Armonk, N.Y.--IBM Corp. has released software designed to handle burgeoning corporate Web sites. Called IBM Content Manager, the new product allows companies to identify, sort and store all kinds of information in a single archive. That includes corporate documents, e-mails, streamed audio and video, and digital photo images. The software also makes it possible for managers to make that content available to various business applications. In launching the product, which is priced at $15,000 per server, IBM enters a market that's expected to grow to $10 billion by 2004, according to the research firm Meta Group. IBM said the advent of the Internet, intranets and extranets means that corporate data doubles every eight months. Competitors in this arena include high-flying Broadvision Inc., which has long provided applications for managing information across big corporations.
