The Fortune Global 500 company had a humble beginning in 1957 when Dhirubhai Ambani started a yarn trading business. Dhirubhai Ambani founded Reliance Textiles Industries in 1973. The company started its operations in textiles, but soon diversified into other sectors such as petrochemicals and refining.

RIL entered the telecommunications sector in the 1990s and became a major player. The company also ventured into the retail segment in 2006 and became the largest retailer by 2014.
The flagship company of the conglomerate comprises its core businesses of oil refining and marketing; petrochemicals; oil & gas exploration; and production. It is the largest petroleum refiner in India and a major producer of petrochemicals.
Under the oil & gas exploration business, the company made a significant deep-sea discovery of gas reserves in the Krishna Godavari basin—the KG D6 Block–in 2002-2003. Reliance also has two coal bed methane (CBM) blocks in Madhya Pradesh.
The company is also a major refiner and its Jamnagar refinery is the largest single-site refinery in the world.
