You are probably correct that the other revenue sources are not negligible. I do wonder however how Google would fare if their ad revenue took a major hit. I don't think their other offerings could sustain the current juggernaut that they have become. I suppose given their cash reserves they could figure something else out. It certainly seems though that most of their new products are just more ways to push advertisements and of not that much utility in the first place.
