In the United States, ticket resale is a $5 billion industry. Ticket resale on the premises of the event (including adjacent parking lots that are officially part of the facility) may be prohibited by law. These laws vary from state to state, and the majority of US states do not have laws in place to limit the value placed on the resale amount of event tickets or where and how these tickets should be sold. Ticket re-sellers may conduct business on nearby sidewalks, or advertise through newspaper ads or ticket brokers.
