It was during this same period that cultures and societies around the world were being affected by a rapid increase in intercontinental travel and commerce. Books and magazines published on one continent could be exported and sold on another with increasing ease, and the development of reliable mail services facilitated individual exchanges of ideas, techniques and, most importantly for photography, actual prints. These developments led to pictorialism being "a more international movement in photography than almost any other photographic genre." Camera clubs in the U.S., England, France, Germany, Austria, Japan and other countries regularly lent works to each other's exhibitions, exchanged technical information and published essays and critical commentaries in one another's journals. Led by The Linked Ring in England, the Photo-Secession in the U.S., and the Photo-Club de Paris in France, first hundreds and then thousands of photographers passionately pursued common interests in this multi-dimensional movement. Within the span of little more than a decade, notable pictorial photographers were found in Western and Eastern Europe, North America, Asia and Australia.
