Developer Family Tree

The studio lineages and alumni networks that shaped retro and modern gaming

The Atari Diaspora

When Atari's original programming team left to found Activision in 1979, they set a precedent: game developers could leave publishers and found their own studios. The studios that grew from Atari's talent — and from Activision's subsequent departures — seeded much of the American game industry.
