After the war, the company concentrated on making its typewriters more convenient and efficient for use in business offices. Typewriter sales peaked after World War II; in response to a demand for typewriters capable of faster output, Smith Corona introduced electric typewriters in 1955. Electric portables, intended for traveling writers and business people, but later widely purchased for general home use, were introduced in 1957. The new portable electric typewriters would become an essential tool for generations of U.S. high school and college students.
