The service will launch in the spring at an unspecified date in "the largest United States markets", according to a YouTube statement.
On Tuesday, the Google subsidiary introduced YouTube TV with about 40 networks onboard to stream their live broadcasts and cable feeds to its subscribers.
YouTube executives said they aimed to make the YouTube TV app easy to use across mobile devices, desktop computers or an Internet-connected televisions.
When you find something you want to watch, you can either pull up a full-screen viewer within the app, or cast the video to your Chromecast-compatible TV.
As for what that content is, YouTube appears to have pushed hard against the major TV networks' arcane distribution rules to offer as much local and national broadcast as possible. It has launched stars and given rise to the influencer and creator movement while also being a hub for new opportunities through its YouTube Red subscription service.
McIlroy battles belly bug to contend in Mexico
As for his golf? McIlroy could return to the top of the World Golf Rankings with victory at the WGC event in Mexico this week. With a 368-yard drive, a 256-yard 4-iron and a 28-foot putt, McIlroy bounced off the green with an eagle on his scorecard.
And some significant TV programmers are not part of YouTube TV.
What YouTube is really pushing, though, is the notion that while it may have the same programming as its competitors, it will have a better service. The service will be able to record unlimited shows at once with its cloud-based DVR - with no storage limits. In practice, it looks a lot like the streaming services that have entered the market before it, but with a healthy dose of trademark Google simplicity and powerful artificial intelligence behind the scenes.
"Reliability and scalability" - a not-veiled reminder that other digital TV services have had technical struggles when they first launched.
It will cost $35 per month and include a virtual DVR service. Viacom, whose networks include MTV and Nickelodeon, and Time Warner, parent of TNT and CNN, are both absent. Local news programming from network affiliates will also be included, according to Robert Kyncl, YouTube's chief business officer. And none of the streaming TV services will let you watch football on your phone, because those rights, for now, are exclusive to Verizon.
