Reuters – Google Inc’s YouTube unit has reached a deal to acquire videogame-streaming service Twitch for more than US$1 billion, according to a report in Variety, the entertainment news publication.

The all-cash deal is expected to be announced “imminently”, according to the report on May 18, which cited unnamed sources.

Officials at Google and Twitch declined to comment on the matter.

San Francisco-based Twitch allows consumers to broadcast live video streams of themselves playing videogames and includes social networking features that allow video game fans to communicate with each other during the broadcasts. The company says more than 45 million gamers visit its site every month.
