Microsoft and 20th Century Fox have announced that starting this Monday the 2nd of September, the first two seasons of the popular american animated tv show Family Guy will be available on Xbox Live Marketplace.

Xbox 360 owners will be able to purchase each of the episodes from the first two seasons as well as the straight-to-DVD film “Family Guy Presents Stewie Griffin: The Untold Story” for 160 Microsoft points, or about $2, which is comparable with the pricing of TV episodes on iTunes and other VOD platforms.

“Family Guy” represents the first Fox product to make it onto Xbox, which lacks an overall deal with the News Corp.-owned studio. In the battle of the electronic sell-through outlets, score one for Xbox over main rival iTunes, which hasn’t yet landed rights to “Family.”

“This is our first one,” said Jamie McCabe, executive vp at 20th Century Fox. “We hope to have other content on there, but right now with the launch of ‘Halo 3’ and the launch of the new season of ‘Family Guy’ coming out, the timing really worked well for this one.”

In addition to being its initial foray into Xbox, this also is first time the Seth MacFarlane-created series about the irreverent Griffin clan has been available for downloads on any platform, McCabe said.

Unfortunately since the Xbox Live Marketplace (XBLM) is still only available in the US, owners of Xbox 360 consoles outside the US will not be able to enjoy the same 20th Century Fox offering. Hopefully that will all change by the end of 2007 though!
