Automakers used to exhibit at all the major auto shows around the world. Now, they're skipping a lot of shows and being pretty picky about which ones they go to. Why is this happening? And how can auto shows re-invent themselves to bring them back? Three panelists with extensive auto show experience share their knowledge of where these shows have been and where they're going. On this show: Rod Alberts, executive director of the Detroit Auto Dealers Association, John McElroy, Autoline.tv, Steve Bruyn with Foresight Research and Jason Vines, communications consultant and author.
