No one can say definitely who formulated the boombox, which is also named as ghetto blaster. In the mid 1970s, the thought of a handy stereo turned popular. A view at the past times of the boom box discloses that Sanyo, Panasonic and Marantz were the innovators. After that, the idea ignited in the 1980s and early 1990s. This state would turn even more far-flung when break-dancing turned popular. Nowadays, the launching of CD and mp3 players has significantly reduced the reputation of boom box.
