Since the premiere of the children's television program Sesame Street on November 10, 1969, it has included what writer Malcolm Gladwell has called "the essence of Sesame Street—the artful blend of fluffy monsters and earnest adults". The original cast, chosen by original producer Jon Stone, consisted of four human actors—Matt Robinson, who played Gordon; Loretta Long, who played Gordon's wife, Susan; Will Lee, who played Mr. Hooper; and Bob McGrath, who played Bob. Unlike most children's television programs at the time, the producers of Sesame Street decided against using a single host and cast a group of ethnically diverse, primarily African American actors/presenters, with, as Sesame Street researcher Gerald S. Lesser put it, "a variety of distinctive and reliable personalities".
