Sony introduced the Walkman in 1979, facing skepticism but ultimately capturing the public's imagination and becoming a cultural icon.
During the 1990s, the Walkman experienced its golden age, expanding its product line and maintaining its premium position in the market.
The arrival of digital music and MP3 players, particularly Apple's iPod, marked the decline of the traditional Walkman as Sony struggled to compete.
While the cassette Walkman is no longer produced, Sony continues to keep the brand alive through high-end digital music players, adapting to changing market demands.
