The majority of the English-speaking world has the same pronunciation of the letter "Z". "Zed," they say. Americans, however, have started pronouncing the letter as "Zee" which, by all accounts is incorrect. Why, you may ask, did America suddenly decide to pronounce a whole letter differently than the rest of the world? Well, based on my research, it has a lot to do with the education system. Kidding. It does have to do with a very simple song: THE ALPHABET SONG!!!!!! YAYYYYYY! As the result of "V" being the last syllable in the second last stanza "QRSTUV," the last stanza "WXYZ" sounds funny when you pronounce it "Zed" because it doesn't rhyme with "V." Believe it or not, the pronunciation is traced solely back to Sesame Street, 1971 when the song was purposefully changed to the incorrect "Zee." It was apparently a joke, but so many inner city children, who later became basketball players (probably) started to pronounce it that way that "The Man" couldn't change it back. And there you have it - Sesame Street changed the world!
