Open source is slated as the new mode of economy for the new age.
Open source is software which is freely redistributable and can readily be evolved and modified to fit changing needs. The Free Software Foundation founded by Richard M. Stallman supported a great deal of open source development from the early 1980s. Excluding the actual presence of the source code, the software license is the most important part of open source software. There are many such licenses available and in use. Many people find that GPL has a slant towards non profit and has an anti commercial nature.
