The Machine Age is an era that includes the early 20th century, sometimes also including the late 19th century. An approximate dating would be about 1880 to 1945. Considered to be at a peak in the time between the first and second world wars, it forms a late part of the Industrial Age. By the mid to late 1940s, the atom bomb, the first computers, and the transistor came into being, beginning the contemporary era of high technology and thus ending the intellectual model of the machine age founded in the mechanical and heralding a new more complex model of high-technology.
