1. History of Copyright

Wikipedia - The Venetian Patent Statute of March 19, 1474, established in the Republic of Venice the first statutory patent system in Europe, and may be deemed to be the earliest codified patent system in the world.^[1][2] The Statute is written in old Venetian.^[1] It provided that patents might be granted for "any new and ingenious device, not previously made", provided it was useful.^[3] By and large, these principles still remain the basic principles of patent law

Notable copyleft licenses include the GNU General Public License (GPL), originally written by Richard Stallman, which was the first software copyleft license to see extensive use; the Mozilla Public License; the Free Art License; and the Creative Commons ShareAlike license condition – with the last two intended for non-software works, such as documents and pictures, both academic or artistic in nature.^[3] Wikipedia is copyleft under the Creative Commons Attribution-ShareAlike license

According to Creative Commons many people do not regard default copyright as helping them in gaining the exposure and widespread distribution they want. Creative Commons argue that their licences allow entrepreneurs and artists to employ innovative business models rather than all-out copyright to secure a return on their creative investment.

The copyright developed in the USA. They did not in 1886 sign the Berne convention only since 1989. However, since then the USA has turned the tables nad introduced much more exstensive protection for created work. 

Software programs are literally works, by created the vast proprietary software industry where it extracts huge profits year after year.
