Portable casetteplayer

 

 

The walkman was not a real invention, because Philips had already invented the compact cassette in Hasselt 16 years earlier and a portable device with the same functions and properties to play it. This Norelco Carry-Corder 150 came out in 1965. It was the first portable cassette player. Portable is a relative term here, because the music player weighed more than 1.5 kilograms. Still, the Carry-Corder 150 marked the beginning of the portable cassette player revolution. 

In the first five years, 1 million of these devices were already on the market. The first version of the Walkman was launched on June 21, 1979. The device, marketed by Sony, quickly became extremely popular with the young. Other manufacturers rushed to release such devices, all of which were colloquially called walkman but officially referred to as "portable cassette player."
