Activision

For more than 30 years, Activision has been changing the way people play. In the process, we have built one of the largest portfolios of recognized brands and today we are one of the most valuable interactive entertainment companies in the world. Founded in 1979 as the first independent video game software developer and distributor, the company launched a series of multi-million unit selling titles in the early 1980s for the Atari 2600 including Pitfall, Kaboom! and River Raid. And since then, Activision has created some of the most iconic and memorable game experiences of all time.
