The Atomic Age, also known as the Atomic Era, is a phrase typically used to delineate the period of history following the detonation of the first nuclear bomb.

The Atomic Age in the 1950s

The phrase stems from the feeling of nuclear optimism in the 1950s in which it was believed that all power generators in the future would be atomic in nature. The atomic bomb would render all conventional explosives obsolete and nuclear power plants would do the same for power sources such as coal and oil. There was a general feeling that everything would use a nuclear power source of some sort, in a positive and productive way, from irradiating food to preserve it, to the development of nuclear medicine. This would render the Atomic Age as significant a step in technological progress as the first smelting of Bronze, of Iron, or the commencement of the Industrial Revolution.

This included even cars, leading Ford to display the Ford Nucleon concept car to the public in 1958.
