% of Esports Turnover: 2%

Call of Duty at Esports World Cup: 2.68 million hours viewed

Call of Duty’s most recent game is Black Ops 6 but a lot of the tournaments in 2024 were still running on the older title. There’s no denying that Activision has continued to crank out new Call of Duty titles, likely because of how popular the game has continued to be. There are around 100K concurrent players every month as of fall 2024. When it comes to esports, CoD has a lot of growing to do to keep up with the heavy hitters, but it’s continued to prove itself thanks to the Call of Duty League. 

Other big esports include Overwatch 2, Apex Legends, PUBG, and Rocket League. Overwatch 2 has been wavering, however, after the fall of the Overwatch League and Marvel Rivals grabbing the attention of players during this past month.
