In 1990 Sesame Street kicked-off four-year curriculum focusing on race relations. Episodes focused on race, about getting along, and appreciating everyone's similarities and differences. Seasons produced during the initiative focused on African American culture (Season 22), Native American culture (Season 23), Latino culture (Season 24 and dealing with racism (Season 25). Dulcy Singer said of season 22's theme, "We're recognizing and celebrating cultural differences - talking about color of skin, hair texture, situations where a child might be left out from a group because of his color." Of season 23, Singer said: "Last year the series emphasized African-Americans, showing viewers that people who look different or have a different langue or culture can be good friends. This year' Sesame Street' wants young viewers to see how American Indian children live and recognize general cultural similarities and differences among American Indian nations" Of season 24, Valeria Lovelace said: "There will also be more emphasis on the Spanish language and Latino culture."
