Sony released the PlayStation Move in September 2010. This was to compete with Nintendo's other motion controllers. Microsoft released the Kinect. The Kinect does not use any controllers and makes the users the "controller". Kinect sold 8 million units in its first 60 days. The Guinness World Record named it the "fastest selling consumer electronic device". Both the Playstation 3 and Xbox 360s controllers can be used wired or wirelessly. The first handheld game consoles of this generation was the Nintendo DS.
