For nonprofits and government agencies, PSAs offer a win-win PR situation with free media placement and visibility in a paid media environment. And on occasion, they can
literally inspire the nation. In the 1940s, the public service campaign featuring "Rosie the Riveter" inspired women with a patriotic message to join the workforce during the
Second World War. This campaign wound up increasing the number of women employed in factories by 20% and still remains today as a feminist icon.
