Sega Channel was a project developed by Sega for the 16-bit Sega Genesis console. Starting in 1994, Sega Channel service was provided to the public by Time Warner Cable and TCI, which later was acquired by the old AT&T during its cable acquisition spree that formed AT&T Broadband.
For a monthly subscription fee (usually $14.95 depending on location), along with a $25 activation fee, the subscriber would get an adapter, which plugged into the Genesis cartridge slot, and was connected to their cable television connection. The service would provide them with unlimited access to 50 games, selectable through an on-screen menu, with new games appearing every month and later every 2 weeks. The games would be downloaded in about 1 minute and play just like the retail versions. These games were organized by genre, such as Action, Fighting, Adventure, and Family. Each month, there was a special theme with originally composed music, artwork and game categories.
