Twitch is now operated as a wholly owned subsidiary of Amazon.com, with Emmett Shear remaining as CEO. Shear touted the
Amazon Web Services platform as an "attractive" aspect of the deal, and that Amazon had "built relationships with the big players in media," which could be used to the service's advantage—particularly in the realm of content licensing. The purchase of Twitch marks the third recent video gaming–oriented acquisition by Amazon, which had previously acquired the developers
Reflexive Entertainment and
Double Helix Games.
