The Kinetoscope was also gaining notice on the other side of the Atlantic. In the summer of 1894, it was demonstrated at 20, boulevard Poissonnière in Paris; this was one of the primary inspirations to the Lumière brothers, who would go on to develop the first commercially successful movie projection system. On October 17, 1894, the first Kinetoscope parlor outside the United States opened in London. Dissemination of the system proceeded rapidly in Europe, as Edison had left his patents unprotected overseas. The most likely reason was the technology's reliance on a variety of foreign innovations and a consequent belief that patent applications would have little chance of success. An alternative view, however, used to be popular: The 1971 edition of the "Encyclopædia Britannica", for instance, claims that Edison "apparently thought so little of his invention that he failed to pay the $150 that would have granted him an international copyright ." As recently as 2004, Andrew Rausch stated that Edison "balked at a $150 fee for overseas patents" and "saw little commercial value in the Kinetoscope." Given that Edison, as much a businessman as an inventor, spent approximately $24,000 on the system's development and went so far as to build a facility expressly for moviemaking before his U.S. patent was awarded, Rausch's interpretation is not widely shared by present-day scholars. Whatever the cause, two Greek entrepreneurs, George Georgiades and George Tragides, took advantage of the opening. Already successfully operating a pair of London movie parlors with Edison Kinetoscopes, they commissioned English inventor and manufacturer Robert W. Paul to make copies of them. After fulfilling the Georgiades–Tragides contract, Paul decided to go into the movie business himself, proceeding to make dozens of additional Kinetoscope reproductions. Paul's work would result in a series of important innovations in both camera and exhibition technology. Meanwhile, plans were advancing at the Black Maria to realize Edison's goal of a motion picture system uniting image with sound.
