Cheers for that, I saw in SFX that Futurama was airing Stateside but I usually end up missing episode 1 of new seasons such as SGU and Fringe S3 that I had no idea was starting up!
Seeing as ITV dropped it (Entourage) and it is HBO the rights should automatically revert to Sky as part of their deal. No idea if and when they will show it though.
There seems to be some confusion about whether there is an SD version of this channel or not, or if this is the first Sky channel where HD subscribers will get access to programming before those with SD.
I remember reading one of the news stories about Sky Atlantic specifically mentioning Entourage as one of the shows to feature on it. Regardless, it's a sure bet the rights will come under Sky's deal with HBO so if not on that channel then one of the other Sky ones.
