Mark William Calaway began his Wrestling career with World Class Championship Wrestling (WCCW) in 1984. He joined World Championship Wrestling (WCW) as "Mean" Mark Callous in 1989. When WCW did not renew Calaway's contract in 1990, he joined the World Wrestling Federation (which later became World Wrestling Entertainment in 2002) as The Undertaker in November of that year and has remained with that company ever since.
