McMahon began appearing regularly on WWF in 1999 as a part of a storyline with The Undertaker. After a brief on-screen relationship with Test, she was engaged to Triple H—whom she married both on-screen and later in real life—which resulted in The McMahon-Helmsley Faction storyline. She has held the WWF Women's Championship once. In 2001, she was the on-screen owner of Extreme Championship Wrestling during The Invasion. The following year, she was the SmackDown General Manager, but stopped appearing regularly on television after an "I Quit" match with her father Vince.
After only making sporadic appearances for several years, McMahon began appearing regularly on Raw in 2008 as the Raw brand general manager before disappearing once again. By mid-2013, McMahon returned to regular on-air appearances in the WWE, this time under the gimmick of an unctuous, judgmental, bullying owner along with on-screen chief operating officer her husband, Triple H. Together as a power couple known as "The Authority," they make what are often shady decrees while claiming only to be concerned for "what's best for business," all the while romanticizing each other in the process with public displays of affection. The Authority later expanded into a stable made up of Seth Rollins, Kane, Jamie Noble, and Joey Mercury, and included with its co-leaders Triple H and Stephanie McMahon.
