Presidential hopeful Barack Obama has purchased a half-hour of primetime television on CBS and NBC, during which his campaign will air a nationwide pitch to voters. The ad will run Wednesday, 29th October, at 8 p.m. — less than a week before the general election… and in Knight Rider‘s time-slot. Sadly, this means that the scheduled episode, Knight of the Living Dead — a Halloween special — has been pre-empted, and will be moved back by a week, making its appearance on 5th November.
