I've always wondered this, but this year, right now is the worst it's been. There are days of the week where (to me) almost nothing is on. Tuesday is a good example. But Thursdays have always been a pileup. This year seems CRAZY to me. Almost everything I follow is on Thursday now: Bones Fringe Grey's Anatomy 30 Rock CSI Burn Notice Project Runway Supernatural Vampire Diaries WTF! What is the pileup here... I'm always puzzled when networks have so many other holes all over their schedule what is the rush to pile everything on Thursday.
