In 1983, Audio Technica launched the Sound Burger, a portable turntable, to compete with the Walkman. Much like cassettes in a Walkman, the Sound Burger let users play records anywhere, as long as they played on flat surfaces. This made them much less useful than a Walkman, which people used commonly while walking. Additionally, consumers had to carry their bulky vinyl and made the unprotected turntable records vulnerable.
