During late 1999, WCW promoted various hardcore matches, bouts where there were no disqualifications or countouts, that mainly involved Norman Smiley and Brian Knobs.

In January 2001, the champion Meng signed a contract with the World Wrestling Federation (WWF) after his WCW contract expired.  Shortly afterwards, the promotion filed for bankruptcy and the WWF purchased all assets of WCW, and as a result, all WCW Championship copyrights were also property of the WWF.  After the purchase, the WWF used the WCW World Heavyweight Championship and WCW World Tag Team Championship in The Invasion storyline, in which former WCW wrestlers feuded with original WWF wrestlers before WCW's purchase, however, other WCW titles, including the WCW Hardcore Title, were not used.

WCW Hall of Fame: The World Championship Wrestling (WCW) Hall of Fame was an American professional wrestling hall of fame maintained by World Championship Wrestling (WCW).  It was established in 1993 to honor wrestlers who began their careers long before the 1990s, mostly alumni of the National Wrestling Alliance (NWA) and Jim Crockett Promotions (JCP), the predecessors of WCW.  Inductees received commemorative plaques that had their names & portraits inscribed on it.  Wrestlers were inducted by Gordon Solie, a senior announcer in professional wrestling, and received their plaque during the "Legends Reunion" segment at WCW's May pay-per-view event, Slamboree.  The WCW Hall of Fame was the second hall of fame established to honor professional wrestlers, after the creation of the World Wrestling Federation (WWF) Hall of Fame in February 1993.  After the 1995 Hall of Fame ceremony, WCW stopped the production of the Hall of Fame without a formal announcement.  In 2001, after WCW filed for bankruptcy, the WWF acquired all of its assets; this led to the formal stoppage of the WCW Hall of Fame.  The WWF, however, stopped producing its Hall of Fame ceremony after 1996.  In 2004, World Wrestling Entertainment (WWE), the WWF's successor, reinstated the WWE Hall of Fame, which included inductees that were alumni of WWE, NWA, JCP, and WCW.

In 1992, the team reformed in Smoky Mountain Wrestling, where they held the SMW Tag Team Championship ten times.  The duo also worked in the World Wrestling Federation and WCW.

List of WWF Light Heavyweight Champions: The WWF Light Heavyweight Championship was a professional wrestling cruiserweight championship operated by the World Wrestling Federation (WWF).  Only wrestlers that weighed less than 220 lb , called light heavyweights in professional wrestling, were allowed to challenge for the title.  From 1981 through the 1990s, the WWF had a business partnership with the Universal Wrestling Association (UWA), a Mexican lucha libre-based promotion, which resulted in the creation of the WWF Light Heavyweight Championship for the UWA.  When the UWA ceased operations in 1995, the title traveled to the Japanese New Japan Pro Wrestling (NJPW) promotion.  In 1997, as a result of the WWF owning the trademarks to the championship, NJPW was forced to return the title to the WWF.  One month later, the WWF began operating the title in the United States.  World Championship Wrestling (WCW) and its assets were acquired by the WWF in March 2001, which included the copyrights to their championships.  The WCW Cruiserweight Championship, a counterpart to the Light Heavyweight Championship, was one of these titles.  After acquiring WCW, the WWF used the Cruiserweight Title, among other WCW championships, during The Invasion storyline, which featured former WCW wrestlers feuding with original WWF wrestlers before WCW's purchase.  After The Invasion narrative ended in December 2001, the WWF replaced the Light Heavyweight Title with the Cruiserweight Championship, which had the WWF acronym added to its name.  World Wrestling Entertainment (WWE), the successor of the WWF, operated the Cruiserweight Championship until 2007, when the title was deactivated.
