Assessment

Historical records, primary source archives, and encyclopedic documentation confirm that WordPress originated in 2003 as a fork of b2/cafelog (often referred to simply as b2). Michel Valdrighi created b2/cafelog in 2001 as an open-source GPL-licensed blogging engine, but active development stalled in late 2002. In January 2003, Matt Mullenweg and Mike Little organized to fork the inactive codebase, officially releasing WordPress 0.70 as a direct fork and successor on May 27, 2003.

Michel Valdrighi released the open-source GPL-licensed b2/cafelog blogging software in 2001 and ceased regular updates in late 2002.
