"Sega Channel was a project developed by Sega for the Sega Mega Drive video game console. Completely revolutionary at the time of release (bar a failed attempt with the earlier Intellivision console), it was a method capable of streaming digital content to Mega Drive owners through cable television."
This makes me feel old. One of my friends had Sega channel and it was so far ahead of its time. Spent all summer playing the new games. It functioned very similarly to the new Game Pass services with how they rotated games in and out.
