Google announced the launch of Google Sites, a program used for collaboration among teams of workers. This new offering from Google Apps will help to create a team site that brings together all the information a team needs to share, including docs, videos, photos, calendars and attachments.

The Google Sites service is based on a technology from a start-up called JotSpot that was acquired in October 2006. Like other elements of Google Apps, the service will be free and require no installation, maintenance or upgrades.

This new free service from Google is seen as a challenge to Microsoft Corp.’s SharePoint service that is charging a licensing fee.
