Now, I never watched Farscape, but as a television addict, I was pretty familiar with the various controversies over home video rights and for the show and how difficult it is to find on DVD. I can only guess that legions of Farscape fans will be happy to be able to download first season episodes from iTunes.
As for Fraggle Rock, well, this is something I can get behind. I remember watching the show on HBO at a very early age and the theme song still makes me smile. Fraggle Rock is actually the only "Muppet" property not owned by The Walt Disney Company (in 2004 The Jim Henson Company sold the rights to The Muppets and a few other properties to Disney), and as a result it's trek to DVD has not been as drawn out (though in the US we're still only up to season 3), but despite my general feelings about buying TV shows on iTunes, I will totally indulge in the nostalgia of the Fraggles.
Now that the TV season is pretty much at a standstill (we have Project Runway and American Idol, but that's about it), watching 25 year old Muppets sing songs or watching a beloved Sci-Fi show on the Mac or Apple TV is a bit more enticing than watching the emergency season of Big Brother.
