It was an interactive cable tv experiment up in Columbus, OH in the late 70s-early 80s and it features a ton of bonkers live+pre produced shows where the audience votes on what happens. Some of the programing is so much more interactive than the other interactive TV experiments due to the fact that the shows could change dramatically due to audience choice, much more so than even a lot of FMV game/choose your own adventure games/interactive movies. Audiences could choose a shows theme, characters, hell there was even a tabletop RPG show where the dungeon master bantered live with the protagonist about the audiences poor choices.
There's a bunch of it on YouTube and archive, I highly recommend taking a look if you're into old interactive entertainment experiments
