Takeshi's Castle
The concept and style of the show has been compared to several Japanese game shows, most notably "Unbeatable Banzuke", "SASUKE" and "Takeshi's Castle". This was brought to the attention of the Japanese broadcaster Tokyo Broadcasting System, who filed a copyright infringement lawsuit against ABC, charging that "Wipeout" is "a blatant copycat" of several of its classic Japanese competition game shows. Among the charges are that ABC bought search terms such as "MXC" (the Americanized comedy version of "Takeshi's Castle") on Google to help drive traffic to the official "Wipeout" page, and that specific obstacles in "Wipeout" were knock-offs of challenges in those Japanese game shows.
