Yah - I can remember when it started - I was working in the old man's record store at the time (and we'd just hung TVs on the wall to show it, turned them on all at once.)
Originally? Cool. Music videos (real music!) no commercials.
Later? Kinda cool. Music started taking a bad direction, game shows were silly.
Still later? I didn't bother watching the game shows or the ersatz "reality" shows (never have,) but I did enjoy B&B, The Maxx, and Aeon Flux.
Now? I don't think we even get it. At least, I've not bothered to look for it. Not worth the trouble.
VH1 came out about the time MTV started heading downhill - watched it while it was videos, but they took the same path as MTV and I probably lost interest in it fifteen years ago...
(Oh - and I do have copes of Beavis & Butthead, The Maxx, and Aeon Flux... Probably the only thing salvageable from MTV anymore...)
