Electronorgtechnica
Elektronorgtechnica, also spelled Electronorgtechnica and abbreviated Elorg, was the Soviet Ministry of Software and Hardware Export that handled the initial licensing of Tetris.
The company also helped with the export of the Electronika, a Soviet brand calculator [1].
Elorg is now a privatised Russian company which up until recently has retained the rights to the Tetris trademark, when Elorg was a partner in The Tetris Company, which licenced the Tetris name to game companies, along with Alexey Pajitnov and Henk Rogers.
In 2006, games started bearing licensing from "Elorg, a Tetris Holding company" or "Tetris Holding" where "Elorg" before was shown.
