After Leno officially retired from “The Tonight Show” in 2014, he began hosting “Jay Leno’s Garage,” an Emmy-winning web series about cars — inspired by his side passion — that landed a prime-time spot on CNBC in 2015. He said in a news release at the time that the show would be “about anything that rolls, explodes and makes noise,” and would “highlight the passion and the stories behind the men and women who made the automobile the greatest invention of the 20th century.”
