Jay Leno's new CNBC show launching in 2015

Jay Leno is officially returning to nightly television.

The former "Tonight Show" host's new venture, tentatively titled, "Jay Leno's Garage," and based on his Emmy Award-winning Web series, will premiere on CNBC in 2015, the network announced Wednesday. The precise debut date and frequency of airing are yet to be determined, the network said. Word of his CNBC gig spread earlier this month.

The hour-long show will be a forum for Leno to share his passion for "all things automotive," the network said, "including best investments, valuations and the inner workings of the car collector's market."

Leno commented, "This show will be about anything that rolls, explodes and makes noise. We hope to highlight the passion and the stories behind the men and women who made the automobile the greatest invention of the 20th century."

"Jay will add tremendous star power and exceptional content to CNBC's prime time at the perfect time," said network President Mark Hoffman. "We're really excited Jay will continue his storied career with the NBC family and with us at CNBC."

The 64-year-old Leno, well-known for his interest in cars and his vast car collection, hosted a one-hour special for CNBC in August. "Jay Leno's Garage: The Ultimate Car Week" marked his first return to hosting since he vacated NBC's "The Tonight Show" last February.
