Actually, 700, Jerry's resumé is even more impressive than that.
In the late 1960's, while still a student at Temple U., he started doing news in the evening on "Famous 56" WFIL/Phila., when it was one of the most important Top 40 stations in the country (having just knocked off Storer's WIBG, or "Wibbage"). So he learned early on what it was like to be part of a ratings monster in a major market.
A few years later, he got out of broadcasting and founded Inside Radio. In his latter days with IR, he was a constant critic of the effects on consolidation, made a lot of enenmies, and had some high profile lawsuits.
Of course, IR now belongs to Clear Channel, and is little more than a cheerleader for the industry, which sees no need for a conscience -- or a scold, if you prefer -- like Jerry.
There, in broad strokes, is his earlier career. He was in radio when radio was really radio, not what CC and the other Wall Street-driven vulture corporations have made it today.
