> And advertising spending is increasingly exponentially. Good numbers on ad spend are available here [1]
I don't see a single place in that PDF that lists historical ad spend data. You do realize that is a "forecast" not a mearement?
And even that forecast contradicts the point you are trying to argue. It projects that ad spend will grow exponentially...at a rate lower than GDP.
So again, the only evidence here that the Internet increased advertising spending is by arguing that the Internet increased GDP.
> Ad spending was estimated at growing around 14% per year
This is false. The only place that numer was used in your cited text was here:
>> We forecast paid search to grow at an average rate of 14% a year to 2016
So that isn't a measurement, it is a forecast. It is also not for all ad spending growth, but for "paid search".
I too dislike mass advertising, but if you wanna argue against it you need to do MUCH better.
