016, we acquired King Digital Entertainment plc, a leading interactive mobile entertainment company ("King"), by purchasing all of its outstanding shares. Our Segments Based upon our organizational structure, we conduct our business through three reportable segments, as follows: (i) Activision Publishing, Inc. Activision Publishing, Inc. (“Activision”) is a leading global developer and publisher of interactive software products and entertainment content, particularly for the console platform. Activision primarily delivers content through retail and digital channels, including full-game and in-game sales, as well as by licensing software to third-party or related-party companies that distribute Activision products. Activision develops, markets, and sells products primarily based on our internally developed intellectual properties. Activision also includes the activities of the Call of Duty League, a global professional esports league with city-based teams for Call of Duty^®. Activision’s key product franchise is Call of Duty, a first-person action title for the console and PC platforms and, following the October 1, 2019 launch of Call of Duty: Mobile, the mobile platform, including for Google Inc.’s (“Google”) Android and Apple Inc.’s (“Apple”) iOS. (ii) Blizzard Entertainment, Inc. Blizzard is a leading global developer and publisher of interactive software products and entertainment content, particularly for the PC platform. Blizzard primarily delivers content through retail and digital channels, including subscriptions, full-game, and in-game sales, as well as by licensing software to third-party or related-party companies that distribute Blizzard products. Blizzard also maintains a proprietary online gaming service, Blizzard Battle.net^®, which facilitates digital distribution of Blizzard content and selected Activision content, online social connectivity, and the creation of user-generated content. Blizzard also includes the activities of the Overwatch League^TM, the first major global professional esports league with city-based teams.

(iii) King Digital Entertainment King is a leading global developer and publisher of interactive entertainment content and services, primarily for the mobile platform, including for Google’s Android and Apple’s iOS. King also distributes its content and services on the PC platform, primarily via Facebook. King’s games are free to play; however, players can acquire in-game items, either with virtual currency or real currency, and we continue to focus on in-game advertising as a growing source of additional revenue. King’s key product franchise is Candy Crush™, which features “match three” games for the mobile and PC platforms. Other We also engage in other businesses that do not represent reportable segments, including the Activision Blizzard Distribution (“Distribution”) business, which consists of operations in Europe that provide warehousing, logistics, and sales distribution services to third-party publishers of interactive entertainment software, our own publishing operations, and manufacturers of interactive entertainment hardware. Destiny Franchise In 2010, Activision entered into an exclusive relationship with Bungie, Inc. (“Bungie”) to publish games in the Destiny franchise. Effective December 31, 2018, Activision and Bungie mutually agreed to terminate their publishing relationship related to the Destiny franchise. As part of this termination, Activision agreed to transfer its publishing rights for the Destiny franchise to Bungie in exchange for cash and Bungie’s assumption of on-going customer obligations of Activision. Going forward, Activision no longer has any material rights or obligations related to the Destiny franchise. As a result of the agreement to terminate the relationship, the Company recognized revenues of $164 million and GAAP operating income of $91 million for the year ended December 31, 2018. Activision no longer has any material rights or obligations related to the Destiny franchise.
