Google’s founders are obsessed with precise numbers – Google is a corruption of googol (10 to the power of 100); they offered 14,159,265 shares when the company floated (the first eight digits for Pi after the decimal point); and my search to check that fact took 0.25 seconds, Google tells me.

The power of 10 is therefore significant enough to the Mountain View company that its 10th birthday this month has been marked by perhaps the most important product launch in its history.
