Many channels have lost their original focus from when they were first started. AMC, TLC, MTV, VH1, and a bunch of others just keep their name for brand recognition purposes I would imagine. However MTV and I think MTV 2 play music videos in the early morning for 3 hours or so. I know this isn't a popular opinion, but I never watched TLC in my life, but absolutely love, My Strange Obsession, My Extreme Addiction and Here Comes Honey Boo Boo. I never in my life thought I'd watch TLC. Never in my life thought I'd watch History either until Pawn Stars first came out in 2010. A&E uses to be Arts & Entertainment. Screw that artsy fartsy high brow crap! A&E has been one of my most watched watch channels, between the Storage Wars and it's two spinoffs, Shipping Wars, Duck Dynasty, Barter Kings, The Glades, Longmire, Bates Motel and as of Monday, The Returned. I for one am so glad A&E dropped the 'Arts'.
HGTV and Food Network have turned into reality and competition show channels, the type of programming that used to be shown on them now airs on sister channels DIY and Cooking Channel. Never really watched Food Network before either but I love the Tyler Florence competition shows.
