8. Koos Bekker $ 2.8 billion

The company operates in 130 countries and is listed on the London and Johannesburg Stock Exchanges, and has the largest market capitalization of any media company outside the US and China.
Bekker is revered as an astute executive who transformed South African newspaper publisher Naspers into an ecommerce investor & cable TV powerhouse.
