HBO's always been stingy about who gets to stream its cherished TV assets but on May 21st, some of the network's vintage material will get a wider release. The company has signed a deal with Amazon to bring its classic shows, including The Sopranos, The Wire and Deadwood to Prime Instant Video members for free. If you're waiting for newer fare -- by which we mean Game of Thrones -- you'll be disappointed, but seasons of HBO's other new shows, like True Blood and Veep will arrive roughly three years after their first broadcast. As part of the deal, HBO Go will launch as an app on Amazon's Fire TV set-top box, which is due to land at some point towards the end of the year. In the meantime, however, you can prepare yourself for a May binge-a-thon by buying in plenty of snacks and bottled water.
