The photocopy is patented – Social Futuro

On October 6, 1942, Chester Carlson issued a patent on a process called electrophotography. It was later referred to as Xerography commercially. Today it is known as a photocopy. It wasn’t until 1946 that a company finally became interested in photocopying commercially. The Haloid Company (The Haloid Photographic Company), now known as Xerox, licensed Carlson’s patent and created the word “xerography” to differentiate the process from conventional photography. Eventually, photocopying became the company’s main source of income, so Haloid changed its name to Xerox.
