NBCUniversal has unveiled its own streaming service. Peacock, a free premium ad-supported streaming service, will offer subscription tiers with more than 600 movies and 400 series. Live and on-demand content across news, sports, late night and reality will also be available.

The streaming service’s first set of launch sponsors include State Farm, Target, Unilever and Eli Lilly and Company.

“This is a very exciting time for our company, as we chart the future of entertainment,” says Steve Burke, chairman, NBCUniversal. “We have one of the most enviable collections of media brands and the strongest ad sales track record in the business. Capitalizing on these key strengths, we are taking a unique approach to streaming that brings value to customers, advertisers and shareholders.”

The Peacock streaming service offers two tiers, free and premium. The free version provides fans with more than 7,500 hours of programming including the Olympics and Spanish-language content. In addition, it will offer select episodes of Peacock originals and curated genre channels like “Olympic Profiles,” “Family Movie Night” and “SNL Vault.”

The premium version will come at no additional cost to Comcast and Cox subscribers and will come with full seasons of Peacock originals, next day access to current seasons of broadcast series, early access to late night talk shows and additional sports. The premium option will total more than 15,000 hours of content. For non-bundled customers, it will be available for $4.99 per month on all popular connected web and mobile devices. The ad-free experience will cost $9.99 per month.

Peacock will launch April 15 to Comcast’s Xfinity X1 and Flex customers. It will debut nationally on July 15.
