24. RC-M90 Boombox
Year Invented: 1991
Arguably the most iconic boombox there is, the JVC RC-M90 has been referenced numerous times in music and film, and it even appeared on a few album covers (like Solid Gold Hits by the Beastie Boys and LL Cool J's Radio.) While the boombox itself is an icon of everyday design, the RC-M90 has become an icon of pop-culture as well.
