This news is going to upset fans of Knight Rider. Both of them.

Senator Barack Obama has bought 30 minutes of airtime on NBC on October 29 at 8pm, which means that he'll knock Knight Rider off the air for the night (no idea what NBC will put in the other 30 minutes, perhaps a repeat). Obama has also bought 30 minutes at the same time on CBS, which means that The New Adventures of Old Christine will air at 8:30 and the new Jay Mohr sitcom Gary Unmarried won't be on that night at all. FOX won't air the ads because of the World Series, and ABC said they'd air it only if Obama would dance with someone and/or get an extreme makeover.

And yes, if you're curious, the networks have of course offered Senator John McCain the same deal, though analysts aren't sure if he has the money to afford the 30 minute ads.

I don't mind this move because I don't watch either show. Now, if he were to interrupt 30 Rock or Mad Men or Heroes, well, then we'd have a problem.
