History: Released on October 28, 2004, iPod photo (originally named iPod Photo — with a capital P for "Photo" — but renamed less than a month after its launch) featured a 220 x 176-pixel screen capable of displaying 65,536 colors, and the ability to store and display JPEG, BMP, GIF, TIFF, and PNG images. One millimeter thicker than the standard grayscale fourth-generation iPod, iPod photo could also play music for up to 15 hours per battery charge. It originally came in 40 GB and 60 GB versions, which cost $499 and $599 U.S., respectively. On February 23, 2005, Apple discontinued the 40 GB model; which included a FireWire and USB cable and a dock, introduced a lower-priced 30 GB model; which included only a USB cable and no dock, and dropped the price of the 60 GB model.
