Google's first big advertising push for the service was called "Going Google" and was advertised offline in the form of billboards along some major highways in the U.S. including the 101 in San Francisco, West Side Highway in New York, The Ike in Chicago and the Mass Pike in Boston. Google announced today that it is now set to roll its "Going Google" advertising campaign out in a much larger way.

The search giant will run full-page ads in the New York Times, The Economist, Business Week, Forbes, and Fortune. Ads will also be run online on the Wall Street Journal, CNN Money, Bloomberg, and Fortune. The ads will talk about companies that have changed to Google's suite of email and productivity apps from those offered by IBM, Microsoft, and other companies.

Google's Tom Oliveri told eWeek, "These are all places where business decision makers and IT decision makers spend time. We want to help them understand the benefits of the cloud."

In addition to running new ads online and in print, Google will also offer up more ads in public locations on billboards on highways and in train stations in other countries. Google will advertise in London, Paris, Sydney, Australia, Tokyo, and Singapore.

Reuters reports that Google's Apps are now in use by 2 million businesses which is up from 1.75 million that were using them in June. That number includes large enterprise users who pay $50 per year per user to get access to the cloud-based apps. Reuters also reports that Apps are a highly profitable business for Google generating hundreds of millions in profits each year.
