Launching today on the Zune Marketplace is none other than Nickelodeon's brand-new live-action show True Jackson . The comedy, about a fifteen year old who gets to run her own fashion label, doesn't even premiere until next week -- but it's available exclusively this week on Zune and nowhere else. And it's for free.

Another quick announcement regarding new networks hitting the Video Marketplace: we've just added The N and two of their popular shows Degrassi: The Next Generation and South of Nowhere.
