These numbers speak for themselves: these are actual runtimes of half-hour episodes from over the years. As you go down the list, the erosion of our television shows becomes obvious, with the disparity between the length of the longest (26:50) and shortest (18:41) show more than eight minutes.
As the trend continues, I won't be surprised if sitcoms go below the 15-minute mark in the next ten years. The networks are upset about DVRs and Dish's The Hopper, but they're the ones who have necessitated fast-forwarding, or "hopping" through commercial breaks.
