I want my MTV?

I recently heard a complaint that MTV never plays music videos. It wasn't that MTV doesn't show music videos ANYMORE, but that they don't... plain and simple. I realized that the younger generation, to which many of my students belong, never had the experience of an MTV that had music playing almost constantly. There was of course a show or series playing from time to time, but one could rely on the network to air music.. a lot of music.

It seems that along with the evolution of the MTV logo, the station's content has changed just as much.  Obviously reality TV has played a large part in this derailment of music video air time.  The Real World has been an influential and lasting entity in the realm of reality TV, and it appears that MTV as well as VH1 and many other stations are feeding off of the Real World's success.  Almost any time of day, or rather all of the time, you can find many examples of reality television shows playing on more than one network.  But, what other types of programming are monopolizing air time?  There are animated shows, awards shows, game shows, sitcoms, and films aired on many of the networks supposedly dedicated to music.  How does this affect the station's branding and identity, and specifically, how does this relate to the company logo? Should a station redesign their logo based on the content aired?  Many stations have multiple logo designs or variation on design depending a particular show or genre of shows.  For example, HBO has adapted their logo many times over the years to reflect the current technology trends or specifically a show that will be played.  Youtube is a great resource for a visual history of network branding.
