YouTube stars, Boyce Avenue

Corden just became the first late-night talk show host to film an entire episode inside YouTube Space L.A., a 41,000-sq.-ft. facility equipped with green screens, cameras and sound gear – basically, a YouTuber's paradise. Joining him for the big occasion were a number of YouTube stars, including Jenna Marbles, Tyler Oakley, Kandee Johnson, The Slow Mo Guys and The Creators of "Epic Rap Battles of History." The episode – in which Corden interviews said YouTubers, as well as engages them in a round of the Late Late Show's signature hijinks – is part of the celebration around YouTube's 10-year anniversary.
