Nintendo released the Wii in December of 2006 as a competitor of other gaming consoles on the market such as the Playstation 3 or Xbox 360. Wii replaced the GameCube and was discontinued in 2013 when the Wii U replaced it. The top selling game for the console was Wii Sports, with 82 million copies sold overall. In 2015, it was announced that almost 1 billion Wii games were sold. Celebrity Sports Showdown, Dance Dance Revolution, and Gold’s Gym Cardio Workout were popular games exclusively associated with Wii. In business news, Wii was a topic for potential copyright infringement or patent lawsuits.
