Ninja just defected from Amazon's Twitch to Microsoft's Mixer, bringing along a gargantuan audience and a pile of influence along with it. The flip is a big win for Microsoft's fledgling streaming platform, which has been growing steadily since it joined the Xbox family.

Ninja's recruitment should silence the naysayers, though, and prove that Microsoft is serious about giving Mixer a real chance at hitting the big leagues.

How big is live streaming right now?

The biggest players in video game online content right now are, by far, Amazon and Google, two of Microsoft's biggest rivals. The combined forces of YouTube and Twitch utterly dominate Mixer, with Twitch by far the leader in live-streamed content. According to a report from Streamlabs, Twitch enjoyed almost 3 billion viewing hours in Q2 of 2019, while YouTube scraped over 700 million. Mixer trails in a distant third, with just 100 million.

Viewing hours on Mixer have increased roughly 357% year over year, hitting 37 million viewing hours in Q2 2018, and almost 120 million in Q2 of 2019. Beyond dedicated video game streaming, platforms like Facebook, Instagram, Twitter, and many others around the world are also competing for eyeballs in the space, although in different ways. Microsoft's leveraging of its Xbox platform puts it in a unique position in terms of video game live streams, however, since it has the ability to bake Mixer tech directly into both Windows 10 PC and Xbox consoles. Why Ninja, and why now?

Ninja is one of the internet's biggest video gaming personalities. Riding at the very peak of the Fortnite hype wave, Ninja has found his way onto TIME Magazine's top 100 most influential people, courting headlines from mainstream outlets all around the world. The news that he was ditching Twitch has immediately hit mainstream news thanks to Ninja's celebrity status, including TMZ and Business Insider. But why now?

Besides a boatload of cash and Ninja's obviously massive influence, there's some evidence to suggest the video game streaming market might be nearing its peak. At least for the moment, the boom driven largely by Fortnite seems to be stalling, with Twitch experiencing its first-ever decline in viewership earlier this year. Considering Ninja is known primarily for streaming Fortnite, signing up to a comfortable deal with Microsoft could be his way of bailing out before the wave truly crashes. If streaming is indeed nearing its peak (and I really doubt that it is) picking apart Twitch's audience sooner, rather than later seems like a good bet. But if all of this indeed true, how does Microsoft benefit in the long-term? In Ninja's press release on the signing, he was keen to mention his gaming roots with Halo. With Microsoft gearing up for a huge Halo push with the Master Chief Collection rolling out to Steam, and the inevitably massive marketing effort that'll come alongside Halo Infinite, Ninja's comments can be seen as a hint about how Microsoft plans to market Halo in the future. My roots as a gamer started with Halo, so working with Microsoft and coming over to Mixer felt like a natural next step. Capturing all the great moments in gaming and sharing in the wins (and losses) with a positive, community-focused environment that we can all be proud of – that's why I'm here. But why does Microsoft want to take on Twitch at all? What's the point? The answer is engagement. Engagement and cross-selling
