I've been doing the Progressive IMS show tour for many years now ( I don't work for the company that puts on the tour, but with a vendor). The shows have been getting smaller and smaller over the years. I was not at the Long Beach or Dallas shows but my co worker that was said that they were good shows this year. The Show in NYC was ok, but a lot slower and smaller than the last few years. The Cleveland show is up next. It is a top 3 show as far as attendance (NYC #1, Chicago #2) but the amount of vendors has gone down. I don't think i ever seen a seat vendors at any of the shows. I think a big hurtle that the aftermarket manufactures look at when they think about this show is the expense. Show booths are not cheap. I know what the show costs for the company I work for and what the budget to per show is to have the booth maned. It can be a big gamble if the company is not getting a good return on the investment. Yes, other factors do apply to doing any show(staffing availability, conflict with other shows, ETC). There are a few OEM manufactures that didn't have booths at all the show stops last year and i'm sure a few will be missing from the smaller shows again this year. Yes, the industry is down. It has been down for years now. Hopefully it gets better soon.
