Most sports involve the viewer following a ball (eg rugby, pool, golf), some centre of action (eg boxing, synchro swimming!, ice skating, freestyle snowboaring) or somebody trying to go faster/higher etc. than the others (racing etc)
In paintball the centre of action is everywhere. Paintbal on tv looks crap (eg the Bravo thing), at least in a stadium you can see the whole field, but you can miss action if you are looking at the wrong area of the field at the wrong time. Fitting cameras to each player and having cameras cover all the field then some serious editing might provide some interesting tv, but I doubt it, with paintball the adrenaline rush is personal, at least with say watching skydiving you can imagine yourself falling and get some adrenanline, but sitting at home watching some guy shoot paint at another may not do it. How about football you say ? Theres a lot more to football than a few guys kicking a ball around, its about belonging to a "tribe" and wanting your tribe to win.
There are currently hundreds of sports and activities, all wanting to be in the mainstream, sports like sky diving are ocassionaly on tv as its seen to be slighly crazy and dangerous, surfing as its a part fashion cool i.e might assocation with it might make you more attractive to women. To most people. paintball is a fun day out and on hearing about tournaments its basically another activity. Its also expensive compared to say mainstream sport (i.e tourney marker + equipment + tourney fees + paint fees). Ok mountain bikes etc. can be expensive, but once you have bought it theres only maintenance costs to worry about.
I dont think paintball will ever become a mass or even minor spectator sport. The excitement is all in the players head.
I love playing paintball. Play it and love it. If you want people to watch you, take up surfing or perhaps acting. Otherwise, put on your goggles and game on!
