Already a near-ubiquitous presence on cable and syndication, former prime-time boffo hit "Friends" is now available on iTunes. The show is one of several from the Warner Bros. library now on sale for
$1.99 an episode. Also available are episodes of "The Jetsons," "The Flintstones," and the never-aired pilot of "Aquaman." Curiously, sci-fi show "Babylon 5" is also on sale, but offered for free on
Time Warner sibling's new AOL in2TV service.
