PBS Digital Studios continues their great work with Inventors. Inventors is a series of portrait videos by filmmaker and photographer David Friedman, chronicling the work of contemporary inventors from all walks of life. It offers rare glimpses into the inspiration for their creations. Here we take a look at the very first software patent and the invention of the digital camera.

There's a good chance that you've heard about the controversy around software patents, but you probably don't know the story of Martin Goetz, who got the very first software patent in 1968. Today, some people say that software patents owned by big companies end up stifling innovation in small companies, but the first software patent was a tool that enabled a small company to compete against a big corporation.

Steven Sasson invented the digital camera in 1975 while working at Kodak in Rochester, NY. In this video, he shows off features of the original prototype, and describes how digital imaging has expanded beyond anything he could have imagined.
