this is how networks and publishers are existing and can concentrate on just generating traffic.

i have seen so many who thought they can do it alone after they had some nice numbers and all of them struggled.

even the big tubes would not be able to make good money without all this competition and the are using networks (or owning them).

media buy is a taff biz and the most who made money with traffic 15 years ago would not stand this competition anymore.
these are the ones who call it a "ponzi" or a "money grave".

but I am in this biz and I make millions of revenue every year with more or less the same 100-150 buyers. I really doubt that they pay all this big sums because they love my cute brown eyes - if so: thanks to all my customers ;-)
