History of the Copyright Statement

Wordpress had a copyright statement from the very beginning and in a changed form until August 25th 2010. It was introduced 2003 by forking the b2 software (cafelog) taking over the original code's copyright notice. Its place was at the end of the read-me (readme.html).

Next to that notice there was no other reference to any copyright regarding the WordPress package within the work. For example, there is no copyright statement inside the code which can make it difficult to find out more about it (an exception are external files which have a copyright notice).

Already in 2003 and 2004, Matt Mullenweg started to remove the original copyright statement and the statement for third party code.

In 2010 the term "Copyright" was completely removed by lead developer Mark Jaquith. It was replaced with the term "License" then.

Finally in 2011 the old copyright statement was restored and put into license.txt together with a new copyright statement which also reflects the 2011 license GPL version change.
