What companies produce Ipod stereo systems?

In 2004 Hewlett-Packard (HP) abandoned their own planned music player, to be called the Pavilion, and signed a deal with Apple to sell iPods produced by Apple with a HP badge on the back. This gave Apple access to retailers where they did not have a presence but HP did. However with the increasing popularity of the Apple iPod very few HP iPods were sold and HP terminated the deal with Apple in July 2005. (See links below)
