The 4-minute video shot by experimental video artist Matthias Fritsch at the Fuckparade on 8 July 2000 begins with the title "Kneecam No. 1" and shows a bare-chested man wearing a Thor's hammer pendant grabbing the arms of and pointing his finger at another man who has just shoved a woman, drinking from a bottle of water offered to him inverted by another man, then dancing down Rosenthaler Straße ( ) to techno music. Fritsch intended it to raise questions of whether the action was real or staged.
Fritsch uploaded the video to the internet in 2001. In 2006 he uploaded it to YouTube, and it went viral in 2007. According to Fritsch, its popularity began on a Latin American pornography site. After being posted on Break.com, it peaked on 28 September at more than 1 million views per day and was watched by over 10 million people over 6 months. More than 700 responses and remixed versions were posted. It was the #1 clip on Rude Tube's series-three episode Drink and Drugs. Mathew Cullen and Weezer wanted to include Techno Viking in their compilation of Internet memes for the "Pork and Beans" music video but were unable to. Techno Viking was also rendered in oils as part of a series on internet memes. By mid-2010, the video had generated over 20 million hits on YouTube alone; as of January 2013[update], the original version had more than 16 million views.
Fritsch mounted an installation and the online Techno Viking Archive "to research the strategies of participatory practice in digital social networks" and presented lectures on the reception of the video. His Music from the Masses project was suggested by the Techno Viking experience: it explores web collaboration by providing silent films for artists to provide soundtracks. In response to legal action by the man featured in the video, access to the Techno Viking video itself has been restricted and annotations on YouTube blocked since late 2009.
The man's name is unknown and Fritsch did not know him. A man who appeared in the 2009 "Bodybuilding" broadcast of the German television show segment Raab in Gefahr was taken to be Techno Viking in a YouTube upload. In 2008, fans claimed MMA fighter Keith Jardine was Techno Viking.
In 2009, his lawyers sent a cease-and-desist letter to Fritsch, who immediately stopped taking payments from YouTube. Three years later, the Technoviking and his lawyer decided to sue Fritsch outright. Fritsch summarized the lawsuit as follows: "I am being accused for creation and publication of images connected to the Technoviking, therefore infringement of personality rights. They also say I am earning a lot of money by that. They argue that [I] gave him the name Technoviking, create 3D characters, comics and more to constantly increase the popularity in order to market Technoviking and therefore cause damage to the protagonist." The court case against Fritsch concerning infringement of personality rights opened in Berlin on 17 January 2013. In June, a decision was reached for the plaintiff and Fritsch was ordered to pay the man €13,000 in damages, almost all he had made from YouTube ads and sales of Techno Viking merchandise, plus €10,000 in court costs, and to cease publication of his image.
Fritsch was put into debt by the decision. He used the occasion to start a crowdfunding campaign to make a documentary about the whole case. The campaign was successful, resulting in the 2015 film The Story of Technoviking.
