I've listened to Cornette's Drive Thru for a while, but have expanded into two other podcasts that I think are extremely underrated - Tony Schiavone's and JR's. I'll probably check out Bischoff's as well soon. Schiavone and JR both have the same co host, Conrad Thompson, who I think does an excellent job with his own knowledge and great questions, which stimulate good discussion. Even if you did not follow the business back then, Conrad paints a great verbal picture of where the companies, talents, business, and dynamics were at the particular time in question, and uses Meltzer's WON as a loose background.
It's good stuff.
