The Walkman has been cited to not only change people's relationship to music but also technology, due to its "solitary" and "personal" nature, as users were listening to their own music of choice rather than through a radio. It has been seen as a precursor of personal mainstream tech possessions such as personal computers or mobile phones. Headphones also started to be worn in public. This caused safety controversies in the US, which in 1982 led to the mayor of Woodbridge, New Jersey banning Walkman to be worn in public due to pedestrian accidents.
