Long-time UFC analyst Joe Rogan began his very own Joe Rogan Experience podcast with fellow comedian Brian Redban in 2009. At the time, the two would simply riff on camera, talking about anything and everything under the sun.

11 years later, Rogan still continues with his own brand of conversational interviews. But the personalities who’ve sat across him have greatly varied, from scientists and politicians to musicians and A-list celebrities.

The former Fear Factor host has indeed come a long way, as he recently made the top of the list of Forbes’ highest-earning podcasters with a $30 million revenue. Apple also named “JRE” as the number one podcast in the world with 190 million downloads per month.

Here is the top five list (H/T MMA Mania):

Joe Rogan: “The Joe Rogan Experience” — $30 million Karen Kilgariff and Georgia Hardstark: “My Favorite Murder” — $15 million Dave Ramsey: “The Dave Ramsey Show” — $10 million Dax Shephard: “Armchair Expert” — $9 million Bill Simmons: “The Bill Simmons Show” — $7 million

As a mixed martial arts commentator, Rogan has since dedicated a show for when he sits down with fighters and personalities in the game. Aptly named the JRE MMA Show, some of the previous guests include Ben Askren, Frankie Edgar, Kamaru Usman, John Danaher, Jorge Masvidal, Ronda Rousey, and UFC president Dana White, among many others.
