This list is long so bare with me please.
ABC - Local news mainly, also Shark Tank and What Would You Do? Extreme Makeover: Home Edition (before it was cancelled) Wipeout sometimes (LOL, I read my last comment I made about this show, it turned out to be a lot better and funnier than I expected.
)
FOX -
"Occasionally" watch Animation Domination on Sundays. That show Bob's Burgers is pretty good, it had to grow on me first though. Kitchen Nightmares, Master Chef, and Hell's Kitchen. (I'm pumped for the last two to be returning this summer.
)
MyAtlTV - If I need a good laugh I look at Jerry Springer sometimes.
TBS - If I'm having a sleepless night, I'll watch Married With Children reruns (like this morning for example)
ABC Family - Boy Meets World; used to watch Still Standing and Full House on here too.
TruTV - Only when I have nothing to do and there's not much on I'll watch Most Daring/Shocking. I also watch Impractical Jokers, I'm a fan of that show. Some of those pranks they pull on people I'm surprised they haven't been slapped or gotten their butts beaten, but it's still hilarious so I don't care.
Travel Channel - Loved watching Man v. Food, I watch the spin off Food Nation sometimes. I also sometimes watch those food paradise specials like Rib Paradise, Burger Paradise, Fried Food Paradise, etc. The Hot Dog one featured a longtime local hot dog joint here called the Varsity.
Adult Swim - I watch The Boondocks, American Dad, Aqua Teen Hunger Force, Home Movies (just like The Oblongs and Baby Blues this seems to be shown as a seasonal thing) Family Guy (if it's not an episode that sucks.) King of the Hill, Squidbillies, Robot Chicken, Delocated, Children's Hospital (sometimes, this is one of those shows where you have to like stupid/slapstick comedy) I'm not much of a fan of anime, but I used to watch Case Closed, Inuyasha, and this other show that started with a K, my memory is fuzzy on what it was about when they were on AS.
Comedy Central - Mainly watch South Park and Futurama. I used to watch MadTV when it was syndicated on there.
The channels below this is the channels I used to watch all the time when we used to have all the digital cable channels.
Boomerang - Ah, childhood memories getting to watch The Flintstones, The Jetsons, Scooby Doo again, the list can go on and on. I'm disappointed to hear they're going mainstream too, showing more current cartoons rather than just the oldies.
Nicktoons - Same as Boomerang.
The N (Teenick) - Hasn't been the same since the name change, they used to appeal to more mature audiences now they appeal to the tweens. I see Degrassi is still going strong, I used to watch that show a lot when the original cast was there, they were more hardcore on the issues, saw a recent episode out of curiosity and you can tell they're really phoning it in. I also used to watch Radio Free Roscoe, and Catlin's Way(?) I think it was called.
As a sidenote: I used to love watching Spongebob, but once I got into middle school the show got too stupid even for me and I'm someone who doesn't mind watching some stupidity in the form of comedy. I had to stop watching, I was losing too many brain cells.
EDIT: Forgot about Comedy Central.
