A Biden administration ban on so-called "junk fees" took effect Monday. In response, Ticketmaster said it will start displaying the full price of a ticket as soon as U.S. consumers begin shopping. Ticketmaster, long a subject of complaints about its hidden fees, was among those targeted by the new rule, which was announced in December by the Federal Trade Commission. The rule requires ticket sellers, hotels and others to disclose processing fees, cleaning fees and other charges up front. Ticketmaster said it will also tell shoppers where they are in line when they log in to buy tickets to an event.

The Justice Department has sued Ticketmaster and parent company Live Nation Entertainment, accusing them in a sweeping antitrust lawsuit of running an illegal monopoly over live events in America that squelches competition and drives up prices for fans. Filed in federal court in Manhattan, the complaint was brought by 30 state and district attorneys general. It seeks to break up the monopoly they say is squeezing out smaller promoters, hurting artists and drowning ticket buyers in fees. The company has a long history of clashes with major artists and their fans, including Taylor Swift and Bruce Springsteen.
