NBC has inked a deal with Apple to become the second network to sell television shows a la carte on Apple’s online iTunes store. More than 300 episodes from about a dozen prime time, cable, late-night and classic TV shows are now available for $1.99 apiece, viewable on computers or downloadable on the latest, video-capable iPod.

The programming spans from the 1950s to the present, including shows from “Alfred Hitchcock Presents,” “Dragnet,” USA Network’s “Monk,” the Sci-Fi Channel’s “Battlestar Galactica,” and NBC’s hit series “Law & Order.” Sketches from “The Tonight Show with Jay Leno” and “Late Night with Conan O’Brien” are also for sale.

I’m guessing that’s the toe-in-the-water list and we’ll quickly see last night’s stuff on iTunes in the morning. One more example of that Long Tail. Those programs were just gathering dust and now they’ll generate dollars.
