In a landscape packed with legitimate streaming video heavyweights, Amazon is looking to make their Prime instant Video service more attractive with the addition of new content – this time from the sports and documentary genres.

Today, the company announced that they had reached an expanded licensing agreement to bring ESPN’s critically acclaimed, fan favorite series 30 for 30 to Prime Instant Video.

30 for 30 originally aired from October 2009 to December 2010. The series featured 30 stories from around the sports world, all taking place during the “ESPN era.” Episodes featured stories about icons like Wayne Gretzky, Muhammad Ali, and Mike Tyson, as well as compelling profiles of some lesser known figures and professional & collegiate programs. The series was then spun-off into another docu-series, ESPN Films Presents:.

Amazon Prime is also grabbing some additional sports documentaries as part of the agreement:

“We’re continuing to grow our Prime Instant Video library to provide our Amazon Prime Members with all the content they want – from feature films, to hit TV episodes to documentaries, and everything in between,” said Brad Beale, director of digital video content acquisition for Amazon. “With the addition of ESPN’s 30 for 30 series, film lovers and sports fans will have instant access to enjoy compelling sports stories from talented and thoughtful film makers including, ‘The U,’ ‘Pony Excess’ and ‘Winning Time.’”

According to Amazon, this bumps up the total offerings of Prime Instant Video to over 22,000. Back in March, Amazon inked a deal with Discovery Communications to bring Discovery Channel, TLC, and Animal Planet content to Amazon Prime. In June, they announced a deal that would bring hundreds of classic MGM movies to the service. And last month, Amazon partnered with Warner Bros. to bring shows like The West Wing and Fringe to Prime.
