Former syndicated radio personality Tom Leykis has been podcasting for awhile now (ever since he lost his last radio gig), and he has come to the same conclusion that Steve Dahl did--there's no need to go back to radio.
"Not only is it satisfying to state there our show is a success by the number of people listening, but we are also making a profit. I want everyone to know that I'm not rooting for the demise of radio. On the contrary, most of my friends still work in radio. It's just clear from the sheer tonnage of listeners we now have that there is no need to return to radio."
You know what? I believe him (and Steve).
