Twitter has already proven to be a popular tool for talking about TV shows, and soon, the platform will become a way to watch shows, too.

NBCUniversal and Comcast announced Wednesday that they have entered into a partnership with Twitter that will let "millions" of Xfinity TV customers view TV shows and movies via tweets through a new feature called See It.

"See It will be integrated into a show’s tweet, so that with the click of a button, I can change the channel on my TV right away, record it or even watch on my mobile device," Sam Schwartz, Comcast's chief business development officer, said in a blog post.

The See It button, which will start showing up in tweets later this year, will let customers tune into shows online or from set top boxes, set their DVRs and even buy tickets through Fandango. NBCUniversal's networks like CNBC, SyFy, NBC and others will have access to the feature, for shows including The Voice, Today Show, Access Hollywood and many more.

While subscribers will have access to more options, non-subscribers will also be able to use the See It button to see shows they might be able to access through other apps from places like Hulu or ABC.

Here's a mockup of how the service will work when it launches:

"Twitter is where television viewers come to talk about what they’re watching on TV when they’re watching it," Dick Costolo, Twitter's CEO, said in a statement. "Millions of users are exposed to the live conversation that unfolds on Twitter while a show is on the air and now, with See It,they’ll be able to tune in directly from a Tweet."

Twitter has been looking to boost its TV network partnerships in recent months to get a piece of the lucrative TV ad business as it gears up to become a public company. Earlier this week, Nielsen announced a brand new Twitter TV ratings system.

Comcast is focused on the Twitter partnership for now, but a rep for the company told Mashable that it is currently in talks to roll out the See It button on other entertainment websites like IMDB and Flixster.
