On the flip side:
In 1997, Welles started an online business selling pictures of herself. On her website, she described herself as a former Playboy model and Playmate of the Year. Playboy Enterprises, which was starting up its own online business at this time, sued Welles in 1998, claiming that it had the exclusive right to use of its trademark terms "Playboy" and "Playmate of the Year" for commercial purposes. The outcome of the suit, Playboy Enterprises, Inc. v. Welles[1], was that virtually all of Welles' uses of the terms were considered nominative uses, and did not infringe.
