Joe Rogan gets 400-500 million views across major platforms every month.
He is the biggest voice in US Media and dwarfs all mainstream media prime-time hosts...combined.
People here might not watch him, but he is a trendsetter for popular culture of the under 45 age demographic (highly sought after by advertisers across the board)
The most famous/popular comedian after Dave Chapelle. His audience is not going anywhere regardless of whatever attacks the mainstream media launches against him, and this hoopla has only made him bigger.
