An add-on for the Wii Remote called the Wii MotionPlus was released in June of 2009. It added a gyroscope and supplemented the accelerometer, allowing the Wii Remote to sense movement much more precisely.
The Wii Remote Plus was later released. It built the Wii MotionPlus into the remote, allowing it to fit into other accessories such as the Wii Zapper.
