Barack Obama is buying a half hour ad on October 29 to talk to Americans in the week before the election. He's roadblocking this ad -- that is, buying it on a string of networks at the same time so anyone watching any number of networks at that time will see his speech. This could take place during Game Six of the World Series (assuming there is a Game Sxix) and FOX has just said it will push the start time of the game back (and skip its usual half hour of blather beforehand) in order to air the Obama ad. Amazing.
NOTE: They keep mentioning he is buying the ad on CBS and NBC and FOX. Why not ABC?
