The entertainment industry during World War II underwent changes to help aid the cause of the war. The entertainment industry during this time was often controlled by a country's government. Since the governments believed that a supportive home front was crucial to their countries' victory, they generally sought to keep the civilian spirits high and to depict the war in a positive light. With this motive in mind, governments engaged in the regulation and censorship of the forms of media, as well as the introduction of new methods of informing citizens through these media outlets.
