The Six Million Dollar Man is an American television series about a former astronaut with bionic implants working for a fictional government office known as OSI. The series is based on the Martin Caidin novel Cyborg, which was the series's proposed title during pre-production. Following three television movies aired in 1973, The Six Million Dollar Man aired on the ABC network as a regular series for five seasons from 1974 to 1978. The title role of Steve Austin was played by Lee Majors, who subsequently became a pop culture icon of the 1970s. A spin-off series, The Bionic Woman, ran from 1976-78. Several television movies featuring both eponymous characters were also produced between 1987 and 1994.
