On July 31st, 1989, North America got to experience the newest hardware from Nintendo. However, it wasn’t a home console, like the NES. It was a handheld, the Game Boy. The Game Boy became very successful, with it and the Game Boy Color eventually selling a total of 118,000,000 units.
Games that were released for the Game Boy on launch, such as Super Mario Land and especially Tetris, also sold well. In fact, there were 18,000,000 copies of Super Mario Land sold, more than Super Mario Bros. 3 did on the NES. The Game Boy remained in production after its successor, the Game Boy Advance, released. It was discontinued in 2003. A tweet relaying the news is down below.
