Dont forget where esports was 5 years ago, Volvo and Riot did incredible job pushing it forward. TV, however, each and every year is less and less attractive, but that doesnt mean broadcasting channels arent interested in it (Sweden, Korea, China, recently Germany with ESL One). Also the main thing is old fart's mentality; new generation will see esports in a different light, as most of them are/were gamers just like us. Its still very risky to be a pro player today, but it will change. On the other hand, conventional sports have this advantage of being "immortal", while games die within a couple of years; ARTS games (DotA/Dota 2, as of right now) and CS/CS:GO, though, have proven having long lives and keep getting more and more popular, but without a good developer with vision and will to constantly improve, doing things right, games will sadly keep dying and get replaced by new titles.
