Bronze Age

The Silver Age of Comics was a historical period in the publication of DC comic books, including those of the Superman franchise. This age is characterized by "campy" storylines, and major expansion of the Superman mythos. Characters such as Supergirl, Krypto, Streaky, and the Legion of Super-Heroes, among others, were added to the Superman mythos during this era.

There's no clear beginning of this era, as stories followed continuously after the previous era, the Golden Age. In retrospect, however, the stories were retconned so that all stories from the Golden Age took place in a separate universe from those of the Silver Age. Golden Age stories became Earth-Two and Silver Age stories took place in Earth-One.

The silver age did, however, have a clear end: the storyline Crisis on Infinite Earths erased all existing DC continuities and merged elements of them into one consistent universe, called New Earth. This occurred in 1985, and led to the beginning of the Modern Age.
