After breaking ties with iTunes a few days ago, NBC will begin offering downloads of their shows through Amazon’s Unbox service — apparently because it’ll make them more money.

The media conglomerate, part of General Electric, said yesterday that Amazon had agreed to give it something that Apple would not: greater flexibility in the pricing and packaging of video downloads. As a result, NBC Universal said it had agreed to sell a wide variety of television programming on Amazon’s fledgling Unbox download service, including the drama “Heroes” and the comedies “The Office” and “30 Rock.” Episodes will be available on Unbox the day after they are shown.

While Amazon is still working to determine pricing, Unbox typically charges more for newer releases than for older ones. Unbox also gives consumers more options, including whether to rent a movie for $3.99 or buy a download for $14.99. Amazon agreed to offer promotions, including a 30 percent discount when buying full seasons of television shows.

Apple sells episodes of television shows for a flat $1.99, with movies priced at $9.99.

We’ll see how this goes.
