Goldberg is best known for his time in World Championship Wrestling (WCW), where he performed between 1997 and 2001. Goldberg rose to fame in WCW with a lengthy undefeated streak in singles competition from 1997 to 1998; the official count was given as 173–0. During this time, he became WCW United States Champion and WCW World Heavyweight Champion and was regarded as the top star in WCW at the peak of the Monday Night Wars. He was also a one-time WCW World Tag Team Champion (with Bret Hart), making him along with Hart the fifth WCW Triple Crown winner. Following WCW's closure in 2001, Goldberg wrestled for All Japan Pro Wrestling (AJPW) between 2002 and 2003, and for WWE between 2003 and 2004, becoming a one-time World Heavyweight Champion in the latter. Goldberg headlined multiple pay-per-view events for WCW and WWE, including closing WCW's premier annual event, Starrcade, on two occasions (1998 and 1999). After 12 years away from the company, he returned to WWE in 2016 and headlined Survivor Series against Brock Lesnar.
Before he was a professional wrestler, Goldberg was a professional football player. After first retiring from professional wrestling, he began working as a commentator for the mixed martial arts promotion EliteXC until its closure. He hosted 26 episodes of Garage Mahal on the DIY Network from 2009–2011.
