Music videos are dead? Just look up videos like Gangam Style (heck, even Friday could be used as a bizarre example) and your whole point becomes invalid.
However, I can say that television is dead in its pre-internet era format. It is simply not worth having a TV license and needing to catch your favourite shows/movies when the channel wants you to watch it. The only way TV will be able to survive the ever increasing accessibility of the internet is if it makes its transition into your computer through the internet.
