Facebook just changed email addresses listed in its members contacts with its own email address system in an attempt to shut out Google.

You can see why. Google are eating the web.

Take Youtube for example. How much money is Google making off Youtube? A lot. As usual Google provide no firm evidence.

But Wall Street estimates the video site, now also the second biggest search site behind its owner Google, will generate more than $3.6 billion in gross revenue this year. After giving some of that to partners, Google will probably record net revenue of $2.4 billion, says Citi’s Mark Mahaney.

That revenue estimate is 50% greater than Yahoo’s Display Advertising total and the same as Netflix’s total subscription revenue. “I doubt whether most investors realize how big and important Youtube has become,” says Mahaney.
