Quote:Guidelines for distributing Productions with Blizzard Content

Note that Blizzard Entertainment's restriction that Productions be limited to "non-commercial" uses also means that you may not license a Production you have created to another company for a fee, or for any other form of compensation, without specific written permission from Blizzard Entertainment to do so. Blizzard Entertainment reserves the right to use its products for all commercial purposes. The only exceptions to this rule are if you participate in partner programs with YouTube, Justin.tv, Blip.tv, Own3d.tv, or Ustream.tv (the �Production Websites�) whereby a Production Website may pay you for views of a Production if you are accepted into their partner program.
