Google AdSense in newspapers: Google reserves advertising space in every circulation. This space is used depending on context.

Google AdSense and Wi-Fi: Google will cover the globe with free POPs. Google will know your exact location and this fact will be very useful for context ads.

Google AdSense and mobile phone: Google redeems cellular communication operator and provides services for free, In return you have to hear short advertising ads before you can speak. These ads are also selected according to context.

Google AdSense on roads: LCD screens are placed on roofs of taxies, on sides of buses and etc. Such screens also have connections with Wi-Fi POPs and ads are different depending on the place, current time and so on.

Such forecast seems to be too much pessimistic and unsophisticated. It is possible that Peter Forret is some kind of paranoiac and is afraid that someday Google will transmit its ads directly to his brains. But who knows!
