Oracle PowerBrowser was a web browser created in 1996 by Oracle Corporation. It featured a multiple document interface and offered the possibility to act as a web server allowing users to host webpages on their computers. It pre-dated CSS and scripting, and was quickly discontinued.
The original Powerbrowser was built by 3 people, Jon McCormack, Rhys Weatherly and Todd Werelius. They built the first iteration in 90 days as proof of concept for a number of ideas (personal publishing, extensible component architecture etc.)
The team was under the direction of Marc Benioff before he left Oracle and founded Salesforce.com
