I'm afraid you're right. MTV USA promotes a sort of debased trash that no sane person would want in their home, either here or abroad. It's quite perverse.
But MTV produces separate regional feeds for Europe, SE Asia, and South Asia which do NOT stoop to the same carnal level as MTV USA. Entirely different formats, "DJs", music, and cultural approaches.
MTV Europe still has the semi-artsy sense of the original MTV; MTV Singapore is cutesy adolescent (the most daring thing I saw recently was an MTV Singapore host asking to be kicked in the butt in public, and everyone was wearing their clothes); MTV India is into silliness and yuk yuks.
Unfortunately, the trashiest and most perverse MTV material is reserved for American youth, by huge and inarguable margin. Along with the unique and healthy dose of gangsta rap which is not shown on any other MTV regional outlet.
Interesting. I wonder why.
