The Federal Trade Commission (FTC) has closed an investigation of UFC regarding whether "Zuffa, LLC, or any other unnamed persons, partnerships, or corporations have engaged or are engaging in conduct that violates Section 5 of the Federal Trade Commission Act," which holds that "unfair or deceptive acts or practices in or affecting commerce...are...declared unlawful." The Las Vegas Review-Journal was the first to report the story.
This is the second investigation the FTC has conducted regarding the UFC's business practices. The first was held in 2012 and looked into the UFC's acquisition of Strikeforce. Like this most recent investigation, that, too, was closed without any further action being taken.
