There are over 5 minutes of ads at the start of every Joe Rogan podcast, as well as others throughout. One analyst suggests Rogan has acheived a net worth over $1bn based on the number of downloads & estimated advertising revenue based on those figures: http://www.insideradio.com/podcastnewsdaily/joe-rogan-podcas...
As written above, I know about the intro ads, but they are only being done in the podcast version. The youtube versions of the same talkshows dont have a single bit of advertisment for me, neither at the beginning nor in the middle.
