But Google knows what people are interested in based upon searches. Google could approach companies with data saying: in this small geographic area, X-thousand searches were performed on this topic related to your business. You can use this information to really target your radio advertising. Radio is another medium. Google also knows what topic is hot instantaneously. Businesses could use this to alter radio advertising. Google knows more about me than my family (kind of worrisome.) Information is power.
