• MIT community.
•IBM’s Airline Control Program.
• In the 1970s AT&T distributed early
UNIX at no cost to government and
• The advent of Usenet(Newsgroups,
Duke University) in the early 1980s
further connected the programming
community and provided a simpler
way for programmers to share their
software and contribute to software
others had written.
What really Happened ?
In the late 1970s and early 1980s, computer vendors
and software-only companies began routinely
charging for software licenses, marketing it as
"Program Products" and imposing legal restrictions on
new software developments, now seen as assets,
through copyrights ,trademarks, and leasing contracts.
In 1976 Bill Gates signaled the change of the times
when he wrote his now-famous Open Letter to
Hobbyists, sending out the message that what hackers
called "sharing" was, in his words, "stealing". In 1979,
AT&T, for example, began to enforce its restrictive
licences when the company decided it might profit by
selling the Unix system
Y Open Source ?
All software has source code. Open source software grants
every user access to that code. Freedom means choice. Choice
Open source simply creates better software. Everyone
collaborates, the best technology wins. Not just within one
company, but among an Internet-connected, worldwide
community. New ideas and code travel the world in an instant.
