It is a sub-category of the concept of the ultra high-net-worth individual. The American business magazine Forbes produces a global list of known U.S. dollar billionaires every year and updates an internet version of this list in real time. The American oil magnate John D. Rockefeller became the world's first confirmed U.S. dollar billionaire in 1916.
The Forbes 400 or 400 Richest Americans is a list published by Forbes magazine of the wealthiest 400 American citizens who own assets in the U.S., ranked by net worth. The 400 was started by Malcolm Forbes in 1982 and the list is published annually around September. Peter W. Bernstein and Annalyn Swan describe the Forbes 400 as capturing "a period of extraordinary individual and entrepreneurial energy, a time unlike the extended postwar years, from 1945 to 1982, when American society emphasized the power of corporations." Bernstein and Swan also describe it as representing "a powerful argument – and sometimes a dream – about the social value of wealth in contemporary America."
