Actually, it is well documented how Joe Benigno got his job. He had been a frequent caller to WFAN (Joe from Saddle River) and had a bit of a cult following. WFAN ran a contest, offering a guest-host spot as the prize. Benigno won. That added to his cult status, and he was eventually offered the WFAN overnight gig.
I can see how he might appeal to the overnight audience. What is less clear is how he has had continued appeal to the broader audience.
