Sure, American Idol might be one big Coca-Cola and Ford advertisement. But that doesn't mean Grey's Anatomy, the once buzzworthy ABC show that's taken a nosedive in ratings and interest, has sold its soul to Madison Avenue. In what will likely turn out to be a non-scandal, the show caught flack when its season finale on Thursday, with a plotline that included the doctors freeing a young man from concrete, also aired an ad from Honda's Pilot, which showed a man trapped in concrete. Paid tie-in, or coincidence? ABC maintains the latter, as does Honda's ad agency RPA. [NYP] Below, the Honda ad.
