They sought to bring a higher profile to the practical benefits of freely available source code, and they wanted to bring major software businesses and other high-tech industries into open source.
Perens attempted to register "open source" as a service mark for the OSI, but that attempt was impractical by trademark standards.
There has been a significant shift in the corporate philosophy concerning the development of FOSS. In 1998, a group of individuals advocated that the term free software should be replaced by open-source software (OSS) as an expression which is less ambiguous Software developers may want to publish their software with an open-source license, so that anybody may also develop the same software or understand its internal functioning.
With open-source software, generally anyone is allowed to create modifications of it, port it to new operating systems and instruction set architectures, share it with others or, in some cases, market it.
Software licenses grant rights to users which would otherwise be reserved by copyright law to the copyright holder.
The new term they chose was "open source", which was soon adopted by Bruce Perens, publisher Tim O'Reilly, Linus Torvalds, and others.
The Open Source Initiative was founded in February 1998 to encourage use of the new term and evangelize open-source principles.
The open source label came out of a strategy session held on April 7, 1998 in Palo Alto in reaction to Netscape's January 1998 announcement of a source code release for Navigator (as Mozilla).
A group of individuals at the session included Tim O'Reilly, Linus Torvalds, Tom Paquin, Jamie Zawinski, Larry Wall, Brian Behlendorf, Sameer Parekh, Eric Allman, Greg Olson, Paul Vixie, John Ousterhout, Guido van Rossum, Philip Zimmermann, John Gilmore and Eric S. They used the opportunity before the release of Navigator's source code to clarify a potential confusion caused by the ambiguity of the word "free" in English.
