iPod is a line of portable media players created and marketed by Apple Inc.
The iPod line came from Apple’s “digital hub” category, when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players “big and clunky or small and useless” with user interfaces that were “unbelievably awful,” so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple’s hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Jonathan Ive. The product was developed in less than one year and unveiled on October 23, 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put “1,000 songs in your pocket.”
