Typewriter the first major typewriter with these features. However, older "nonvisible" models continued in production to as late as 1915. A significant innovation was the shift key, introduced with the Remington No. 2 in 1878. This key physically "shifted" either the basket of typebars, in which case the typewriter is described as "basket shift", or the paper-holding carriage, in which case the typewriter is described as "carriage shift".

By 1958 IBM was deriving 8% of its revenue from the sale of electric typewriters. In 1931, an electric typewriter was introduced by Varityper Corporation. It was called the "Varityper", because a narrow cylinder-like wheel could be replaced to change the font. Electrical typewriter designs removed the "direct" mechanical connection between the keys and the element that struck the paper. Not to be confused with later "electronic" typewriters, electric typewriters contained only a single electrical component: the
