This season, there is a lot of blame going around about the big drop in network broadcast ratings -- DVR time-shifting and the Internet chief among them. But how about this other angle from David Poltrack, chief research officer of CBS Corp, speaking to The Hollywood Reporter: "This was a spring where the networks were not reinvigorated with new programming as in years past. Hence, more repeats. This led to some lowering of overall viewing levels." Yes, just blame bad programming.
