I love history--of all kinds. I especially appreciate the rich history of radio. Gee, what a surprise! There's a new book out by radio historian Bob Shannon called Turn It Up! American Radio Tales 1946-1996 that looks to be a fun read.
In addition to the book, there's going to be a series of free audio excerpts (podcasts) available which are posted here. The first of the series was just posted today and it's Fred Winston's sneak preview of the Dick Biondi Story.
We can't expect our medium's history to provide the answers to the myriad of issues we face today; but we can certainly look back and enjoy what I think most of us would agree was pretty damn good.
