Guess it depends on how you define it. If the affiliate group manages more than a couple of casinos (and there are many of those, Fortune Affiliates, Brightshare, Revenue Giants, etc. etc.), then they are some type of network. The question is more one of ownership I guess, since the casino owners may be the affiliate program owners as well. It is interesting that no one has really tried to consolidate the industry and all of the networks that are out there are rather small.
