Beck has many irons in the fire, so to speak. His books are bestsellers on Amazon in a matter of days after their release. His shows (radio and TV...Rush has radio, O’Reilly has tv)...only Beck has both. He has a magazine, and then he does live shows, not to mention money generated by his website access. The man is an entrepreneur in the truest sense of the word.
Slight correction...Hannity has both TV and radio too.
