Amazon's Prime Instant Video streaming service is continuing to fill out its selection with today's announcement that subscribers will be able to watch episodes from prior seasons of many A&E, History, Lifetime, and Bio shows. The company doesn't specify which shows will be included, but it says that "popular series" like Pawn Stars, Storage Wars, and Dance Moms will be. The content licensing deal comes only a few months after Neflix's negotiations with A&E fell through, meaning the Amazon Prime Instant Video, for now, is the only place you can get many of these shows as part of a streaming subscription. A&E and its sister channels already allow free access to their shows online, but that only includes shows from the current season — you'll need to sign up for a subscription service for past episodes. With the latest edition, Amazon's $79-per-year Netflix competitor now claims to have 33,000 TV shows and movies available for Prime subscribers to watch for free, though it's worth noting that number counts individual episodes, not series.
