I have noticed that it seems commercials come on all stations at the same time. When a commercial comes on, you try to jump to another station, and sure enough, there's another commercial running. Over and over again! What do these stations do? Have a meeting and decide at exactly what time they will all run commercials? But that's a whole new rant!
I recently have started that too, when a commerical comes on, I hit the mute button. It helps so much! Lots of todays commericals are just aggravating !
