According to a new “State of the Stream” report from live-streaming platform StreamElements, gaming fans watched nearly 9.4 billion hours of content on Twitch last year, a 25 percent growth rate over 2017. While YouTube Gaming’s live content viewing totaled 2.3 billion hours (or about a quarter of Twitch’s hours), YouTube’s year-to-year growth rate was an impressive 104 percent. Microsoft’s live-streaming Mixer, which launched in 2016, had almost 168 million hours watched last year, which was an increase of 179 percent over 2017.

“Fortnite” holds the top spot of “the 10 most viewed streamed games of 2018,” but the game’s “viewership is on a downward trend,” reports VentureBeat.

“It peaked during the second quarter of 2018 with just under 400 million hours. That was down 15 percent to 340 million during the fourth quarter. But it still has a commanding lead as streaming’s most popular game.”

“Fortnite” battle royale competitor “PlayerUnknown’s Battlegrounds” (“PUBG”) fell from #2 in 2017 to #5 in 2018. The other titles listed in the top 10 include “League of Legends,” IRL/Just Chatting, “Dota 2,” “Counter Strike: Global Offensive,” “Hearthstone,” “Overwatch,” “World of Warcraft” and “Grand Theft Auto V.”
