Then, Braun continued to produce state-of-the art radios and audio equipment, and soon became well known for its "high-fidelity" audio and record players, including the famous SK line. In 1954, the company also began producing film slide projectors, a mainstay of its business for the next forty years. By 1956, Braun was marketing the first fully automatic tray film slide projector, the PA 1. Braun AG slide projectors all utilized a linear or straight tray as opposed to a carousel-type design, which allowed the projector to remain small and compact.
The 1950s also marked the beginning of the product that Braun is most known for today: the electric shaver. The S 50 was the first electric shaver from Braun.
