Jimmy Fallon, host of "The Tonight Show," canceled a Thursday appearance on a Fast Company panel about his new NBC reality series, "On Brand."

NBC is putting new emphasis on late night host Jimmy Fallon's interest in advertising and marketing and creating ads for sponsors

Jimmy Fallon and an audience of 3,000 got a big dose of Motor City magic Sunday afternoon, when NBC’s “The Tonight Show” did a live taping in Detroit.

NBC brings "The Tonight Show" to the Detroit Opera House and the Detroit Lions' football field with Roary, the mascot.

Cardi B's not the only famous marketing expert: Jimmy Fallon assumes the role of marketing agency CEO in his new show, On Brand with Jimmy Fallon, in which 10 competitors angle to win ad campaigns with major brands like Dunkin' and Southwest Airlines, culminating in a prize of $100,000.

Jimmy Fallon gave Travis Kelce his advice for planning a wedding, weeks after the Kansas City Chiefs tight end proposed to pop icon Taylor Swift. Fallon, the guest on the Sept. 17 episode of Kelce's "New Heights" podcast, which he co-hosts with his older brother, Jason Kelce, asked if the NFL star and Swift had started wedding planning yet.

This week, Martin, Steve, and their Only Murders in the Building costar Selena Gomez appeared on Jimmy’s show for a wide-ranging chat — and things got off to an awkward (but hilarious) start when the comedic duo immediately delivered a politically-charged roast.

Fallon gave shout-outs to She Wolf, Buddy's Pizza and Miller's Bar in Dearborn, spots he had eaten at over the last few days while in town for the taping. He also gave a shout-out to Motown legend Martha Reeves, who was watching on from the box seats in the mezzanine, among the 3,000 attendees at the taping.
