It's a miracle that these channels are still alive

HLN: airs nothing but true crime programming, and that's it
MTV: doesn't even show music videos anymore, all they air is some random show and the Big Bang Theory
Boomerang: People barely talk about it anymore, but for some reason is still on the air
Nickelodeon and its sister channels: You already know about them, constantly airs the Sponge on their main channel and NickToons, that one dog show that should've ended already on their preschool channel, and the superhero show and the show about a boy and his 10 sisters that also should've ended years ago
Let's not also forget to mention: Disney XD, Discovery Family Channel, Literally all Starz Channels. Let me know who else.
