Conan O'Brien's new TBS talk show was a hit with young viewers Monday night, delivering an audience with a projected median age of just 30. Conan - which featured guests Seth Rogen, Lea Michele and Jack White - was watched by 2,451,000 adults 18-34; 3,285,000 adults 18-49; and 4,155,000 viewers.

O'Brien has a strong following among younger viewers, and social media has proven to be a key way for him to connect with his fans. "Conan's audience has been very vocal online, and he clearly made a smooth transition from Twitter to TBS," said Steve Koonin, president of Turner Entertainment Networks. "Conan delivered an extraordinary audience and stands out as the youngest late-night talk show on television."

Tonight, Conan will welcome guests Tom Hanks, Jack McBrayer and Soundgarden. Upcoming guests include Jon Hamm, Fistful of Mercy and Charlyne Yi on Wednesday; and Michael Cera, Julie Bowen and Jon Dore on Thursday.

Conan originates from Stage 15 at Warner Bros. Studios and is produced by Conaco LLC. Jeff Ross is the executive producer.
