Amazon has just landed another exclusive content deal for its Prime Instant Video service. This time it’s the upcoming CBS drama Under the Dome.

Here are the specifics of the deal: Just four days after each episode airs on CBS, they will pop up on Amazon Prime Instant Video. The episodes will be available to stream on CBS.com, but only for the first three days after airing.

Under the Dome is based on a 2009 Stephen Kings novel of the same name that’s about a small New England town that is suddenly cut off from the rest of the world by an giant, transparent dome. It’s being produced by Steve Spielberg’s Amblin Television and will premiere on CBS on June 24th.

“With creative forces of Stephen King and Steven Spielberg’s Amblin Television behind Under the Dome, we think our customers will love this new show and we’re excited to be able to offer this highly-anticipated series at no additional cost to Prime members,” said Brad Beale, Director of Digital Video Content Acquisition for Amazon. “Adding a current season major network TV series like Under the Dome to the Prime Instant Video library so shortly after its live airing enables us to increase our exclusive selection of great TV shows and give customers access how, when and where they want to watch it.”

Last week, Amazon made another big play when they stole Downton Abbey away from Netflix and Hulu. Per that deal, Prime Instant Video will be the only subscription-based streaming service where viewers can watch episodes of Downton Abbey – past, present, and future (starting some time this year).
