Recognized as a global leader in interactive and digital entertainment, Sony Interactive Entertainment (SIE) is responsible for the PlayStation brand and family of products. PlayStation has delivered innovative products to market since the launch of the first PlayStation in Japan in 1994. The PlayStation family of products and services includes PlayStation 4, PlayStation VR, PlayStation Store, PlayStation Now and PlayStation Vue. SIE also oversees Worldwide Studios, which is responsible for developing exclusive, world-class games for PlayStation. Headquartered in San Mateo, California, SIE is a wholly-owned subsidiary of Sony Corporation and has regional headquarters in London and Tokyo. A master account is required to access the PlayStation Store. A log of all previously purchased items, known as “Download List”, records each PlayStation Store account’s complete download activity. A guest user can use their master account’s Download List to download free content or to purchase content on another console, however, a single account can only be used on up to two consoles. This was previously five, but as of November 2011, Sony reduced this to two. The most recent firmware must be installed on the console in order to access the PlayStation Store. Each master account is associated with an online virtual “wallet” to which funds can be added. This wallet is then debited when a purchase is made from the store. Money can be added to the wallet through different systems of payment, although some of these are not available in all countries. A major redesign of the PlayStation Store was announced in September 2012, bringing with it a revised navigation structure and new search system. The new store has been developed to bring game and video content together and make it easier for users to find what they are looking for. Content will be integrated into each game’s listing, rather than separate categories for items like add-ons, themes, and other downloadable content. The latest design is much less focused on text, and incorporates high-resolution artwork and smooth animations for featured content.
