History Of The Open Source Initiative

Development based on the sharing and collaborative improvement of software source code has a history essentially as long as software development itself. In the late 1990s, interest and participation in this phenomenon increased markedly with mainstream recognition of Linux in publications like Forbes and the release of the Netscape browser’s source code. OSI was formed in 1998 as an educational, advocacy, and stewardship organization at this important moment in the history of collaborative development. The “open source” label was created at a strategy session held on February 3rd, 1998 in Palo Alto, California, shortly after the announcement of the release of the Netscape source code. The strategy session grew from a realization that the attention around the Netscape announcement had created an opportunity to educate and advocate for the superiority of an open development process. The conferees believed the pragmatic, business-case grounds that had motivated Netscape to release their code illustrated a valuable way to engage with potential software users and developers, and convince them to create and improve...

Two of those present at the Palo Alto meeting (Eric Raymond and Michael Tiemann) would later serve as presidents of OSI, and other attendees (including Todd Andersen, Jon “maddog” Hall, Larry Augustin, and Sam... The open source movement has fundamentally transformed the software industry by promoting collaboration, transparency, and freedom in software development. From its early roots in academic and hacker culture to the creation of foundational projects and organizations, open source has reshaped how software is built, shared, and commercialized. This blogpost presents a detailed timeline of the open source movement from its inception to the conception of the Open Source Science (OS-SCi) in 2022, highlighting key milestones, pivotal figures, and major projects that... The open source movement’s roots lie in the 1950s when software was freely exchanged among researchers and academics.

Institutions like MIT fostered a culture of openness and experimentation, with groups such as the Tech Model Railroad Club pioneering the hacker ethos. The PDP-1 minicomputer at MIT in 1961 became a focal point for early hackers who explored computing’s potential through playful innovation. This culture valued sharing, modification, and collaborative improvement of software, setting the stage for the open source philosophy1. The late 1970s and early 1980s saw a shift toward proprietary software as legal decisions granted software copyright protection, enabling commercial licensing models. In response, Richard Stallman launched the GNU Project in 1983 to create a free operating system and founded the Free Software Foundation in 1985. The GNU Manifesto articulated the moral and practical imperatives of software freedom, advocating for users’ rights to study, modify, and distribute software.

This period marked the formalization of the free software movement, which laid the ideological and legal groundwork for open source1. The term “open source” was popularized in 1998 at a summit organized by Tim O’Reilly and supported by key figures including Linus Torvalds. The Open Source Initiative (OSI) was founded to promote open source software pragmatically, focusing on licensing and community collaboration. This decade also saw the rise of major open source projects such as the Linux kernel (1991), the Apache HTTP Server (1995), and the Mozilla browser (1998). These projects demonstrated the viability of open source as a development model and began to challenge proprietary software’s dominance1. The late 1990s and early 2000s marked the professionalization of open source with the IPOs of companies like Red Hat and VA Linux, which commercialized Linux distributions.

The Apache Software Foundation (ASF) was incorporated in 1999 to support the growing ecosystem of open source projects. Mozilla Firefox’s release in 2004 further expanded open source’s reach into web browsing, emphasizing privacy and security. These developments showcased open source’s economic potential and its ability to support sustainable business models1. The Open Source Initiative (OSI) is a California public benefit corporation "actively involved in Open Source community-building, education, and public advocacy to promote awareness and the importance of non-proprietary software".[4] The OSI is a California public-benefit nonprofit corporation, with 501(c)(3) tax-exempt status.[5] The organization is professionally overseen by an Executive Director and staff, and supported by its Board of Directors responsible for overseeing duty... The Open Source Definition is a derivative document based on the Debian Free Software Guidelines (DFSG), released in 1997 by Bruce Perens.

As Debian Project Leader, Perens released the scribed DFSG on July 4, 1997. In an announce post, Perens states he hopes other distributions use the DFSG as a model and states "We hope that other software projects, including other Linux distributions, will use this document as a...

Any organization can use the Debian Free Software guidelines by citing the Social Contract. No open source definition required.

Perens modified the Debian Free Software Guidelines into the Open Source Definition by removing Debian references and replacing these with "Open Source". The original announcement of The Open Source Definition happened on February 9, 1998, on Slashdot[6] and elsewhere; the definition was given in Linux Gazette on February 10, 1998.[7] The free software movement was started by Richard Stallman 35 years ago. OSI cofounder Bruce Perens explains that “open source is the proper name of a campaign to promote the pre-existing concept of free software to business, and to certify licenses to a rule set.” In 1998, Netscape cut Netscape Navigator adrift rather than hosting open development itself, leading to the Mozilla project. It became clear that many businesses would adopt free software if only there was an objective rather than an ideological approach to it.

The term “open source” was first applied to software at a strategy session held at the VA Linux Systems offices on February 3, 1998, in Mountain View, California. The term “open source” itself was coined by Christine Peterson, president of the Foresight Institute, a think tank focused on nanotechnology. The Open Source Initiative (OSI) was founded as steward of the newly coined “open source” term in late February 1998, with Eric Raymond as its first president, Bruce Perens as vice president, and an... The OSI logo, which alludes to both the letter O of “open” and to a keyhole for unlocking source code, was created by Colin Viebrock. In 1999, Bruce Perens, the author of the Debian Free Software Guidelines, adapted them into an objective definition of how a software license can be identified as open source—the Open Source Definition (OSD). In the 1980s software used to be shared via BBS systems and it was common for source code to be distributed freely, it encouraged hacker culture which is the basis of free and open...

NDAs and proprietary software licenses became the norms, Richard Stallman saw this culture threatened, and advocated that software should not have owners. Then he decided to create a complete operating system that would not deprive users of the freedom to understand how it worked, and would allow them to make changes if they wished. so he launched the GNU Project in 1983,which spurred the free software movement, and is the basis for the open source movement. It is thanks to this groundwork that "open source" and its accompanying principles were established in 1998.The goal of the GNU project was to clone the Unix operating system to create a system that... In January 1984 he created the first compiler system the GCC. Then in Early in 1985, he published "The GNU Manifesto," which was a call to arms for programmers to join the effort, and launched the Free Software Foundation in order to accept donations to...

This document is the founding charter of the free software movement. Until 1989, software written and released by the Free Software Foundation and RMS did not have a single license however, after a company called Unipress forced Stallman to stop distributing copies of an Emacs... Then first version of the GNU General Public License was released in 1989, which encapsulated the values of copyleft(not copyright). You may use, copy, distribute, and modify the software covered by the license, but if you make changes, you must share the modified source code alongside the modified binaries. This simple requirement is what enabled the decentralized, collaborative development model of the free software movement to flourish. In the early 1990s the free software community received the first complete free operating system with Linus Torvald’s kernel combined to GNU operating system.

Debian, founded by Ian Murdock in 1993, committed to the GNU and FSF principles of free software. Linux adoption by businesses and governments began in the late 1990s. Website-based companies emerged and made extensive use of free web servers, especially the Apache HTTP Server. The LAMP (Linux, Apache, MySQL, PHP) stack gained popularity over expensive proprietary solutions. The Open Source Initiative (OSI) is an organization dedicated to promoting open source software. The organization was founded in February 1998, by Bruce Perens and Eric S.

Raymond, prompted by Netscape Communications Corporation publishing the source code for its flagship Netscape Communicator product. Later, in August 1998 the organization added a board of directors. Raymond was president from its founding until February 2005. The current president is Michael Tiemann. Although born from the same history of Unix, Internet free software, and the hacker culture as the free software movement launched by Richard Stallman and his Free Software Foundation, the Open Source Initiative was... Stallman counter-charges that OSI's pragmatic focus on a model for software development and marketing ignores what he considers to be the central "ethical imperative" and the focus on "freedom" that underlies free software, as...

Nevertheless, he describes his free software movement and the Open Source Initiative as separate camps within the same free software community. According to Stallman, "We disagree with the open source camp on the basic goals and values, but their views and ours lead in many cases to the same practical behavior—such as developing free software. As a result, people from the free software movement and the open source camp often work together on practical projects such as software development."[2] Open source software has become an integral part of technology and the internet today. From web servers to mobile operating systems, open source powers much of the digital world. But open source is more than just free access to code – it represents a movement centered around collaboration and democratization of software.

In this post, we‘ll explore the origins of open source software and the ideals behind the movement. We‘ll learn how it evolved from a rebellion against proprietary software into a mainstream model embraced even by large tech companies. Before diving into the history, let‘s clarify what open source software actually means. Open source software has source code that is publicly accessible for anyone to inspect, modify, and enhance. The code is often developed collaboratively and licensed in a way that allows for free distribution and adaptation. This approach contrasts with proprietary or closed source software that only provides the executable files without the underlying source code.

The Open Source Initiative (OSI) defines key aspects like free redistribution, access to source code, allowing modifications and derived works, permitting commercial use, non-discrimination against persons or groups, and non-contamination from proprietary software. Open source licenses like the GPL allow software to remain open for community contribution.
