(Reuters) – Comcast-owned NBCUniversal entered a crowded streaming market today by launching its Peacock streaming service nationally, offering 20,000 hours of content, including NBC shows such as “30 Rock,” “Cheers” and “Saturday Night Live.”

The service, which became available to some Comcast subscribers in April, is the media giant’s effort to offset declines in Comcast’s cable TV business – while finding a new way to monetize NBC and Universal content and maintain demand for the company’s broadband business, which powers streaming services.

Peacock will include a mix of NBC series, sports, news and original shows – such as the dystopian drama “Brave New World” and documentary “In Deep with Ryan Lochte” – as well as content it licenses from ViacomCBS and other networks and studios.

The service will also be available on Sony’s PlayStation 4 gaming console from July 20, Peacock said on Tuesday.

Unlike the majority of its streaming rivals, Peacock is offering a free, ad-supported version, which will include 13,000 hours of programming. NBCUniversal hopes to lure advertisers through the vast amounts of data it can use to target commercials based on viewers’ interests, including data from Comcast’s cable TV set-top boxes.

Peacock also has two paid options: a $4.99 per month service with commercials and 20,000 hours of programming; and an ad-free version costing $9.99 per month.

NBCUniversal missed the opportunity to market Peacock during its broadcast of the Tokyo Summer Olympics, which were postponed due to the coronavirus outbreak. And as the last entry to the streaming war, Peacock will be competing for streaming dollars with services such as Netflix, Walt Disney-owned Disney+ and Amazon.com’s Amazon Prime Video.

But Peacock’s free option could be a draw for viewers who have already maxed out their monthly entertainment budgets, at a time when U.S. viewers stuck at home are hungry for more content.
