Apple has reached a deal with another major US broadcaster for iTunes video content provision, MTV Networks.

The two companies have confirmed that popular television programming from MTV, MTV2, Comedy Central, Nickelodeon and The N is now available for purchase and download iTunes.

It’s not a selection of second-rate shows, either - it includes: “South Park,” “Dora the Explorer,” “SpongeBob SquarePants” and “Laguna Beach.”

Nickelodeon’s “Dora” becomes the first preschool program available on iTunes, while Comedy Central’s “Stand-Up” is iTunes’ first stand-up comedy program, and MTV’s “Laguna Beach” and “Real World/Road Rules Challenge: Gauntlet 2” are the first reality-based titles available on iTunes. With the addition of these 14 shows from MTV Networks, iTunes now offers over 40 TV shows for $1.99 per episode for viewing on a computer or iPod.

“The iTunes Music Store provides an innovative way for us to get our wide range of programming to our viewers,” said Jason Hirschhorn, chief digital officer, MTV Networks. “MTV Networks’ brands feature some of the most popular programs in television today, and iTunes allows us to connect our content to even more audiences. We’re committed to having our programming on multiple platforms as our audience’s media consumption behavior evolves.”

“Video has proven to be a smash hit on iTunes with over eight million videos sold,” said Eddy Cue, Apple’s vice president of iTunes.

The new programming spans MTV Networks’ varied brands and includes full seasons of hits from each show.
