May 13, 1973: The Gamma-Sygma Split

Link:

It was an evening in May forty years ago, 1973. Disgruntled photographers from the Gamma agency decided to haul away their archives to open a new agency, Sygma. From the schism and the competition that ensued (complicated by a third agency, Sipa), the Golden Age of French Photojournalism was born, along with the global supremacy of French photo agencies.
