Sony has a released a bunch of statistics covering the first four months of life of its new baby. Beyond regular sales figures (six million units so far, and nearly 14 million game sales), some of the more interesting numbers relate to how PlayStation gamers are engaging with the console's online features. We're told that half of all PS4 owners have been persuaded to cough up for a PS Plus subscription, which grants access to online multiplayer gaming as well as a number of discounted and free titles. Meanwhile, the 'Share' button on the DualShock 4 controller has apparently been used 100 million times to share recorded game highlights with the PS4 community, and 3.6 million gameplay broadcasts have been streamed over Twitch and Ustream -- a feature that still hasn't been enabled on the Xbox One. And who knows? The PS4's Twitch numbers might have been even higher if people hadn't gotten themselves banned for playing real-live strip poker.
