Broderbund Software, Inc. (formerly stylized as Brøderbund) was an American maker of video games, educational software, and productivity tools. Broderbund is best known for the 8-bit video game hits Choplifter, Lode Runner, Karateka, and Prince of Persia (all of which originated on the Apple II), as well as The Print Shop—originally for printing signs and banners on dot matrix printers—and the Myst and Carmen Sandiego games. The company was founded in Eugene, Oregon, and moved to San Rafael, California, then later to Novato, California. Broderbund was purchased by The Learning Company in 1998.
