Warner Bros. Home Entertainment announced on Thursday that Person of Interest has officially been made available for digital download.

All 23 episodes of Person of Interest's first season and all 22 episodes of its second season are now available for download on iTunes and Amazon Instant Video, according to a new press release by Warner Bros. The series had previously been unavailable in other forms besides television or DVD. Other services like On Demand or its official website only feature a few episodes in full.

Each season of Person of Interest can be downloaded for $39.99 in either standard or high definition on iTunes. Amazon Instant Video lists the standard definition price at $34.99 and HD at $39.99. Individual episodes are available on both platforms for $1.99 (SD) or $2.99 (HD).

"We are all excited that new and existing fans of Person Of Interest can finally catch up with the first two seasons," said J.J. Abrams, one of the show's executive producers.

Fellow executive producers Jonathan Nolan (who is also the series creator) and Greg Plageman agreed, saying, "We're thrilled that a new audience will be able to catch up on the story so far - and then buckle up for our third season."

CBS announced the premiere date for Person of Interest's third season on Monday: Tuesday, Sept. 24 at 10 p.m. The series is moving to the Tuesdays at 10 p.m. timeslot for the first time after staying at Thursdays at 9 p.m. for its first two seasons.

Person of Interest has proved to be a success for CBS, coming in as the fifth most-watched show on television for the 2012-2013 season. The show averaged 16.2 million viewers per week.

Very few details have leaked about the third season of the show. The only clue about what's to come is that Sarah Shahi has been promoted to series regular status, which was announced on May 15. Shahi plays operative Samantha Shaw, appearing in four episodes in season 2.
