Wikipedia founder Jimmy Wales denies political muscle

2 August 2012 Last updated at 21:44 BST

Since October the website Wikipedia has deliberately taken itself off screens in protest against what it sees as infringements of the freedom of speech on the internet - in Italy, the US and only a few weeks ago in Russia. In the US it caused legislation to be shelved.

It has become a powerful animal - some believe it may become a political one too.

The BBC spoke to Jimmy Wales, the co-founder of the site, discussing what the criteria had become for this community to exercise its increasing muscle.
