Most major eSports events/tournaments are organized by game developers such as Steam that offer live streams OTA (over the air). The streams are usually available over Twitch or YouTube. Twitch itself grew into a ‘lair’ for gamers in the past couple of years. The platform is pretty popular around the world and is one of the best spots where you can watch eSports tournaments. All for free, of course. The only thing you need to do is register at Twitch or YouTube to watch the streams. Additionally, some online eSports betting sites might offer live streams of major eSports events where you get to watch the games live free of charge.
