from wiki: In November 16, 2006, 6 months after 'leaving' YouTube, MadV posted the video entitled One World (40 seconds). Audio used is "Með blóðnasir" by Sigur Rós. This video showed the character holding his hand up to the camera, on which he had written in black ink 'One World'. The text of the video is as follows:
"This is an invitation, to make a stand, to make a statement, to make a difference. Join in. Be part of something. Post your response now." This text was followed by the date "4/12/06" (written in European format), meaning the 4th of December 2006. That date was the closing date or due date for all responses.

The 'One World' video was promptly featured on the YouTube front page, and from then on its influence snowballed as YouTube members around the world posted video responses to it, with the same 'ink-on-hand' theme [9]. This represents the largest recorded response to a viral video yet seen on the internet, and has left the video at the number one spot for Most Responded Video of All Time [10] on YouTube.
The influence of silence in this video was picked by MTV, and MadV appeared in an MTV Online news report about the 2008 Presidential candidates [11]. He also appeared on Pepsi's 'The 9 on Yahoo!'
The One World campaign also influenced a new charity website HandMessages.com, where members of the public are invited to continue posting messages written on their hands [12], though it is unclear to what extent MadV himself is involved with this website.
On December 22, 2006 MadV posted 'The Message' (4 minutes 12 seconds), a video compilation of responses to the One World invitation. Audio used is 'Kids Will Be Skeletons' by Mogwai. The video is an emotional sequence of messages collected from YouTube users with the common theme of love and understanding for the whole human race. [13]
