The Public Broadcasting Service, which features nudity in anthropological documentaries as well as some films, was the first network to display national programming that featured frontal female nudity on television. In 1975 (with a rerun in 1986), the PBS "National Geographic" special "" looked into parts of the human body and included in its opening scenes a fully nude woman in an artist's model pose; probably less for this than the innovative micro- and interior cinematography, this was for more than half a decade the most popular single program broadcast on the network.
