A Walkman is a portable cassette player that was first introduced by Sony in 1979. It allowed people to listen to music on the go using cassette tapes, which were small and easy to carry. The Walkman revolutionized how we enjoyed music, making it possible to have a personal soundtrack while walking, jogging, or traveling. Over the years, the Walkman evolved to include CD players and digital music formats. It became a cultural icon, symbolizing the rise of portable music. Today, while smartphones have largely replaced Walkmans, they remain a nostalgic reminder of a time when music was enjoyed through tapes and CDs.
