过去，亚马逊在视频业务方面与Netflix相似，提供电影、电视和原创剧的流媒体视频服务，这让它与后者没什么区别。收购Twitch能为亚马逊带来YouTube式的垂直领域视频，而且内容由用户产生。Twitch能提供海量游戏视频，这些都可以供亚马逊使用，比如不断为Prime用户增加视频内容，也让机顶盒Fire TV、Fire Phone和Kindle Fire等设备成为很好的游戏视频平台。
In a surprise move, Amazon has bought video-game streaming service Twitch for $970m (£585m).
Earlier in the year, Google's YouTube had been reported to be in late-stage acquisition talks for a similar amount.
Founded in 2011, Twitch - formerly known as Twitch.tv - allows users to watch other people play video games.
As of July of this year, the service had over 55 million unique monthly viewers.
"Broadcasting and watching gameplay is a global phenomenon and Twitch has built a platform that brings together tens of millions of people who watch billions of minutes of games each month," said Amazon chief executive Jeff Bezos in a statement.
"We look forward to learning from them and helping them move even faster to build new services for the gaming community," he added.
The move is seen by many analysts as helping Amazon in its quest to beat other streaming video sites like YouTube and Netflix.
Monday, multiple reports indicated Amazon was in late-stage talks to acquire Twitch. The news came as a big surprise because just last month it was reported that Google had agreed to acquire Twitch for about $1 billion. That deal, however, was never officially confirmed.
