(Reuters) - A wine fair in southwest Germany has been ordered to stop using the Olympic name and a similar logo or face a hefty fine, with the German Olympic Committee accusing it of ambush marketing. The community of Langenlonsheim used the Olympic symbols, including a seven-ring logo as opposed to the five rings of the Games, for a local wine fair which it called the "wine Olympics" in August around the time of the 2012 London Games.
