Google Street View is a huge endeavour. I’m surprised that no-one in Mountain View has yet come up with Today’s Invention: ads pasted into its imagery.
The intrepid search folk know all about which images are viewed most.
They could use this information to help price their virtual ads.
Say I want to have an advert for my patented corn plasters appear in virtual Times Square. That would cost me say $1000 a second.
I might choose instead to have the ad appear on the wall down the street from my house, at 1$ per day.
Online users might get served different inserted ads, depending on where their ip address was located.
In any case, people could pay for their version of Street view to carry no adverts, but if not, they could also click on virtual hoardings and buy stuff.
