CBS/ hit series Person of Interest can now be watched via digital download for the first time.

The first two seasons are available - all 23 episodes from Person of Interest Season 1 and all 22 episodes from Person of Interest Season 2 - through all digital retailers, including iTunes and Amazon Instant Video.

All episodes will be available in both standard (SD) and high definition (HD). Each complete season is expected to retail for $39.99 (SD) and $49.99 (HD), with individual episodes going for $1.99/2.99.

Person of Interest executive producer J.J. Abrams said, “We are excited that new and existing fans of Person of Interest can finally catch up with the first two seasons.”

Series creator/executive producer Jonathan Nolan added, “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.”

Person of Interest returns this fall in its new Tuesday, 10 p.m. time slot after NCIS and NCIS: Los Angeles, putting three of the network's top-rated dramas back-to-back-to-back.

All three hit shows kick off their new seasons September 24.
