For what it's worth, this is from the entry in Wikipedia:

"Daz Studio is designed to allow users to manipulate relatively ready-to-use models and figures as well as other supporting 3D content. It is aimed at users who are interested in posing human and non-human figures for illustrations and animation. It was created as an alternative to Poser, the industry-leading software in use for character manipulation and rendering. Daz 3D began its business model selling 3D models of human beings (and a few non-humans), as well as giving away a few of the more popular base models for free from time to time, and clothing and props for the same, and all of these models were constructed to be used in Poser. Daz eventually created their own character-manipulation software, first for sale and later distributed for free (originally just the base edition, but eventually even the "pro" version)."
