Activision is an American video game publisher and it is based at Santa Monica, California. It has been serving as the publishing business for the parent company, Activision Blizzard and has a large number of subsidiary studios. It is known as one of the biggest third-party video game publishers in this world and has been the top United States publisher in the year 2016. It was initially established as Activision, Inc. in October 1979 at Sunnyvale, California by Atari game developers. Activision is known as the first independent, third-party console video game developer.
The 1983 video game crash where many companies tried to follow in Activision’s footsteps without expertise of the founders of Activision hurt the position of Activision in console games and forced them to diversify into games for home computers which also included the acquisition of Infocom. After the shift in management, Bruce Davis replaced Jim Levy as the CEO and the company was renamed as Mediagenic. This later branched out into many business software applications. Mediagenic later fell into debt and it was bought by Bobby Kotick and a small group of investors for US$500,000 in the year 1991.
Kotick did a full rework of the company for covering the debts by dismissing most of the staff, moved the company to Los Angeles and reverted to the name Activision.
