Actually... I didn't realize how much NAMM charged the vendors.
If they are charging $5000 for a little cubby then I'm assuming a proper area is going to be quite a bit more... and that would not include all the other expenses incurred.
So to have a proper presence having to spend 1/4 - 1/2 the yearly salary of a full time employee (who could be coding instead) just to get on the floor is pretty obnoxious for a smallish company to pay. When worked booths at such shows we'd drop maybe a few hundred bucks for the weekend AND we made it back and more because we were actually selling stuff from the booth (as well as promoting other events and the shop).
Even that wasn't totally worth it sometimes.
So who runs NAMM? This seems like someone(s) is gouging for extra profit instead of it being the industry just getting together to co-mingle, promote and learn (with some sort of pro organizer and the convention center making a reasonable profit for their part but not deterring actual industry entities from participating).
The vendors are the damned "pull". If they get excluded due to exorbitant fees then it deteriorates the quality of the event.
Then you are only left with the McDonald's and Pizza Huts of the industry and everyone already knows about them and what they serve up.
