Dhirubhai Ambani, who was the founder of Reliance was a very astute businessman with his ability to think ahead and generate a great return on the money.  With such a business sense, Reliance became one of the biggest companies in India and the Ambanis became one of the richest families in India. The cash-rich business of Oil went to Mukesh Ambani after the division of the two brothers. Later with Jio he entered into the Digital market and soon coined that “Data is the new Oil”.
