Tetris began in 1984, when Alexey Pajitnov, a Soviet software engineer, was inspired by pentomino puzzles. Working at the Dorodnitsyn Computing Centre of the Academy of Sciences in Moscow, Pajitnov built the first version on an Electronika 60 computer, naming his creation "Tetris" for its use of tetrominoes and Pajitnov's love for tennis. The game spread rapidly within Soviet institutions but it was largely through unofficial copying that it gained international attention.

The complex licensing situation under the Soviet system made Tetris a hot commodity in the late 1980s, with several Western companies vying to secure rights for computer, console, and handheld versions. Key among these was Henk Rogers, who secured handheld rights by personally traveling to Moscow to negotiate directly with Soviet officials. The game's first major breakthrough came when Nintendo bundled it with its original Game Boy in 1989, significantly boosting both the Game Boy's sales and Tetris's global popularity.
However, this success was not without controversy. A separate NES cartridge release led to a notable legal dispute between Nintendo and publisher Tengen over console rights. This episode highlighted the challenges of navigating intellectual property in an era before widespread digital distribution. In 1996, Alexey Pajitnov and Henk Rogers took matters into their own hands by founding The Tetris Company, which officially manages Tetris licensing to this day.
Tetris has since appeared on nearly every major gaming platform, from arcade cabinets to modern consoles and mobile phones, and is frequently cited as one of the best-selling and most widely ported video games of all time. Competitive Tetris has grown into an organized esport: the Classic Tetris World Championship, built around the original NES version, has run since 2010.
Tetris's reach extends past gaming into documentaries, books, and a 2023 biographical feature film about the game's early licensing battles.
