This was followed up by another game show, Hvem kan slå Ylvis ( Who can beat Ylvis?) in 2009, based on the German show Schlag den Raab ( Beat Raab). Members of the public were invited to try to beat the brothers at various tasks, with a reward of up to one million Norwegian kroner. In 2010, they hosted Nordens herligste ( The Nordic’s Most Wonderful), a pan-Nordic version of the show. In 2011 they reprised their variety stage show with "Ylvis 4", premiering at the Ole Bull Theater with the entire run sold out before opening night. That year, the brothers also launched a comedy talkshow I kveld med Ylvis ( Tonight with Ylvis) on TVNorge, with Calle Hellevang-Larsen from comedy trio Raske Menn as a sidekick.
Upon being renewed for a second season, the brothers created a production company, Concorde TV, in order to retain rights and creative control of their work. The second series was broadcast in 2012, with David Batra replacing Hellevang-Larsen in the role of sidekick. In the Fall of 2013, Hellevang-Larsen returned for the third series of I kveld med Ylvis. Despite technical difficulties during the broadcast, the first episode took the top ratings spot. Ī number of comedy and parody music videos, either originally featured on I kveld med Ylvis or used to promote the show, have been released onto YouTube and other streaming media. " The Fox" and "Stonehenge" have also been released as singles. "The Fox", produced by StarGate and M4SONIC, which was released on 3 September 2013 to promote the upcoming third series of I kveld med Ylvis, went viral on YouTube and received 31 million views in its first two weeks. It was the most watched video on YouTube worldwide in 2013, and as of August 2021, the video has over 1 billion views.
