History of the OSI
The prehistory of the Open Source Initiative includes the entire history
of Unix, Internet free software, and the hacker culture.
The "open source" label itself came out of a strategy session
held on February 3rd 1998 in Palo Alto, California. The people
present included Todd Anderson, Chris Peterson (of the Foresight Institute), John
"maddog" Hall and Larry Augustin (both of Linux International), Sam Ockman (of the
Silicon Valley Linux User's Group), and Eric Raymond.
We were reacting to Netscape's
announcement that it planned to give away the source of its
browser. One of us (Raymond)
had been invited out by Netscape to help them plan the release and
followon actions. We realized that the Netscape announcement had created a
precious window of time within which we might finally be able to get
the corporate world to listen to what we have to teach about the
superiority of an open development process.
We realized it was time to dump the confrontational attitude that has
been associated with "free software" in the past and sell the idea strictly
on the same pragmatic, business-case grounds that motivated Netscape.
We brainstormed about tactics and a new label. "Open source,"
contributed by Chris Peterson, was the best thing we came up with.
Over the next week we worked on spreading the word. Linus Torvalds
gave us an all-important imprimatur :-) the following day. Bruce
Perens got involved early, offering to trademark "open source" and
host this web site. Phil Hughes offered us a pulpit in Linux Journal. Richard Stallman
flirted with adopting the term, then changed his mind.
The Open Source Definition is derived from the Debian
Free Software Guidelines. Bruce Perens composed the original
draft; it was refined using suggestions of the Debian GNU/Linux Distribution
developers in e-mail conference during most of June, 1997. They then
voted to approve it as Debian's publicly stated policy. It was revised
somewhat and Debian-specific references were removed at the
origination of the Open Source Initiative in February 1998.
The Open Source Initiative is now a California public benefit
(not-for-profit) corporation whose official address (to which you should
feel free to send tax-deductible contributions) is:

announces it will release the source code for Navigator.
- 3 Feb 1998:
- Palo Alto brainstorming session coins the term "open
source." During the following week, Bruce Perens and ESR launch
- Early February:
- Spirited debate within the hacker community: "open source" vs.
"free software". This terminological debate is understood by all
parties to be a proxy for wider issues about the community's
relationship to the business world. Meanwhile, the term begins to
show up in trade-press articles relating to Linux and the upcoming
- 23 Feb 1998:
February 23 press release referred to "open source", and the same
day O'Reilly associates agreed to use the term in their press releases
and on their web page.
- 31 Mar 1998:
- Navigator source is released. Within hours, fixes and
enhancements begin pouring in off the net.
- 7 Apr 1998:
- Tim O'Reilly's "Freeware Summit Conference" brings together 18
of the movement's leaders. The term "open source" and accompanying
economics- and self-interest-based arguments are endorsed by a vote.
- 14 April 1998:
- Salon magazine
interviews ESR on open source. The message is starting to get out to the
mainstream (non-technical) press.
- April 1998:
- References to "open source" begin to fly thick and fast in the
trade press, with positive spin (see the graph
below). Within the hacker community itself the terminological (and
underlying ideological) debate winds down, with "open source" emerging
as a clear majority choice. Use of the term "free software" begins a
- 7 May 1998:
- Corel Computer Corporation announces
the Netwinder, an inexpensive network computer that uses Linux as its
production OS. This is the first major, conscious adoption of the
frosting model by an established business.
- 11 May 1998:
- Corel, parent company of Corel Computer Corporation and publisher of
Word Perfect, announces plans to port WordPerfect and its other office
software to Linux.

- Sun Microsystems and Adaptec join Linux International the first
two large established OS and hardware vendors to do so.
- 22 Jun 1998:
- IBM announces
that it will sell and support Apache
as part of its WebSphere suite. The trade press hails this as a
breakthrough for open-source software.
- 10 July 1998:
- The Economist takes editorial
notice of Linux, reporting Datapro's positive
findings. The message is beginning to get out in the financial press.

- Computerworld, perhaps the
most influential of today's MIS magazines, publishes an
interview with ESR on open source.
- 17 July 1998:
- Oracle and Informix announce that they will port their databases
to Linux. (This follows similar, lower-profile announcements from
Computer Associates and Interbase.)
- August 1998:
- The Forbes magazine issue with

- 24 Aug 1998:

UnixWare 7 Linux-binary-compatible. This
means a proprietary Unix vendor has judged the leading open-source OS
a significant source of native applications!

we're worried." about Apache and Linux and says Microsoft is

Eric Rauch has done Lexis-Nexis searches to track
the number of references to "open source" (coupled with "netscape",
"software", or "linux" to avoid false hits) in American newspapers and
magazines. You can see his plot, which
shows a steady rise from zero in January 1998 (with a spike in April
doubtless due to the April 1 Netscape release).
(Unfortunately, Lexis/Nexis rearranged its libraries in August 1999, so
later figures won't be comparable to those above.)
