#2 Bruno Sammartino's 2803-day reign as WWE Champion
Speaking of records that will never be broken. Bruno Sammartino's reign as WWE Champion began in 1963 and it was in 1971 that somebody finally managed to beat him for the title. Stories go that when Ivan Koloff beat Sammartino to win the Championship, people in Madison Square Garden started to cry seeing their hero's title run coming to an end.
Today, it is rare to see somebody to hold the title for even a year. Sammartino's record is so absurd, that the WWE had to market CM Punk's 434 days as WWE Champion as 'the longest reign of the Modern Era'. Just for context, even if CM Punk held the WWE Championship for 434 days on five more occasions, he would still be 199 days short of Sammartino's reign.
It might be hard for people to wrap their heads around how long 2803 days as champion really. To put it into perspective, 2830 days ago The Shield did not exist, The Undertaker was still undefeated at Wrestlemania and CM Punk had not even won his first WWE Championship.
