1. New York Yankees

Designer: Louis B. Tiffany

Year Logo Introduced: 1909

No sports logo has the power of the interlocking "NY" worn by the New York Yankees. It transcends the game of baseball, serving as Big Apple's symbol (alongside Milton Glaser's famous I heart NY). The history of the lettering foreshadows its eventual adoption by the five borough's greater population-Louis B. Tiffany's design was created for a medal given by the New York City Police Department to Officer John McDowell, the first NYC policemen shot in the line of duty. It first appeared on a baseball uniform for the team, known then as New York Highlanders, in 1909, eventually becoming the Yankees standard in 1922.
