Episodes of the Office and other NBC shows are now available for purchase at iTunes. Surely I'm not the only one who's noticed this wave in TV writing and development: with The Office alone, I can think of at a least FOUR product placement-based episodes. A trend that media analysts predicted years ago. Most recently: Chili's (2x), iPod, Evite. Any others? I'm not all that opposed to subtle hocking, as long as it's handled well.
