When the first iPod was launched in 2001, it could store 1,000 tracks. Today there are more than 90 million songs on Apple's streaming service.
The iPod Touch was designed by Tony Fadell, who later invented the iPhone, which quickly overshadowed the iPod. Apple last updated the iPod in 2019.
There have been various iPod models over the years — including the nano and shuffle — but the iPod Touch, which was released in 2007, paved the way for the iPhone, and is the last model to be discontinued.
Apple says it will remain available to buy "while stocks last".
The gadget had "redefined how music is discovered, listened to, and shared", Greg Joswiak, the senior vice-president of worldwide marketing at Apple said.

BMW introduced the first car entertainment system with a built-in iPod system, and within a few years, most car manufacturers had followed suit.

"When Apple created the iPhone it knew that it would ultimately mean the beginning of the end of the iPod," Ben Wood, chief analyst at technology advisory firm CCS Insight, told the BBC.
