it's my understanding that for the month of october, yahoo is going to do the billing for both...then msn is going to take over once the transition is complete. apparently after 10/15, both yahoo and bing ads will be appearing on yahoo. i was told on oct 1st this new billing will go into affect. boy, i hope i heard this wrong but i don't think i did.
