What about Market Day and other events where vendors are on campus?

Market Day is an organized and prescheduled event where vendors make reservations – so the event space will be restricted to the purposes of the event. Commercial speech is speech in which the individual is engaged in commerce, the intended audience is actual or potential consumers (or is commercial), and the content of the message is commercial. Basically, commercial speech is when someone is trying to sell something or otherwise engage in a transaction for some value – the value doesn’t have to be monetary.
