"Korobeiniki" is a nineteenth-century Russian folk song that tells the story of a meeting between a korobeinik (peddler) and a girl, describing their haggling over goods in a metaphor for seduction.

Tetris is a puzzle video game created in 1985 by Alexey Pajitnov, a Soviet software engineer. It has been published by several companies for multiple platforms, most prominently during a dispute over the appropriation of the rights in the late 1980s. After a significant period of publication by Nintendo, in 1996 the rights reverted to Pajitnov, who co-founded the Tetris Company with Henk Rogers to manage licensing.
