How did jerry Jones make his fortune?

Answer 1

After several unsuccessful business ventures (including passing up the opportunity to purchase the AFL's San Diego Chargers in 1967 for the asking), he began an oil and gas exploration business in Oklahoma, Jones Oil and Land Lease, which became phenomenally successful. His company, a private family asset, currently does natural resource prospecting.

***************** I'd like to take a moment and add a bit to this answer. Jones' little company that was operating up there in Oklahoma wasn't successful. In fact, there were lots of problems. As I recall, there were problems getting the wells into production and given that they weren't able to produce the wells... he was able to buy them from the owners/investors for only penny's on the dollar all the while knowing that he had a deal to sell the wells to another party for a huge windfall. Some think it was smart business. Others might just think he wronged his own clients/investors. Regardless... it's ancient history now... irrespective of how it all went down. All I know is that I wouldn't do business with the guy under any circumstances.
