I watch a lot of TV shows while riding my exercise bike, using the DVR to skip through all the commercials. I start the bike when I start the show, so except for the time it takes me to skip commercials, which might vary a little, I get a good idea of how long a show actually runs by looking at my bike timer when the show ends. Before the start of the year, "hour" dramas seemed to run between 47 and 48 minutes, by my inexact measurement. This year, the second-half-of-the-season shows I watch all seem to run about 45 minutes (Fringe, Ugly Betty, Heroes, for example). Doesn't seem to matter which network, either. They all seem to be a couple of minutes shorter. Has anyone else noticed this? Have there industry changes in program lengths that started this year?
