Tuesday at OSCON, the Open Source Initiative (OSI) has continued the celebration of 20 years of open source. A blog post at the OSI reflects on how Open Source fits in with pre-existing intitiatives.
Open source did not emerge from a void. It was consciously a marketing programme for the already-15-year-old idea of free software and arose in the context of both the GNU Project and the BSD community and their history (stretching back to the late 70s). We chose to reflect this in the agenda for our celebration track at OSCON.
But that doesn't mean its inception is irrelevant. The consensus to define open source at the VA Linux meeting and the subsequent formation of OSI and acceptance of the Open Source Definition changed the phrase from descriptive to a term of art accepted globally. It created a movement and a market and consequently spread software freedom far beyond anyone's expectations. That has to be worth celebrating.
Wikipedia's entry on Open Source provides a great deal of information on its origin and application in multiple fields besides just software.

Practical Differences between Free Software and Open Source
In practice, open source stands for criteria a little looser than those of free software. As far as we know, all existing released free software source code would qualify as open source. Nearly all open source software is free software, but there are exceptions. First, some open source licenses are too restrictive, so they do not qualify as free licenses. For example, “Open Watcom” is nonfree because its license does not allow making a modified version and using it privately. Fortunately, few programs use such licenses.
Second, and more important in practice, many products containing computers check signatures on their executable programs to block users from installing different executables; only one privileged company can make executables that can run in the device or can access its full capabilities. We call these devices “tyrants”, and the practice is called “tivoization” after the product (Tivo) where we first saw it. Even if the executable is made from free source code, the users cannot run modified versions of it, so the executable is nonfree.
The criteria for open source do not recognize this issue; they are concerned solely with the licensing of the source code. Thus, these unmodifiable executables, when made from source code such as Linux that is open source and free, are open source but not free. Many Android products contain nonfree tivoized executables of Linux.
