Perhaps. But even if so, after less than 6 years at that rate(allowing for deaths) they would be relying on children less than 6 years old for new, unique visitors. Not noted as a major internet ad-clicking user group. Moreover, this calculation should have begun pretty much with Google's start. So, in theory, by now there are very few unique visitors available, if any. I'm not going to do the math, but available unique visitors is a series along the lines of (world's population of 6.5 billion - unique visitors month 1), (6.5 billion - unique visitors month 1 - unique visitors month 2), etc. If 90 million was the figure for one month after about 84 months, and assuming a reasonablly smooth curve that is probably logarithmic in nature, it would seem that most of the world has been used up already.
I doubt though that even the 90 million figure does represent unique people, as implied in Dave's calculation, in any case. For starters, I would think that a large percentage of visitors would access from both home and work/school, reducing the number of real pople, although these two locations would be seen as "unique visitors." On the other hand, a family of six using the same computer would be seen as one unique person, as would a library computer.
Most importatnly, and most in line with reality, is that is could easily be that everyone who uses
Google does so every month, the statistical period used by Comscore it seems. If this were the case, then Google's total user base would be 90 million (the truth probably lies somewhere in between 90M and 1080M). In this case, the crude figure, with no allowance for multiple use of the same address, or single users using multiple addresses, would be closer to $140 per year. So, we have a range of $16 to $140 per year per person.
So, Rumblepup, you may be worth more than you think.
