The iPod Classic (stylized and marketed as iPod classic and formerly just iPod) is a portable media player created and formerly marketed by Apple Inc. There were six generations of the iPod Classic, as well as a spin-off (the iPod Photo) that was later re-integrated into the main iPod line. All generations used a 1.8-inch (46 mm) hard drive for storage. The "classic" suffix was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007. Prior to this, all iPod Classic models were simply referred to as iPods. It was available in silver or black replacing the "signature iPod white". On September 9, 2014, Apple discontinued the iPod Classic. The sixth-generation 160GB iPod Classic was the last Apple product in the iPod line to use the original 30-pin iPod connector and the iconic Click Wheel.
