My kids never really got into watching sports like baseball, basketball, football, etc. When I was their age (teens to eary 20s) my life revolved around watching all manner of sports whether it was live or on TV, but my kids would probably rather have their toenails removed than to be forced to sit through a couple of hours of game watching.
Actually I need to revise that last sentence; at least one of my kids LOVES watching video of other people playing the newest "sport" - eSports aka video games. According to this article he's not alone:
In October, some 15 million people tuned in to watch Major League Baseball’s World Series in the United States. But that’s nothing compared to the other big sporting tournament that took place around the same time: In late September and early October, 32 million people watched the League of Legends Season 3 World Championship, according to a new report (pdf) from SuperData, a games research company.
Indeed, the finals of the competitive tournament for players of the online multiplayer game resembled a major physical-world sporting event, with the 18,000 tickets to watch it live at the Staples Center in Los Angeles selling out in one hour. On the day, the capacity crowd gathered to watch teams do battle against each other as they spawned minions and unlocked glyphs.
I really am so0000 last-century.
