In February 2005 a small team of developers set out to create an open, free, community-built online resource for all Web developers.
A few months later, on 23 July, 2005 the original Mozilla Developer Network wiki site launched. Since then it has evolved steadily for the convenience and the benefit of its users.
Ten years on and MDN hosts more than 34,500 documents and its global volunteer community is bigger than ever.
Milestones along the way include the development of its own Kuma wiki platform in 2012, and a complete redesign of the front end in 2013.
To celebrate the birthday, Mozilla has produced an infographic showing some facts and figures on how the network is used. Visitors to the network are spread across the world with 26 per cent coming from the USA.
