Corbis is a digital imaging/stock photography company founded by Bill Gates in 1989. The company is currently developing one of the world's largest resources of visual information - a comprehensive digital archive of art, prints, posters and photography from public and private collections around the globe.
Corbis archives over 11,000,000 photographs and other art, prints and posters in a facility deep within a former limestone mine in Boyers, Pennsylvania.
The mine presents an ideal, highly secure and easily climate-controlled environment for Corbis to successfully preserve the photographic media, art, prints and posters.
