The World Wildlife Fund won a legal battle on Friday to limit the World Wrestling Federation’s use of the initials WWF. A High Court judge in London ruled that the federation broke a 1994 agreement with the enviro group, under which the wrestlers agreed to restrict their use of the initials in promoting their, um, “sport.” In particular, the enviro group says the court victory means the wrestlers will have to stop using www.wwf.com as their website address.
