Following on from @avavsystems post about Pocket Rockers, here's some more about them.

They were advertised with the tagline ‘Tiny Tapes, Tiny Players’ and came in a range of colourful designs. They were a fashion item as much as a music system (the tapes came with a belt clip that meant they could be worn) and were briefly popular enough to be banned in some schools.

Falling sales spelled the end for them in 1991.
