Hello, friends. After more than 30 years in television and radio news I'm embarking on a career in small-market radio sales. My training begins this week. As a supplement to that training, I'd like to read the radio sales books which you sales vets consider the best of the lot. The two recently-published books most prominently featured in an amazon.com search are "Selling Air" by Bob Diamond and "Successful Local Broadcast Sales" by Paul Weyland. Your thoughts on these and other books are most appreciated by yours truly. Thanks in advance.
