Google is celebrating its tenth birthday this month — so how is it doing compared to Microsoft, which is a ripe old 33? Microsoft is still the big dog, earning three times the revenue in the last year. But Bill Gates and company had only booked $140 million in revenue by its tenth year. Google employees are also punching above their weight, booking $1 million per head to Team Redmond's $672,000. If Google figures out how to make money on anything besides search advertising, the $99 billion market value differential might evaporate in time for a bar mitvah in Mountain View. [NYT]
