People interested in open source:
The Open Source movement came after the Free Software movement. Both are based on the idea that programmers should be able to see the code and modify it.
What happens to the modifications depends on which of the Open Source Licenses applies. Stricter licenses such as the Gnu GPL require modifications to be put back in the main code stream. Less restrictive licenses such as the Apache Community License require only that subsequent users attribute the software to Apache.
There are many uses of Open Source in Business.
