market its own "Monophoto" phototypesetting systems, but these suffered from problems. Its first devices were heavily based on hot metal machinery, with glass pictures of characters which would be reproduced on photographic paper replacing the matrices used to cast metal type. While this reduced the need for retraining, the resulting devices often set type slowly compared to legacy-free next-generation devices from providers such as Photon and Compugraphic, and were often more expensive. Its devices were slow to incorporate use of electronics, and while its type library was of high quality, changing tastes and the development of other companies' libraries competed with this. Its type library was also easily pirated, since fonts have only limited copyright protection. The company was eventually split into three divisions: Monotype International, which manufactured spinning mirror switched laser beam phototypesetters; Monotype Limited, which continued the hot metal machines; and Monotype Typography, which designed and sold typefaces. A research and development department was set up in Cambridge to isolate it from day to day production issues. Monotype in the UK continued to enjoy prestige through the 1970s with the patronage of major British printers such as the university presses at Oxford and Cambridge; it also enjoyed some success with its Lasercomp laser-based typesetting system from the 1970s onwards, developed by the Cambridge research group. However, new technology and finally publishing software such as Quark XPress and Aldus PageMaker running on general-purpose computers ate away at its competitiveness in the market of complete typesetting solutions by the 1990s. Monotype, however, has continued in business, for instance marketing typeface designs to third-party buyers, computing companies such as Microsoft (many fonts on Microsoft computers in particular are Monotype-designed) and companies and organisations such as London Transport and the UK parliament requiring custom digital typefaces. Much of its metal type equipment and archives were donated to the Type Museum collection in London; other materials are held at St Bride Library. The history and decline of the hot metal American Lanston Monotype Corporation is described in full detail by Richard L. Hopkins, in Tolbert Lanston and the Monotype. The origin of digital Typesetting. In 2004, P22 type foundry bought the "Lanston Type Co." from Gerald Giampa.
