pple has sold its 100 millionth iPod, making the iPod the fastest selling music player in history.
The first iPod appeared in November 2001, and together with iTunes and the iTunes online music store, it has transformed the world of digital music.
It currently dominates over 75 per cent of the market for portable digital media players and has spawned an unprecedented system of over 4,000 accessories made specifically for the iPod that range from fashionable cases to speaker systems.
According to the company, more than 70 per cent of new US automobiles currently offer iPod connectivity.
Numerous companies, including giants like Sony and Microsoft, have tried but so far failed to challenge the iPod.
The latest effort is a joint initiative by Yahoo and SanDisk, which on Monday announced the launch of the Wi-Fi-enabled Sansa Connect, offering computer-free connection to Yahoo music and download services.
The device offers a 2.2-inch (5.58-centimetre) LCD screen and a 8GB flash hard drive and is priced at $250 in the US.
Over its five-year history there have been dozens of iPod models. Fans of the music and video player are now eagerly awaiting Apple's iPhone, which combines the functionality and design of the iPod with a cell phone.
AT&T's Cingular Wireless is set to begin exclusively selling the iPhone in the US for $500 and up in June.
