The Office of War Information was created during World War II and its main purpose was to deliver information and propaganda about the war easily in order for more American civilians to join the war effort.
This was very important during this time as people were needed in order for the United States to exceed in the war. World War II was costly, not only with money, but with lives and other needed goods. The United States government thought it was important to send out propaganda so people would feel a sense of patriotism for their country and help out with the effort.
A lot of this propaganda included radio shows, flyers, films, posters, pictures, newspapers, milk cartons, and other things that American citizens saw and used everyday. One of the most famous ones was the posters of Uncle Sam, saying "Uncle Sam wants you!", this attracted a lot of people to the war effort.
Not only were men needed to battle in the war, women were needed to help in factories at the time and to create much needed goods for soldiers.
