In 1968, Christie O'Neil made history as Barbie’s first African American friend, a pivotal moment during a time when racial representation was increasingly recognized as essential in various societal facets, including toys. Her debut marked a significant milestone for the toy industry, symbolizing a transformative shift in the cultural landscape and highlighting the importance of children from all backgrounds seeing themselves reflected in the toys they play with. She quickly became a favorite among collectors and children alike, establishing herself as a beloved character within the Barbie universe.

Her introduction followed that of Francie, Barbie's Caucasian cousin. She is recognized as the first black doll in the Barbie line, paving the way for future dolls, including Black Barbie, that represent a broader spectrum of ethnicities and backgrounds. This development contributed to a more inclusive approach in the toy industry, fostering a sense of belonging among children from diverse backgrounds.

Several Christie dolls were released over the decades, most recently a reproduction in 2021 and a 55th anniversary celebratory doll in 2023.
