I&#x27;m new this this, so help me out.<p>If this is true (particularly the reference to advertising=1.27% of GDP) then an expectation of future revenue of all FaceGoog-advertising will be in the range of 1.27% x (GDP of US) x 50% of advertising market. This works out to 115 Billion per year. Google+FB&#x27;s market combined current revenue is $93 Billion.<p>Is that reasonable? If so, isn&#x27;t FB&#x27;s market cap a little silly?
