Web portal

A web portal is a web site that provides a gateway, or portal, to other resources on the Internet. Open Directory requires that sites listed as a "portal" contain these features:

• Search Engine/Directory
• E-Mail Accounts
• News
• Sports and Weather

'Mega' Web Portals provide a broad range of features, services, content and commercial partnerships. Examples include: http://yahoo.com and http://my.netscape.com

'Vertical', or 'Niche', Web Portals focus on a specialized audience and/or topic, and provide features like search engines, discussions, and directories. Examples include:

• http://searchbug.com
• http://hindustanlink.com
• http://inlet.org

In the late 1990s, the web portal was a hot commodity. After the rapid diffusion of web browsers in the mid 1990s, many companies tried to build or acquire a portal, in order to have a piece of Internet market. Web portal gained a special attention because it was, for many users, the starting point of their web browser. Netscape Netcenter[?] became a part of America Online, the Walt Disney Company launched Go.com[?], and Excite[?] became a part of AT&T during the late 1990s. Lycos was said to be a good target for other media companies such as CBS.

Many of the portals started initially as either Internet directories (notably Yahoo!) and/or search engines (Excite, Lycos, Altavista[?], infoseek, and hotbot, among the old ones). The expansion of service provision occurred as a strategy to secure the user-base and lengthen the time a user stays on the portal. Services which require user registrations such as free email, customization features, chatrooms were considered to enhance repeat use of the portal. Game, chat, email, news, and other services also tend to make users' stay longer, thereby increase the advertisement revenue.

In the early 2000s, a major industry shift in web portal focus has been the corporate intranet portal, or "enterprise web". Where expecting millions of unaffiliated users to return to a public web portal has been something of a mediocre financial success, using a private web portal to unite the web communications and thinking inside a large corporation has begun to be seen by many as both a labor-saving and a money-saving technology. Some corporate analysts have predicted that corporate intranet web portal spending will be one of the top 5 areas for growth in the internet technologies sector during the first decade of the 21st century.

The widely recognized market-share leader in intranet web portal software is Plumtree Software (http://www.plumtree.com/). Other corporate portal vendors include IBM Corporation, Microsoft, Oracle, and SAP (http://www.sap.com/).
