Estimated fortune: 198 billion.

History: The wealthy Kühn family, concentrating their efforts on the dream of a universal telephone system, migrated from Germany to the United States at the end of World War I, willing to invest 33 million dollars in values of that time in a conglomerate of subsidiaries of, until then, AA Company, the Telephone and Telegraph Inc., based in New York, affiliating with Joseph Waddel. Progressive and ahead of their time, the Welber brothers and Albert Kühn were pioneers in investing in experimental stations, guaranteeing, until the end of the 1930s, several transmission systems that began to be commercialized in New York in 1941, totaling about 525 lines throughout the national territory, which would provide the basis for television until the end of the century. Today, Kühn is the world's largest media conglomerate company, providing the very best in broadcasting, internet, and cable TV.
