"SUPERMAN was introduced to the world in 1938 as the Champion of the Oppressed. In time his moniker morphed into the defender of Truth, Justice, and the American Way. In his journey through comic books, comic strips, radio and TV programs, movies, and more, the character has kept a careful watch over the less fortunate and the downtrodden. From defending coal miners against unsafe working conditions (1938) to supporting protestors opposing the oppressive regime in Iran (2011), Superman has maintained a social conscience that is as strong as steel."
