ATT may not be the only one landing a big acquisition this weekend. Variety claims that Googles YouTube division has struck a deal to buy Twitch, the game-focused video streaming service, for more than $1 billion. Neither side is commenting on the rumor, but its easy to see why YouTube would splurge — Twitch has more online viewers than some big sports networks, and a takeover would immediately secure a larger presence in the gaming world.
