At the 2008 Summer Olympics in Beijing, the IOC worked with the local organizing committee to develop a "robust brand-protection program"; logos of non-sponsors were covered with tape on equipment at Games facilities—a restriction that applied even to appliances, bathroom fixtures, elevators, and fire extinguishers. However, there was a high-profile ambush during the opening ceremony; former Olympic gymnast Li Ning, who founded an eponymous Chinese shoe company, lit the Olympic cauldron. The Li-Ning company was not an official sponsor of the Games (but did act as an equipment supplier for some of China's teams), and Li wore Adidas apparel for the sequence per its official sponsorship. On the first trading day following the ceremony, Li-Ning's share price increased by 3.52%.
