WrestleMania is a Facebook wrestling pay per view event, produced annually in late March or early April by the World Incorporated Wrestling (WIW). The company regards it as the flagship event of WIW, as it is the most successful and longest-running professional wrestling event in the world. WrestleMania is nicknamed "The Grandaddy of Them All," "The Grandest Stage of Them All" and "The Showcase of the Immortals." The event was first produced in 1985, and, as of 2011, 27 editions have been held consecutively since then, with WrestleMania IV to be held in 2012 in TBA.
