History

In February 2006, Google created Gmail For Your Domain with an invitation-only beta, which allowed Gmail to be used with a custom domain name. It featured 2GB of e-mail storage, and many of the standard Gmail features.

In August 2006, Google expanded on this service and developed Google Apps For Your Domain, incorporating more recent Google services, including Google Calendar, Google Talk, and Google Page Creator. Later, Google added a "Start Page" to all accounts, which is based on their Personalized Homepage (google.com/ig) service.

In October 2006, Google allowed educational institutions to sign-up for the service as well, which was retitled Google Apps For Education. A large implementation of Google Apps is at Lakehead University in Ontario, Canada, where 38,000 users have Gmail and in-browser IM capabilities.

On 22 February 2007, Google launched a Premier Edition for enterprise, as well as making registration public for all Google Apps services. At the same time, all products were unified, and the online control panel was redesigned.

In June 2007, email migration from IMAP email services was added to Google Apps.
