There are not many trad shows because the budgets of trad companies don't compare. Bows and gadgets that age and evolve quickly are great for creating large advertising budgets.
I know a guy that had produced and helped produce shows on the big outdoor channels. I couldn't believe what it cost for a shows slot. It was well over a half a million dollars for thirteen episodes. The show has to pay for their slot and then (hopefully before) line up sponsors to cover the cost of placement, producing the show, and hopefully make a profit in the end. He said there is so much competition with hunters buying prosumer comcorders and willing to work for nothing that it is an extremely difficult market unless you happen to be one of the well respected and long running shows.
I was shocked when I got a quote for a full page color ad in some of the moderately circulated (100,000 copies) hunting magazine, not the biggest ones remember, $30,000+ for a single month.
One of the great things about trad is that we get to purchase bows and gear that will last decades. Compound bows and equipment are like computers, you pay a lot and don't expect to have it more than a few years. Completely different markets and there is a lot more money that flows into the latter.
