Major League Baseball

1969–1992


Major League Baseball (MLB) was founded in 1903, but did not adopt an official logo until 1969, when it commissioned the red, white and blue "Batter" logo in preparation for the Professional Baseball Centennial Celebration. The logo's authorship was disputed until 2008, when Jerry Dior was confirmed to be behind the design. Dior stated that he created the logo during a single afternoon in 1968, using photography of numerous MLB athletes as reference (contrary to popular belief that he modeled it after Hall of Famer Harmon Killebrew).

1992–2019
For the 1992 season, the original logo had its colors slightly darkened, coinciding with its implementation on every cap used in the league.

2019–present


On March 20, 2019, MLB changed the color shades of its logo again, this time to match those of the American flag, in commemoration of the 150th anniversary of professional baseball. The league's full name was also officially removed from the logo and replaced with its acronym in a new typeface; however, only the symbol is still used in most cases.
