History of Joomla

Within its first year of release, Joomla was downloaded 2,500,000 times.  Between 2007 and the begining of 2011, it was downloaded more than 21 million times.  There are over 6,000 free and commercial add-ons found on the official Joomla! Extension Directory.

Joomla! was the created from a fork of Mambo in August of 2005.  At that time, the Mambo name was trademarked by Miro International Pvt Ltd. that formed a non-profit organization with the purpose to fund the project and protect it from lawsuits. The Joomla development team claimed that:
  • many of the provisions of the organization's structure went against previous agreements and
  • lacked the necessary consultation with key stake-holders and
  • included provisions that violated core open source values.
