The Dolan Family – $5.7B
Media mogul Charles Dolan should be thanked for the rise of prestigious cable TV seeing as he started HBO in the 1970s. He later founded his flagship company, Cablevision, and it spun off into other major cable channels, such as the Sundance Channel, IFC and AMC. Although Dolan doesn’t own Cablevision (or HBO) anymore, his impact simply cannot be denied. His children own major sports teams like the New York Knicks and the Cleveland Indians. In addition, he has a son who serves as a news network’s president, and another who is the chairman of the Madison Square Garden Company.
The Bechtel Family – $3.3B
The fabulous wealth of the Bechtel family is mainly due to their successful massive construction company called the Bechtel Corporation. Over a century ago, cattle farmer Warren Bechtel started the company and within a few decades, it was constructing railroads across America. However, the firm’s biggest moneymaker was its historic project: the Hoover Dam construction in the 1930s. Soon Bechtel was building pipelines, malls, metros and nuclear reactors across the world under the leadership of the current owner Stephen Bechtel Jr., grandson of its original founder, and his son Riley.
