There have always been many misconceptions surrounding the reason WWE officially changed its name from World Wrestling Federation to World Wrestling Entertainment in 2001. For many this change in name symbolised the transitioning of a new era.
The reality is, the name did unconsciously signify a new era but that wasn't the reason it was changed.
In 1980, Vince McMahon Jr. established the organization Titan Games and credited it the acronym "WWF". This is the place the underlying clash emerged as another association in the U.S was utilizing similar initials.
Overall Store for Nature is an English association that arrangements with protection issues, they try to save untamed life and decrease mankind's biological impression. The philanthropy was established in 1961 and received the initials for a trademark that year.
n 1994, Vince's Titan Sports entered a law-binding agreement with World Wide Fund for Nature that Titan Sports would stop using the WWF acronym in relation to wrestling and would limit its spoken use on live broadcasts.
The charity took Vince McMahon and his company to court and got an injunction approved to take away WWE's rights to the 'WWF' initials. A few months later, the London Court Appeal denied WWE to challenge the injunction put in place in 2001, to give the company rights to the initials in the United States.
Once it was official, the change of name was announced on an episode of Monday Night Raw. The last ever WWE televised event to use the WWF logo was the UK-based pay-per-view Insurrection in 2002.
So, Mr.McMahon company was just forced to changed it's name and logo to WWE.
