I understand that, but at least google has expanded in other areas. that is my point, if search somehow no longer generates that kind of revenue google has several areas where they can fall back on.google's revenue is still 99% advertising through its search engine. They are still the primary search engine and it is still the biggest part of their business. The reason why facebook is failing is because big advertisers that support facebook are pulling their money away, like GM pulled away 25 million. Facebook does not work for big brands that want to advertise online .
That's why you hear about Facebook trying to get into the cellphone business. I wonder how that will turn out to be honest, they do have all the information needed to get started. It can possibly change the game if everything is integrated seamlessly.
