Game origin: 3rd party

Third-party games are Atari 2600 cartridges made by companies other than Atari itself. That seems normal today, but in the late 1970s nobody outside a console maker published games for its machine. The change came from Atari’s own staff. In 1979 a group of its programmers, including David Crane, Alan Miller and Bob Whitehead, left to found Activision, the first independent console game developer. Atari sued, but the case was settled by 1982, with Activision paying royalties and the idea of third-party publishing left standing. Activision also printed its designers’ names on boxes and manuals, something Atari did not do.
Other companies followed quickly. Imagic, co-founded by former Atari programmer Rob Fulop, brought out games such as Riddle of the Sphinx (1982). Toy and film companies joined in too: Parker Brothers with Tutankham, Coleco with Zaxxon, and Mattel’s M Network with BurgerTime. Starpath went further with its Supercharger add-on, which loaded games such as Communist Mutants from Space from audio cassette and raised the console’s memory from 128 bytes to over 6 KB.
Activision’s own hits remain the best-known third-party games, including David Crane’s Pitfall! (1982) and Frostbite (1983). By 1983 so many publishers had flooded shops with cartridges, of very mixed quality, that the glut is often named as one cause of that year’s video game crash.
