Superman is a fictional superhero, created by the Jewish Jerry Siegel and Joe Shuster, originally appearing in comics, later in radio serials, movies, and television shows.
Although Superman was not the first superhero character, he popularized and influenced the superhero genre. He remains the best selling superhero in comic books of all time and is one of the most lucrative franchises even outside of comic books.
Superman is considered the prototypical superhero. He established the major conventions of the archetype: a selfless, prosocial mission; extraordinary, perhaps superhuman, abilities; a secret identity and codename; and a colorful costume that expresses his nature. Superman's cape and skin-tight suit are widely recognized as a generic superhero costume.
Politically correct aspects including Superman supporting various politically correct causes (varying depending on the time period) and Superman being a politically correct allegory for immigrants, having various problems due to the immigrant background but greatly contributing to society.
