Online shopping addicts beware: A TiVo-Amazon partnership will soon allow TiVo customers to purchase items via Amazon.com without ever leaving the couch.

With Product Purchase, TiVo users can click over to Amazon on the TV screen using their remote controls and purchase items discussed on a certain TV show. Want a few of Oprah's favorite things? Intrigued by a book mentioned on The Colbert Report? Click over to TiVo's Universal Swivel Search function, find the items, and purchase them directly.

The service launches Tuesday and is available on broadband-connected Series 2, Series 3, and TiVo HD DVRs. It will launch in conjunction with four specific TV shows.

Those shows include the Oprah Winfrey Show, The Colbert Report, The Ellen DeGeneres Show, and Burn Notice. But if a "product is seen or advertised on any TV show or network, and sold by Amazon.com it can be merchandised to viewers through TiVo," Evan Young, director of broadband services for TiVo, said in a statement.

TV advertisers will be able to merchandise specific products through TiVo advertising features such as Interactive Tags, Gold Star Sponsorships, and Program Placement, TiVo said.

"If a guest on the Daily Show or Oprah has a new book, CD, or DVD out, you can purchase it on Amazon.com using your TiVo remote without missing a second of TV, whether the viewer is watching live or recorded," Young said. "The viewer with an impulse can buy right away and no longer needs to remember to do so the next time they are at their PC."

Viewers can purchase the item immediately or add it to their Amazon.com shopping cart for later checkout.

Scott Merlino, senior manager of business development at Amazon, said the project will let advertisers "break free of traditional shopping channel limitations and reach a specific, targeted audience regardless of which network or show they are watching."

"Now, a record label can merchandise and sell a new artist's CD on a show where the music is featured, or a publisher can merchandise an author's book during a talk show when the author appears as a guest -- the marketing possibilities are endless," Merlino said.
