Here is something that could reasonably occur in 1 year: - Number of people connected to internet grows by 7% - Average income of existing users grows by 2% - Amount of time on internet spent by average user grows 7% - Number of ads served to an average user per hour of internet time grows 2% - Effectiveness of an average Google ad grows 9% Total growth in Google revenue: 30% Also keep in mind that most of Google's costs do not need to rise in line with revenue - it wouldn't take twice as many employees to serve twice as many ads. Including dividends, I would put the chance of a $1.5 trillion valuation in 10 years at 60%
