A family of extremely popular digital media players from Apple, introduced in 2001 for the Mac and a year later for Windows. The combination of sound quality and unique click wheel user interface made the iPod one of the most successful consumer electronics products in history. More than 100 million were sold within five and a half years along with 1.5 billion songs from Apple's iTunes online store. See click wheel.
Originally for music only with a monochrome screen, color screens, photos and video were soon added, and third-party games and applications were also developed. However, in 2008, the second generation of the operating system for the iPod touch and the iPhone relaunched the devices as handheld computer.
iTunes and the AAC Audio Format
Apple's iTunes software is installed in the user's computer. It is used to organize and download content to the iPod, keep the iPod's software up-to-date and to buy new content from the online Apple store. It ensures that protected AAC audio and MPEG-4 video files purchased from the store are played on specific iPods, iPhones and computers. iPods also support unprotected MP3 and AAC files that come from ripping CDs, file sharing networks and music stores that sell unprotected files.
AAC is considered better quality than MP3 at the same recording rate, and iTunes lets users rip songs from their CDs into MP3 and AAC, both of which result in a file about 10% the size of the original song on the CD. However, for audiophiles with large capacity iPods, the Apple Lossless format maintains CD quality, but files are five times larger than highly compressed MP3 and AAC.
iPods do not play Microsoft's Windows Media Audio (WMA) format. However, numerous utilities convert WMA to MP3, and the Windows version of iTunes converts WMA to all formats that iTunes and the iPod support. See iTunes.
Batteries
Unlike other electronic devices, the rechargeable battery in the iPod is sealed and must be sent to Apple for replacement, which is free under warranty, but not thereafter. However, non-Apple sources offer replacement batteries and instructions for opening the case. See iPod compatible, iPod finger, iPod car adapter, car podding, pod slurping, MP3, AAC, FairPlay and iPhone.
File Formats
The iPod displays JPEG, GIF, BMP, TIFF and PNG images and plays MPEG-4 and H.264 video. It supports the following audio formats.
