The company was founded by Dhirubhai Ambani in 1966 and has grown significantly over the years through a combination of internal growth and acquisitions.

In recent years, Reliance Industries has made a number of acquisitions in a variety of industries, including the acquisition of Hamleys, a British toy retailer, and the acquisition of a majority stake in Network18, a media company that operates a number of news channels and websites in India. These acquisitions have allowed Reliance Industries to expand its operations and diversify its business.
