"Google says the vast majority of the 1 million businesses that use Google Apps opt for the free advertising supported version.

Google Apps is a suite of online applications like gmail, Google calendar, Google Docs, etc. that are packaged and tailored for business use. It's growing fast - in a recent post where Google announced the opening of a reseller program, the company said that more than 1 million businesses and 10 million users use Google Apps today, and 3,000 new businesses sign up daily. The largest business user, Genentech, has 20,000 employees on Google Apps."
