Microsoft portal application introduced the concept of Web parts — boxes of information on a page that represented a summary or overview of information. (Other vendors referred to these items as "portlets.") By assembling multiple parts on a page, each user could customize his view of the portal to contain the information that pertained to them. In theory, every visitor of the site could have different content at the same URL.
There was also a need for many people to contribute to a single document or worksheet and these people were not necessarily working at the same location. A Web-based solution that allowed shared access to information and documents.

The current version is Microsoft Office SharePoint Server 2007 (MOSS) – It includes the functionality previously included in Microsoft Office SharePoint Portal Server and Microsoft Content Management Server 2002 plus new components like Infopath Form Services and Excel Web Services. This will be integrate with Windows SharePoint Services v3 (WSS v3) which will be freely available as a Windows 2003 server component. WSSv3 is based on the .Net v2 Framework.

In general, SharePoint contains all of the features you would expect from a portal or collaboration tool:

Browser-based customization of page
Browser-based content administration
Aggregation capabilities
Document Repository
Message board
Ad-hoc data storage
E-mail notifications
Announcements, event calendar and contact list.
