Copyright vs Copyleft
What is a copyright?
The copyright symbol, or copyright sign, designated by © (a circled capital letter “C”), is the symbol used in copyright notices for works other than sound recordings (which are indicated with the ℗ symbol). The use of the symbol is described in United States copyright law, and, internationally, by the Universal Copyright Convention. The C stands for copyright. Because the © symbol has long been unavailable on typewriters and ASCII-based computer systems, it has been common to approximate this symbol with the characters (C).
What is a copyleft?
Copyleft, designated by (ɔ) (a backwards circled capital letter “C”) is a general method for making a program (or other work) free, and requiring all modified and extended versions of the program to be free as well. Free does not necessarily mean free of cost, but free as in freely available to be modified.
