Google Apps is a collection of online applications used to bring multiple tasks together in one place. Initially created as Gmail For Your Domain in February 2006, it expanded as Google Apps For Your Domain in August 2006.

Google Apps are accessible wherever there is an Internet connection and utilize a variety of individual Google products. These include Google Docs, Google Talk, Google Calendar and Gmail. A custom domain name can be used to connect your personal or corporate web site's email address to Gmail, creating addresses @yourdomain.com instead of @gmail.com. A free version of the product is available, as well as a pay service for $50 per user account per year.
