Germany developed an extensive propaganda campaign during world war ii to build support for its war effort. t/f

The question is asking whether it is true that Germany developed an extensive propaganda campaign during World War II to build support for its war effort. This is true. Germany made propaganda posters, played propaganda in the Radio and made propaganda movies. Especially famous was Leni Riefenstahl who made good-quality propaganda movies - they are appreciated for their art but are controversial for the role they played in the war.

Ihave no idea but for the points!
