In October 2001, Apple changed the world yet again, by introducing consumers to the iPod. It was described as being able to have a "thousand songs in your pocket." The first iPods went on sale on Nov. 10, 2001.
The MP3 player was out long before Apple came up with the iPod, but Apple's ability to reinvent a market and make it easy to use created a product everyone wanted to have and couldn't do without.The original iPod is known for its famous click-wheel, which helped users scroll through their music library with ease. It originally came in 5 GB and 10 GB models, but in subsequent versions (the latest iPod Classic), Apple increased the amount of storage on the device to 160 GB. The original iPod connected via Firewire, but this later changed to USB, for both syncing and charging. The 5 GB version cost users $399, while the 10 GB version cost $499. The iPod spawned a line of products, including the iPod Mini, iPod Nano, iPod Shuffle and iPod Touch.
