It was also used in Scandinavia during the Middle Ages, but was subsequently replaced with ⟨dh⟩, and later ⟨d⟩.
Monotype Imaging Holdings Inc., founded as Lanston Monotype Machine Company in 1887 in Philadelphia by Tolbert Lanston, is an American (historically Anglo-American) company that specializes in digital typesetting and typeface design for use with consumer electronics devices. Based in Woburn, Massachusetts, the company has been responsible for many developments in printing technology—in particular the Monotype machine, which was a fully mechanical hot metal typesetter, that produced texts automatically, all single type. Monotype was involved in the design and production of many typefaces in the 20th century. Monotype developed many of the most widely used typeface designs, including Times New Roman, Gill Sans, and Arial.
