Twitch is more than just thots and video games, here are some 24/7 channels I follow and what their content consists of;
MST3k - MST3k (Also contains Cinema Titanic (MST3k but slightly different), The Film Crew (Rifftrax before Rifftrax), and some Rifftrax)
Rifftrax - Bill, Kevin, and Mike from MST3k and their own movie riffing project.
Wuxia Central - Classic Kung-Fu/Samurai/Ninja movies
Old Timey Computer Show - A 24/7 stream of ye old classic computer related tv shows
OSI74 - Public Domain Movies (some with hosts some without), commercial breaks for OSI74 related content are too long and frequent, and other crap. Good background noise
Far Out Theatre - Classic Sci-Fi/Horror tv/movie
Retro Longplay - Mostly Tool Assisted runs of classic games
Starlite Drive-In - Movies, some of them actually good, from the drive-in era (Megaforce, DollMan, Trancers, The Wraith, Dirty Larry and Crazy Mary, and Near Dark being some highlights.)
Tommy Wiseau - 24/7 Tommy Wiseau content. No, seriously. He has his own 24/7 channel.
Public Domain Television - Cartoons
Other "content" I follow that is worth checking out when it's on;
Forgotten_VCR - Spliced together video mixtapes with clips from Kung-Fu/Ninja/Action/Tokusatsu/other, great community. Tues/Thurs/Sun 9:30pm Eastern. Lots of reused footage and also has the single worst depiction of Ninjitsu in film history
Cinema Insomnia - Horror Host Mr. Lobo's channel, main guy behind OSI. Schedule seems random, usually after 9pm est but days seem random
Sleazy P. Martini - Gwar's Manager, Sat and Sundays 10pm eastern. Sat is usually Japanese content and Sunday is for 3d movies. Hates Biden and Politically Correct culture.
Shout Factory TV - Movies and shit, too many built in ads for my taste. Their actual website has some pretty good free content.
UFC - TUF Tuesdays (we are on season 9), free fights, event watch-alongs, and all hosted by the grandfather of the light weight division, former champion, and UFC Hall of Famer Jens Pulver. Wife and I can't wait until they reshow UFC 1+, it's fucking amazing watching those early UFCs with chat and Jens Pulver.
