Sony Interactive Entertainment LLC (SIE) is a multinational video game and digital entertainment company owned by Sony. SIE primarily operates the PlayStation brand of video game consoles and products. In 1993, Sony and Sony Music Entertainment Japan jointly established Sony Computer Entertainment Inc. in Tokyo. SCE released the video game console PlayStation in Japan the following year and subsequently in the United States and Europe the year after. In 2010, SCE underwent a corporate split and established Sony Network Entertainment International (SNEI). SNEI provided gaming-related services through the PlayStation Network, including the sale of game titles and content on the PlayStation Store, as well as offering PlayStation Plus. In 2016, SCE and SNEI merged to form Sony Interactive Entertainment LLC, with its headquarters located in San Mateo, California, U.S. Since the launch of the original PlayStation console in 1994, the company has been developing PlayStation home video game consoles, accessories and services. The company expanded from Japan into North America and Europe, where it founded the branches Sony Computer Entertainment America (SCEA) in May 1995 (in Foster City, California) and Sony Computer Entertainment Europe (SCEE) in July 1995 (in Liverpool). The company quickly became Sony's main resource for research and development in video games and interactive entertainment. In April 2016, SCE and Sony Network Entertainment International was restructured and reorganized into Sony Interactive Entertainment, carrying over the operations and primary objectives from both companies. The same year, SIE LLC was established, with its headquarters in San Mateo, California. Sony Interactive Entertainment handles the research and development, production, and sales of both hardware and software for the PlayStation video game systems. SIE is also a developer and publisher of video game titles, and operates several subsidiaries in Sony's largest markets: North America, Europe and Asia. By June 2022, the company had sold more than 581 million PlayStation consoles worldwide.
