"Captain America" was a fictional character designed to take advantage of Steve Rogers' heroic persecution of a Nazi through the streets of New York City. The character was the best propaganda tool in the USA, starring in comic books and war films. When Rogers publicly used the name during his first military action, the adventures of Captain America slowly turned into the fictionalized accounts of Rogers' service on the battlefields of Europe. After the war, the character remained very popular, becoming the main hero of the radio show.
