Microsoft Corp is closing down Mixer, its live streaming service for games, and shifting users to Facebook Gaming, the technology giant’s Xbox division said on Monday.Starting on July 22, all Mixer sites and applications will redirect users to Facebook Inc’s gaming app, Xbox said in a blog post.Microsoft bought Mixer in 2016, hoping to rope in millions of paying subscribers looking to watch live streams of their favorite gamers competing in e-sports or playing popular video games such as Call of Duty and Grand Theft Auto.However, despite online streaming viewership booming under coronavirus lockdowns, Mixer has struggled to leave the shadow of market leader Twitch, owned by Amazon.com Inc.
