The history of PONG games and derivates just started, would spread all over the globe, and die in the early 1980s. In the USA, it started on May 1972 with the Magnavox Odyssey (first home video game) and Atari in November 1972 (their first PONG arcade game). Atari's game was quickly copied and improved in 1973. Later in 1975, home video games became popular and were sold by numerous companies.
