Here’s the latest sign of Amazon’s eagerness to make subscription streaming services a big part of its retail offerings. It just agreed to offer Amazon Prime customers the opportunity to use their accounts to buy Seeso, NBCUniversal Digital Enterprises’ $3.99 a month ad-free comedy service.

The video provider will be available via Amazon “this Spring,” the companies say. Subscribers will be able to access Seeso’s library online and via the Amazon Video app for TVs, streaming media players, and mobile devices.

As you’d expect, it will work with Amazon’s Fire TV, Fire TV Stick, and Fire tablets.

NBCU launched Seeso in January, offering subscriptions directly.

Amazon Video Channels’ Director of Content Acquisition Rich Au says that “the way people watch TV is changing, and customers want easier access to their favorite shows, regardless of device or subscription.”

NBCU SVP Ben McLean touts Seeso as “the first standalone comedy offering” with “the best premium content – Original Series, stand-up specials and library video—across every screen.”

Subscribers can watch full-length episodes of The Tonight Show Starring Jimmy Fallon and Late Night with Seth Meyers the day after they air, as well as “40 plus years of Saturday Night Live.”

Other subscription services available on Amazon include Showtime, Starz, the Lifetime Movie Club, AMC’s Shudder and SundanceNow.
