Phillip Jack "Phil" Brooks (October 26, 1978), better known by his ring name CM Punk, is an American mixed martial artist and former professional wrestler. He was titled in the company as "the longest-reigning WWE Champion of the modern era", having held the title for 434 days from November 20, 2011 to January 27, 2013.
Punk is officially recognized as having the sixth-longest championship reign of all time.
During Punk's time in IWA: Mid-South, he had high profile feuds with Colt Cabana and Chris Hero while also rising to the top of the roster winning the IWA Mid-South Light Heavyweight Championship twice and the IWA Mid-South Heavyweight Championship on five separate occasions, beating stars like A. Styles, Cabana and even Eddie Guerrero for that Championship.
On June 24, 2006, Punk made his WWE television debut, performing in ECW, which was then a branch of WWE.Shortly before a TNA show on February 25, 2004, Punk had a physical scuffle with Teddy Hart outside of a restaurant that was broken up by Sabu.The scuffle reportedly stemmed from an ROH show in which Hart performed three unplanned spots putting several other wrestlers in danger of injury.He is the fifth longest-reigning champion in the title's history, after Bruno Sammartino & Bob Backlund (who had over 2000) and Hulk Hogan & Pedro Morales (who had over 1000).Punk's reign is the longest during the time it was called 'WWE Championship' while Hogan's is the longest during the time it was called 'WWF Championship' (narrowly eclipsing Backlund's second reign).
