Last year Comcast plugged Netflix streaming into the X1 setup and starting today it's rolling out YouTube access nationwide. Just as the company announced earlier this year, the service's videos will be available via the YouTube app, or in Comcast's video on-demand section. According to YouTube exec Robert Kyncl, "The living room is YouTube's fastest growing platform. We are excited to supercharge our distribution there and bring Xfinity X1 users a seamless way to consume all of the content they love. Voice is a key enabler to discovery and we are looking forward to bringing it to Xfinity X1 users."
