The Machine Age is an era that includes the early-to-mid 20th century, sometimes also including the late 19th century. An approximate dating would be about 1880 to 1945. Considered to be at its peak in the time between the first and second world wars, the Machine Age overlaps with the late part of the Second Industrial Revolution (which ended around 1914 at the start of World War I) and continues beyond it until 1945 at the end of World War II. The 1940s saw the beginning of the Atomic Age, where modern physics saw new applications such as the atomic bomb, the first computers, and the transistor. The Digital Revolution ended the intellectual model of the machine age founded in the mechanical and heralding a new more complex model of high technology. The digital era has been called the Second Machine Age, with its increased focus on machines that do mental tasks.

Artifacts of the Machine Age include:
- Reciprocating steam engine replaced by gas turbines, internal combustion engines and electric motors
- Electrification based on large hydroelectric and thermal electric power production plants and distribution systems
- Mass production of high-volume goods on moving assembly lines, particularly of the automobile
- Gigantic production machinery, especially for producing and working metal, such as steel rolling mills, bridge component fabrication, and automobile body presses
- Powerful earthmoving equipment
- Steel framed buildings of great height (the skyscraper)
- Radio and phonograph technology
- High speed printing presses, enabling the production of low cost newspapers and mass market magazines
- Low cost appliances for the mass market that employ fractional horsepower electric motors, such as the vacuum cleaner and the washing machine
- Fast and comfortable long distance travel by railroad, automobile, and aircraft
- Development and employment of modern war machines such as tanks, aircraft, submarines and the modern battleship
- Streamline designs in automobiles and trains, influenced by aircraft design
- Exploitation of natural resources with little concern for the ecological consequences; a continuation of 19th century practices but at a larger scale.
- Release of synthetic dyes, artificial flavorings, and toxic materials into the consumption stream without testing for adverse health effects.
- Rise of petroleum as a strategic resource
- Conflicts between nations regarding access to energy sources (particularly oil) and material resources (particularly iron and various metals with which it is alloyed) required to ensure national self-sufficiency. Such conflicts were contributory to two devastating world wars.
- Climax of New Imperialism and beginning of decolonization
