The premise of the series is to emulate professional wrestling, specifically that of WWE, formerly known as the World Wrestling Federation (WWF). The series began with WWF SmackDown! on the original PlayStation and has continued as an annual release. It was originally exclusive to PlayStation platforms until 2006's WWE SmackDown vs. Raw 2007, which expanded the series to other platforms. In 2013, the series was rebranded as WWE 2K, beginning with WWE 2K14.
