In 1980 Doug and Gary Carlston founded Broderbund, also known as Brøderbund. What they didn't knew back then was that this company would create some good selling and excellent games. Stunts (aka 4D Sports Driving), the Prince of Persia series, the Carmen Sandiego series and Lode Runner are just some of the titles that are famous. Open a certain download site and you'll see one of these games.
