She has an on-off romantic relationship with her boyfriend Ken Carson, who first appeared in 1961. A news release from Mattel in February 2004 announced that Barbie and Ken had decided to split up, but in February 2006 they were hoping to rekindle their relationship after Ken had a makeover.
Barbie has had over 40 pets including cats and dogs, horses, a panda, a lion cub, and a zebra. She has owned a wide range of vehicles, including pink Corvette convertibles, trailers and jeeps. She also holds a pilot's license, and operates commercial airliners in addition to serving as a flight attendant. Barbie's careers are designed to show that women can take on a variety of roles in life, and the doll has been sold with a wide range of titles including Miss Astronaut Barbie (1965), Doctor Barbie (1988) and Nascar Barbie (1998).
Mattel has created a range of companions for Barbie, including Hispanic Teresa, Midge, African American Christie and Steven (Christie's boyfriend). Barbie's siblings and cousins were also created including Skipper, Todd (Stacie's twin brother), Stacie (Todd's twin sister), Kelly, Krissy, and Francie. Barbie was friendly with Blaine, an Australian surfer, during her split with Ken in 2004. Barbie was one of the first toys to have a marketing strategy based extensively on television advertising, which has been copied widely by other toys. It is estimated that over a billion Barbie dolls have been sold worldwide in over 150 countries, with Mattel claiming that three Barbie dolls are sold every second.
