Well, because Obama is speaking on Tuesday, Idol is moving its performance show to Wednesday and the results show to Thursday.
Meaning week two of ABC's new Wednesday comedy block will face Idol instead of just Lost on hump day.
But, more importantly, the debuts of ABC's new Thursday night comedies are directly against the Idol machine.
So, good luck to you, In the Motherhood and relocated Samantha Who? We'll be paying more attention to your second week's ratings that your first week's... at least, I will.
