It seems that all of television is slowly losing its identity. The History Channel doesn't cover history. TV Land clogs their airwaves with run-of-the-mill reality shows. Comedy Central gives Carlos Mencia his own show.

It must be hard to draw in the kind of ratings the average television executive expects (average=viewers who are willing to commit mass suicide if they miss a rerun of Chico and the Man) when you're anchored to one theme or genre. But it's not impossible.

One network that seems very close to giving up entirely is the Cartoon Network. According to the Los Angeles Times, CN's new lineup of live-action, reality-based programming is tanking in the ratings and rumors are swirling that the CN may drop the "C" in its name. Does the head of Radio Shack now work for the Cartoon Network?
