On December 27th, 1998, "Big Sexy" Kevin Nash ended Bill Goldberg's legendary undefeated streak in World Championship Wrestling (WCW) at their Starrcade pay-per-view event, which was WCW's biggest annual PPV of the year.
Goldberg went into the event as the reigning WCW World Heavyweight Champion. Nash's victory over Goldberg marked the beginning of Nash's first WCW World Title reign. He would go on to become a four-time WCW World Heavyweight Champion before WCW went out of business.
