Research looking at Twitch viewership has found that 65 percent of Twitch’s hourly viewing figure is split between just four games.
Those games are, in order or popularity, League of Legends, Counter Strike: Global Offensive, Dota 2, and Hearthstone.
Data presented by French video game analytics company, Gamoloco, shows those four titles have held their positions at the top since 2014, and, as of April 2015, represented 79.8 percent of the total viewing time achieved by Twitch’s ten most popular games.
"Since September 2014, it's always been the same four (games)," said Nicolas Cerrato, founder of French platform Gamoloco.
"The biggest variation consisted in a switch between Dota and Hearthstone, in late 2015, when an important Hearthstone tournament took place."
Looking at each game's viewership in terms of hours watched per month, League of Legends' viewing figure grew to 88 million hours watched in April 2016 from 80 million in April 2015. Counter Strike’s viewership also rose to 73 million from 39 million over the same period.
In the same time, Dota 2 racked up 43 million hours watched, compared to 31 million in 2015, while Hearthstone’s year-over-year viewership increased to 41 million from 31 million.
