If you know a man who listens to podcasts, he will almost certainly have listened to Joe Rogan.
According to Apple podcasts, The Joe Rogan Experience is the biggest podcast in the world. His podcast is downloaded over 200 million times a month. For context, that's double the amount of people who watch the Super Bowl every year — the most popular sporting event in the world.
However, as Rogan has increasingly moved towards right-leaning interview guests and shared his own support for right wing candidate Donald Trump, the podcast has both drawn controversy and attracted people aligned with these views.
Rogan launched his podcast back in 2009 and has since released 2,300 episodes, giving him one of the longest back catalogues of any show.
Rogan spends more time in men's ears than almost anyone else, and yet the average person knows very little about him.
Here's what we know about the life of Joe Rogan.
"Violent flashes of domestic violence."
Rogan's mother was a teenager, some speculate around 14 years old, when she gave birth to him in 1967. He grew up in New Jersey, and has not had any contact with his father since he was seven.
Speaking to Rolling Stone in 2015, Rogan said: "All I remember of my dad are these brief, violent flashes of domestic violence. But I don’t want to complain about my childhood.
"Nothing bad ever really happened to me. It was just confusing, you know? He was just a very violent, scary guy. After the split, we moved to San Francisco and that was it. Never heard from him again... I don't hate the guy."
