A billionaire, in countries that use the short scale number naming system, is a person with a net worth of at least one billion units of a given currency, usually major currencies such as the United States dollar, the euro or the pound sterling. Additionally, a centibillionaire has been deemed applicable to a billionaire worth one hundred billion dollars (100,000,000,000), a mark first achieved in 2017 by Amazon founder Jeff Bezos, with a net worth of $112 billion in a report issued in early 2018. 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, and still holds the title of history's wealthiest individual.
The Forbes 400 or 400 Richest Americans is a list published by Forbes magazine of the wealthiest 400 American residents, 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."
The Forbes list of Indian billionaires is based on an annual assessment of wealth and assets compiled and published by Forbes magazine in 2018.
