Amazon has once again expanded their Prime Instant Video service courtesy of a new agreement with NBC Universal and New Media Distribution. The company has been proactive in boosting the value of their streaming service following a successful market debut in February 2011.

The deal will add hundreds of popular TV episodes to Prime Instant Video such as prior seasons of Parks and Recreation, Parenthood, Friday Night Lights, Heroes and Battlestar Galactica, just to name a few. Members can now check out these as well as thousands of other movies and TV shows via Kindle Fire, iPad, Roku, Xbox 360, PlayStation 3 or a computer.

Unlimited streaming debuted with 5,000 movies and commercial-free television shows available for free to Amazon Prime members as part of the $79 annual membership. The company then signed a licensing deal with Viacom in February 2012 that added another 2,000 titles to the catalog. Amazon then finalized a deal with the Discovery Network the following month that delivered an additional 3,000 videos from TLC, Animal Planet, Investigation Discovery, the Science Channel and the Military Channel.

Customers now have access to over 22,000 videos using Prime Instant Video but if that isn’t enough, there’s also an expanded catalog with more than 120,000 videos available for rent or purchase that includes new release movies, day after air TV shows and classics.

Amazon customers that aren’t Prime members can sign up for a free one month trial to test the waters.
