Amazon and TiVo are teaming up to make short work of the infomercial. Well, that's not exactly how the companies are promoting the new "Product Purchase" feature. TiVo customers will be able to order items from Amazon using their TV, TiVo, and remote control. No web browser or computer necessary. And no need to place your order in the next 15 minutes to get a free bonus gift.

Users will see links to products popping up in various parts of the TiVo interface. For example, if you're looking at a listing for a late night talk show, you might find links to buy books, CDs, or DVDs from that night's guests.

The advantage of ordering from TiVo is that you can make impulse purchases while watching a program, while recording the rest of the program in the background for later viewing. Of course, as anyone with a penchant for picking up candy and trashy magazines in the grocery store checkout lane can tell you, it'd be nice to have the choice to opt-out of the service in order to avoid impulse purchases.
