As reported by TUAW, properties from the Jim Henson Company are available on iTunes. Sadly, this does not include The Muppet Show, which was sold to Disney in 2004.

Among the shows available are the first seasons of Fraggle Rock and Farscape for $1.99 per episode. The article mentions that Farscape is difficult to find on DVD due to difficulties over home video rights (although it has been released previously).

I remember Fraggle Rock from my youth and I always enjoyed it. I remember being scared over the episode with the Terrible Tunnel. As I think about it now, I think Mokey Fraggle had the exact same voice as Rizzo the Rat from the Muppets.

So, for those who use iTunes, here is the chance to indulge yourself and purchase the first few seasons. Or, in the case of Fraggle Rock, you could just buy the DVD.
