Truth be told, we have gone to other stations (including cable stations), as a result of NBC's decision to force Jay on us, during a valuable prime time slot. I think that this exacerbates the traditional networks' problem; driving away valuable viewers - losing further market share to the cable stations.
My advice: Stick with the formula of innovation, through a variety of programming. The early years of TV invoked the fewer choices rule, but that was not damaging because there were no other video entertainment choices. Today, this is a dangerous, and heavy handed, approach, which has bottom-line consequences for the networks.
If NBC has some creative challenges, do not give up shows that can bring new viewers, like "Southland", and delay others like "Chuck" but also, consider picking up unwanted gems from other networks, like Terminator: The Sarah Connor Chronicles.
