WCW World Heavyweight Championship
As a result of the purchase, the WWF acquired the video library of WCW, select talent contracts, and championships among other assets. The slew of former WCW talent joining the WWF roster began "The Invasion" that effectively phased out the WCW name. Following this, the WCW World Heavyweight Championship was unified with the WWF Championship, the WWF's world title, at Vengeance in December. At the event, the WCW World Heavyweight Championship was decommissioned with Chris Jericho becoming the final WCW World Heavyweight Champion and the subsequent Undisputed WWF Champion after defeating The Rock and Steve Austin respectively. The WWF title became the undisputed championship in professional wrestling until September 2002 with the creation of the World Heavyweight Championship, spun off from the Undisputed WWE Championship as the successor to the WCW World Heavyweight Championship.
