As expected, a number of popular HBO shows have made their way on to Amazon Prime Instant Video. The initial offerings are mostly made up of older shows like Deadwood, The Wire, Rome, Six Feet Under, Flight of the Conchords and The Sopranos, but there are also select seasons of current shows like Boardwalk Empire, True Blood and Treme.

Alongside some of HBO's most popular shows, the $99 a year entry fee to Amazon's instant video service now also comes with access to a number of HBO miniseries, documentaries, movies, and comedy specials from Louis CK, Ellen DeGeneres, Lewis Black and others.

While it may be some time before we see newer HBO shows, Amazon has struck an ongoing licensing deal with the company that will see more content added in the coming years. Titles like Girls, Newsroom and Veep are all expected to make their way to Amazon Instant Video sometime throughout the life of the deal, according to Amazon. Initial estimates put newer titles hitting Amazon's service some three years after airing on HBO.

While this is content most people have aleardy seen and/or purchased previously, it can be a nice way for Instant Video subscribers to catch up on older episodes and adds some nice value to Amazon's service after the $20 price hike back in March.

As we previously reported, the partnership will extend to Amazon's Fire TV platform as well, where HBO Go will become available later this year.
