Popular compared to what? I beilive its more active chess-players in the world than boxers or hockey-players in that manner.
So in a list its probably around top 10 sports/games where there is a serious competition.
Why its seldom shown on TV its becouse the format isn't that good for production.
I don't know how true that is, that chess is more popular than boxing or hockey. But I can say that chess is a unique sport, if that's what you'd classify it as, because it's not seasonal. You can play all year round. Anytime anywhere. :)
To be perfectly honest, this is coming from a non background and non playing chess person, till recently.
I think chess is extremely popular, I'd say it would easily beat any game out there when it comes to amount of people who play (popularity) and when people play chess it turns into a (game of life), lifetime game. What other game has such continued support?
Chess has stood the test of time, chess is not just a fad, no other game could ensure it's mass popularity throughout the test of time, and if 1500 years doesn't prove this as fact, then you Sir/Madam will never be one to see the forest for the trees.
Chess is and always will be the #1 game people play!
