This document provides a history of film posters. It discusses how film posters have been used since the earliest films to promote and advertise movies. Studios produce multiple posters that vary in size and content for different markets. Early posters typically featured illustrations rather than photos and focused on imagery related to the film rather than the actors. Modern posters often highlight the main stars through photographs. Posters are displayed in theaters and public spaces to promote upcoming films and can also be used in advertising through other media like websites and DVD packaging.
