Really need to start uploading some of the classic video game documentaries that have been on TV over the years.
But this is Tetris: From Russia with Love, a BBC documentary from 2004 about the West's rush to obtain the rights to the most popular puzzle game of all time. And the Soviet's rather sneaky way of playing Nintendo, Mirrorsoft and Atari/Tengen off against each other.
Fantastic docudrama about the beginnings of the British computer industry and focuses on Sinclair's rivalry against Acorn computers (makers of the BBC Micro).
