Soon it will be 38 minuts.
Networks want to know why people aren't watching their shows? Well its because they have to suffor through 18 minutes of commericals. Ten years ago the average commerical time for a show was 8 minutes. That meant that you could sit back and enjoy a 50 to 52 minute program in realative peace without all of the BS interuptions.
But tell a network that they have too much time dedicated to comericals per show, and they will sight the cost of the shows to produce, and rightfully so.
So unless they can get the costs down, 38 minute 1 hour shows are going to be here sooner rather than later. When that happpens it will be far more praticle to just buy the series on DVD and watch it all at once over the course of a long night.
