Google already had written this off as a defensive cost to be sure. There's never been a surprise about this deal not being, prima facie, a good equity investment. However since it's been publicly traded, losing three points of market share would have had a much more material effect on the market cap, such that this made perfect sense to do. As for how much it generated, I'll bet it was breakeven. Assume Google had a 90/10 or 85/15 revshare with AOL, so Google made maybe $100M-$150M off this deal if the prior three years' numbers are correct above.
