History of Open source

     The concept of open source and free sharing of technological information existed long before computers. For example, cooking recips  have been shared since the beginning of human culture. Open source can pertain to businesses and to computers, software and technology.

        The free sofware movement was launched in 1983. In 1998, a group of individuals advocated that the term free sofftware should be replaced by open source software (OSS) as an expression which is less ambiguous and more comfortable for the corporate world^.Software developers may want to publish their software with an open software license, so that anybody may also develop the same software or understand its internal functioning. Open source software generally allows anyone to create modifications of the software, port it to new operating systems and processor architectures, share it with others or, in some cases, market it. Scholars Casson and Ryan have pointed out several policy-based reasons for adoption of open source, in particular, the heightened value proposition from open source (when compared to most proprietary formats) in the following categories:

• Security
• Affordability
• Transparency
• Perpetuity
• Interoperability
• Localisation.

Particularly in the context of local governments (who make software decisions), Casson and Ryan argue that "governments have an inherent responsibility and fiduciary duty to taxpayers" which includes the careful analysis of these factors when deciding to purchase proprietary software or implement an open-source option.

The Open Source Definiton, notably, presents an open source philosophy, and further defines the terms of usage, modification and redistribution of open source software. Sofgrant rights to users which would otherwise be reserved by copyright law to the copyright holder. Several open source software licenses have qualified within the boundaries of the Open Source Definition. The most prominent and popular example is the GNU General Public License (GPL), which “allows free distribution under the condition that further developments and applications are put under the same licence” – thus also free. While open source distribution presents a way to make the source code of a product publicly accessible, the open source licenses allow the authors to fine tune such access.

The open source label came out of a strategy session held on April 7, 1998 in Palo Alto in reaction to Netscape January 1998 announcement of a source code release for Navigator (as Mozilla). A group of individuals at the session included, , Tom Paquin, Greg Olson,  and. 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.

Many people claimed that the birth of, since 1969, started the open source movement, while others do not distinguish between open source and free software movements.

The  (FSF), started in 1985, intended the word "free" to mean freedom to distribute (or "free as in free speech") and not freedom from cost (or "free as in free beer"). Since a great deal of free software already was (and still is) free of charge, such free software became associated with zero cost, which seemed anti-commercial.

The  (OSI) was formed in February 1998 by Eric S. Raymond and. With at least 20 years of evidence from case histories of closed software development versus open development already provided by the Internet developer community, the OSI presented the 'open source' case to commercial businesses, like Netscape. The OSI hoped that the usage of the label "open source," a term suggested by Peterson of the  at the strategy session, would eliminate ambiguity, particularly for individuals who perceive "free software" as anti-commercial. 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  for the OSI, but that attempt was impractical by  standards. Meanwhile, due to the presentation of Raymond's paper to the upper management at Netscape—Raymond only discovered when he read the, and was called by Netscape CEO Jim Barksdale's PA later in the day—Netscape released its Navigator source code as open source, with favorable results.
