Cebu gdev, the term is "advertisers." They don't "provide" advertisements - they advertise. They don't see ads as a service for game developers, you see - they see them as marketing tools to benefit themselves.
Anyway, I just thought you needed a little clarification on the nature of advertising. Someone else can tell you about finding advertisers or ad aggregators or how ads on Facebook games work.
(Also, you posted your business question in the Programming forum, so I moved it to the appropriate board.)
yeah thanks for the advice and moving the thread, i was confused where to start the thread yesterday
