* Flags: The Globe Theatre would fly a flag when there was a performance scheduled. The flag was usually red and had the theatre's name on it.
* Signs: The theatre would also put up signs announcing the play. These signs would be posted in public places, such as the markets and the city gates.
* Word of mouth: People would also spread the word about upcoming plays by talking to each other. If you knew someone who was going to the theatre, you could ask them for details about the play.
In addition to these methods, the theatre would also use other marketing techniques to promote its plays. For example, they might hire musicians or actors to perform in the streets in order to attract attention. They might also offer discounts or special promotions to encourage people to come to the theatre.
