Apple iPod MP3 player, 1st generation with 5 GB hard disk

When the first portable MP3 players hit the market in 1998, their flash memory often held only 20 tracks. The 5 GB hard drive featured in the 2001 iPod gave you "1,000 songs in your pocket." The iPod brought the MP3 player from the dark corners of online software pirating by connecting it to the iTunes music store. With iTunes, you could legally acquire digital music for the first time and listen to it on multiple players. The iPod is the best-selling MP3 player in the world with over 400 million sold.
