5 insights into the lives of billionaires, from the producers of hit TV drama 'Billions'

The highly anticipated television series, "Billions," premiered last week and became Showtime's best-performing premiere ever.

The show centers around a hedge fund billionaire and the US attorney with a perfect track record of insider trading convictions.
