The story of Counter-Strike esports [video]
I posted a video of Peak Esports 2019 yesterday, here's a video that shows how esports 1.0 evolved from 1999 to 2012.
The video features young handsome versions of HeatoN, Pott1, elemeNt, XeqtR, Rambo, moto, zonic, SirScoots, Thorin, n0thing and many others. It shows the rise of Counter-Strike esports, from conference rooms to convention centers.
For contrast, this is what Counter-Strike esports looked like 20ish years later.
