ZAPPOS.COM SUES WALT DISNEY COMPANY, Inc. has filed a class action lawsuit against the Walt Disney Company over false advertising. Tony Hsieh, CEO of Zappos, says it's just one battle in his efforts to prevent companies from making misleading claims.

The lawsuit alleges that Disneyland's tagline of being "The Happiest Place on Earth" is "clearly false, deceptive, and confusing to the marketplace",and cites internal Net Promoter Score (NPS) metrics that suggest that the designation should be given to, Inc.

A legal representative from Zappos declined to comment, citing company policy on pending litigation. Representatives from Disney did not immediately return phone calls seeking comment.

A local Las Vegas news station uncovered additional details immediately after the actual filing of the lawsuit.
