A Boombox - also known as ghetto blaster, Jambox, Wogga box, or radio-cassette - is a name given to portable stereo systems capable of playing radio stations and recorded music (usually cassettes and/or, since the early 1990s, CDs), at relatively high volume. As befits its portability, Boomboxes can be powered by batteries as well as by line current. The first boom boxes were introduced by various companies in the late 1970s.
