 Under the agreement, Titan had agreed to cease using the written acronym "WWF" in connection with its wrestling promotion, and to minimize (though not eliminate) spoken uses of "WWF" on its broadcasts, particularly in scripted comments.In exchange, the environmental group (and its national affiliates) agreed to drop any pending litigation against Titan, and agreed not to challenge Titan's use of the full "World Wrestling Federation" name or the promotion's then-current logo.In 2000, the World Wide Fund for Nature sued World Wrestling Federation Entertainment Inc. in the United Kingdom, alleging various violations of the 1994 agreement.
