Tomorrow, Comcast will launch an early preview of the premium tier of Peacock, NBCUniversal’s new ad-supported subscription streaming service, included at no additional cost for Xfinity X1 and Flex customers across the US.

The early preview will be followed by the national launch on July 15, which includes a free tier featuring more than 7,500 hours of movies and shows that will be accessible to all across mobile, web and popular connected-TV platforms. At this time, Peacock Premium will also be available for $4.99 per month on all popular connected devices, as well as an ad-free tier for an additional $5.00 per month.

All Peacock programming is supported by advertising featuring approximately five minutes of commercials or less per hour and launch sponsors.

Rolling out over the next few weeks, X1 and Flex customers can start streaming more and scrolling less by simply saying “Peacock” into the Xfinity Voice Remote.

Xfinity Flex is a personalized, 4K streaming device that is included free with Xfinity Internet and offers free movies and shows. Flex customers can find Peacock movies and shows in the “New This Week” and “Free to Me” rows, as well as explore content via a “Trending Now on Peacock” row among all of their other streaming favorites in one place.

X1 customers can also browse Peacock programming editorially integrated throughout the X1 guide, right alongside all of the live TV and on-demand shows and movies included with their Xfinity TV subscription, and other streaming services available on X1.

The service was meant to have a mix of originals, classic shows and movies, and current NBC programming like its late-night shows and “Law & Order: SVU.” Original shows are key to hooking consumers inundated with new streaming services, but the coronavirus pandemic has largely shut down Hollywood production.

Peacock was also supposed to get a big push from the Olympics this summer, but the quadrennial games have been postponed until 2021.

Peacock now expects to have “dozens” of premieres of originals in 2021, said Matt Strauss, the company's chairman.
