In March 2001, the WWF purchased World Championship Wrestling (WCW) and its championships were now also defended on WWF programming. Soon after, "The Invasion" took place in which the WCW/ECW Alliance was ultimately dismantled. At the 2001 Survivor Series pay-per-view, the title was unified with the WCW Tag Team Championship in a steel cage match. Then-WCW Tag Team Champions, the Dudley Boyz, defeated then-WWF Tag Team Champions, the Hardy Boyz, and were named the last WCW Tag Team Champions, as that title was deactivated, while becoming the new WWF Tag Team Champions.
