According to Wiki, since the 1968 Winter Olympics in Grenoble, France the Olympic Games have had a mascot. The first major mascot in the Olympic Games was Misha in the 1980 Summer Olympics in Moscow. Misha was used extensively during the opening and closing ceremonies, had a TV animated cartoon and appeared on several merchandise products. Nowadays, most of the merchandise aimed at young people focuses on the mascots, rather than the Olympic flag or organization logos.
Before 1992, most Olympic mascots were created based on an animal unique to the host countries. Since then, human or invented figures have been used, and often more than one mascot – the 1998 Nagano Winter Olympic Games had four mascots; the 2000 Sydney Olympic Games had three and the 2004 Athens Olympic Games had two.
