YouTube is looking into paid subscriptions, potentially making specific cable channels available, Salar Kamangar, Google senior vice president, YouTube and video, told Reuters.

Some cable channels with smaller audiences will be available online on an "a la carte" basis, Kamangar said at the Reuters Media and Technology Summit on Thursday, according to Reuters. YouTube is also looking into making some of the original video programs featured on YouTube "channels" available for a fee.

YouTube streams more than 4 billion online videos every day, making it the world's biggest online video website, according to the article. Currently, the company makes money by selling advertising including pre-roll video ads and sponsorships for particular parts of the site. Google doesn't break out financial results for the website, however.

"We don't have anything to announce now. It is something that's really important to a lot of our top existing content creators as well as ones that aren't on YouTube today, so we're taking (it) very seriously and we're thinking about it very carefully," Kamangar told Reuters.
