Joe DiMaggio's 56-game hit streak ... Wilt Chamberlain's 100 point game ... Jack Nicklaus' 18 Majors.
The professional sports world is filled with record feats that have stood for decades and may stand for decades more if not forever, and quietly this year a worldwide box office milestone was set that may also stand the test of time.
Sometime last week the Marvel Cinematic Universe passed $5 billion dollars in the worldwide box office in 2019. That's a total that obviously has not been surpassed before and may never again if ticket price inflation doesn't significantly outpace moviegoers increasing tendencies to stay put in their home theaters as we get into the 2020s.
Captain Marvel ($1,128,274,794), Avengers: Endgame ($2,795,092,335) and Spider-Man: Far From Home ($1,096,972,490) now have $5,020,339,619 worldwide and counting between them and crossed $5 billion mark sometime last week.
Of course Disney can't claim the milestone as Far From Home is technically a Marvel Studios production but a Sony release, but put another way, no actor may every appear as the same character in films that grossed over $5 billion in a calendar year ever again, as Samuel L. Jackson did appearing as Nick Fury in all three films.
Marvel Studios may be years away - if ever - from coming close to replicating the all-time global record levels of Endgame's success, which anchored the ability to cross $5 billion. The studios' most realistic path to that worldwide milestone again may be if they expand their release slate to four in one year from their usual two or three.
2020 will feature two MCU releases - Black Widow in May and Eternals in November and to put it in perspective Marvel Studios will likely do cartwheels if both productions top $2 billion combined worldwide.
