Summer TV?

SO I was sitting at a news meeting yesterday and the station manager came over to talk about ratings and such. He said, "You guys aren't going to believe the top two shows on TV right now." He was right. I was anticipating one or more of the major networks to have at least one of top summer shows...I mean they dominate the fall months still. The number one show on TV right now: The Closer. The number two show: Hannah Montana. Hannah Montana also owns at least four more spots on the top 15 list. The networks don't make a dent in the lineups. Hell even movies aired on the Disney Channel beat out the big three. So I ask myself...and in turn you...is it the programming, or the fact that in the summer the big kids go out to play living the little ones in charge of the TV? I know I don't watch nearly as much TV in the summer...but does that mean that programming has to suffer this much? I might watch if the top program wasn't "The Next Best Thing" or "So You Think You Can Dance?" That is my question/rant for the morning. I could go into more detail but I am busy watching the Today show...
