Cancel your HBO subscription? Well, maybe. Looks like Apple has cut a deal to sell HBO shows through iTunes — some at a higher price point ($2.99) than they typically sell episodes of TV series. Not all the network’s shows are available (Entourage is notably absent), and everything they are selling is old material. So now the question is whether or not the network will sell new shows as they air, or whether this will basically just replicate their DVD offerings. I’m not sure I’ll be up for Hung, but I could probably go for The No 1 Ladies Detective Agency.
