When I ask other people if they've ever clicked online advertisements - I usually hear a resounding 'no'. Actually, I have never met a person who clicked an ad-word or some sort of an online advertisement. I wonder who clicks these ads and how it came to be a multi-billion dollar business.
To illustrate my point. What is the market cap of iPhone & how many people you know have an iPhone; What is the market cap of Kindle & how many people you know have a Kindle; Compare that to market cap of Online Ads and how many people you know have clicked an online advt.
