Crazy Frog, originally known as The Annoying Thing, is a computer-animated character created in 2003 by Swedish actor and playwright Erik Wernquist. Marketed by the ringtone provider Jamba! (later known as Jamster), the animation was originally created to accompany a sound effect produced by Daniel Malmedahl in 1997 while attempting to imitate the sound of a two-stroke engine. 　　The Crazy Frog spawned a worldwide hit single with a remix of "Axel F", which reached the number one spot in Turkey, New Zealand, Australia and most of Europe. The subsequent album Crazy Frog Presents Crazy Hits and second single "Popcorn" also enjoyed worldwide chart success, and a second album entitled Crazy Frog Presents More Crazy Hits was released in 2006. The Crazy Frog has also spawned a range of merchandise and toys, and two video games. 　　History 　　In 1997, 17-year-old Gothenburg student Daniel Malmedahl recorded himself imitating the noises produced by a two stroke engine. He posted this on a website and caught the attention of a Swedish television researcher, who convinced Daniel to perform the sound live on air.[1] After it debuted on television, recordings of his performance began appearing on file sharing networks and various websites under the filename "2TAKTARE.MP3" 　　The sound was adopted as the sound of a Formula One car as early as 2001 in the form of "Deng Deng Form" and later "The Insanity Test" both of which were a static background of a Ferrari Formula One car accompanied by the sound. 　　In late 2003, another Swede, Erik Wernquist, encountered the sound effect and, not knowing about the previous incarnations of the sound, was inspired to create the 3D animated character he named "The Annoying Thing" to accompany it.[3] Wernquist worked on the first animation in his spare time using the LightWave 3D modeling application, and the whole process took between 6 and 8 weeks.[3] In October 2003 he posted it on his website and on the CGTalk forum. 　　The animation was a popular attraction at Erik's website, but the sound was credited to "Anonymous". Eventually, word reached Malmedahl that his impressions had been used in a now well-known animation. He contacted Wernquist, apparently giving an impromptu performance to confirm his claims. Wernquist was convinced, and gave credit to Malmedahl for his creation. 　　The animation received attention through filesharing and word of mouth, and when Ringtone Europe and Jamster België (now both merged into Jamba!) got wind of this, realizing the monetary possibilities through capitalizing on the underground cult-status they licensed the rights to the creation, renaming it "Crazy Frog" and starting to market it in mid-2004. 　　In an interview with HitQuarters, Wernquist expressed his displeasure at the choice of name： 　　"If I had known that this was going to be such a big thing I would not have allowed them to use that stupid name. It has nothing to do with the character. It's not a frog and it's not particularly crazy either."
