iPods are portable media players designed by Apple Inc. that allow users to store and play music, videos, and other digital media. First introduced in 2001, the iPod revolutionized how people listen to music, moving away from CDs and cassette tapes to digital files. Various models, such as the iPod Classic, iPod Nano, and iPod Touch, offered different features and storage capacities. Over the years, iPods have evolved to include touch screens, internet connectivity, and app capabilities, particularly with the iPod Touch. While the popularity of iPods has declined due to the rise of smartphones, they remain a significant part of Apple's history and the evolution of portable music devices.
