In this commentary, NPR’s v.p. of programming responds to Ira Glass’s suggestion that stations not devote prime weekend airtime to Car Talk reruns after the Magliozzi brothers retire this fall. Like Ira, I’m really excited about all the innovation in public radio today. Each of these new programs will need several things if they are to grow and prosper: an intellectual spark, real talent giving them a unique, authentic voice, money, smart plans for development, and stations willing to take a small risk. There is one other critical thing they need to grow and prosper: Car Talk. Airing Car Talk on Saturday mornings doesn’t stand in the way of innovation.
