The seventh generation of consoles began with the release of the Xbox 360 in 2005. This was followed by the Wii and the PlayStation 3 in 2006. The seventh-generation featured widespread implementation of HD-ready graphics, media centers, and wireless game controllers, as well as online services for all consoles. The PS3 also has Blu-ray Disc compatibility. The Wii implemented an innovative game controller that features full motion sensitivity and is wielded like a remote, with limited button interaction. In response, the PS3 introduced tilt-sensitive functionality with its controllers. The Wii's motion sensitive controls and focus on family-friendly games, while alienating some hardcore gamers, helped the Wii to become the best-selling console of the seventh-generation. The high price of the PS3 had initially caused slow sales, but numerous price cuts and efforts to bring feature-parity between it and Xbox 360 were made in the years following. It was generally successful as the PlayStation 3 steadily increased in popularity, resulting in lifetime sales to be nearly equal to that of the Xbox 360.
