ipod

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 organizer 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 awayful,"so Apple decide to develop its own. The product was developed in less than one year and unveiled on 23 October 2001. Jobs announced it as a Mac-compatible produced with a 5 GB hard drive that put"1,000 songs in your pock. Apple did not develop the ipod software entirely in-house, instead using portal player's reference plate form based on two ARM cores. The platform had rudimentary software running on a commercial micro kernel embedded operating system.

Portal player had previously been working on an IBM-brocaded MP3 player with Blue tooth headphones.Apple contracted another company, Piox, to help design and implement the user interface. As development progressed, Apple continued to define the software's look and feel. Starting with the ipod Mini, the Chicago font was replaced with Espy Sans. Later ipods switched forts again to podium Sans a font similar to Apple's corporate font, Myriad. ipods with color displays then adopted some Mac OS X themes like Aqua progress bars, and bushed metal meant to evoke a combination lock.In 2007 Apple modified the ipod interface against with the introduction of the sixth-generation ipod classic and third-generation ipod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right.

In September 2007 during the course of a lawsuit with patent holding company.Apple drew attention to patent for a similar device that was developed in 1979.Kane Kramer patented the idea of a "plastic music box" in 1979,which he called the IX.He was unable to secure funding to renew the worldwide patent, so it lapsed and Kramer never profited from his idea.
