Knowing the eSport
Before 2019 this eSport was played on Playstation, whereas now it is all played on PC, Call of Duty was one of the only eSports of its size that was on console before the move over. When Call of Duty eSports was on console its was ran by a company called Major League Gaming(MLG) which they created the CWL (COD World League), But when Activision acquired MLG in 2016 they wanted to make eSports mainstream. Activision held out until 2019 where they created the Call of Duty league (CDL) which had a $25 Million buy in for the organistions to have a team in the league.
Before the league you all you had to buy to play the Major Touraments was a team pass, which was normally around $200 per team, So as you can imagine there were many young organizations that couldnt afford the $25 million buy in. The league also meant that teams/organizations had to rename that did buy a league spot as the league were based aroiund locations. So an example of this is the team called EnvyUs had bought a league spot and named their team the Dallas Empire and Faze Clan one of the leading organizations bought spot and is called Atlanta Faze
