When viewing through X1, users who are signed into their YouTube accounts will see their personalized settings and subscriptions. The service is also tied into Comcast's voice remote so that people can search or simply say ""Watch Carpool Karaoke on YouTube," and then it will start playing. In the VOD section, there will also be themed categories covering eSports, music, entertainment and local news.

Even though YouTube (like Netflix) has been available throughout living room devices, spreading to Comcast cable boxes is a reflection of the public's changing video habits. A report released this morning by Limelight showed that US viewers are averaging over seven hours a week watching online videos, and for Comcast, keeping them within its ecosystem may be a better option than sending them to another interface it doesn't control. As executive VP Matt Strauss puts it, "By adding billions of YouTube videos to our video platform, we are taking our role as the aggregator of aggregators to a new level and reaffirming that X1 is the best place to easily discover and access all types of entertainment with the sound of your voice."
