2012 MTV VIDEO MUSIC AWARDS
MTV, 12:00 a.m. ET
When it comes to VMA presenters and winners, the on-stage unpredictibility factor is always high. So is the performance quotient, with lots of live performers trying to outdo one another. (Personal note to Sarah: One Direction is on the bill.) Some viewers may tune in just to see the much-anticipated trailer for Breaking Dawn, Part 2, the final film in The Twilight Saga. And thanks to MTV's decision to move the award show's start time up one hour, you can see all this and Barack Obama's DNC speech.
