Reliance Industries Day

Reliance started their business with spices. The company was co-founded by Dhirubhai Ambani and Champaklal Damani in 1960's as Reliance Commercial Corporation. In 1965, the partnership ended and Dhirubhai continued the polyester business of the firm. In 1966, Reliance Textiles Engineers Pvt. Ltd. was incorporated in Maharashtra. It established a synthetic fabrics mill in the same year at Naroda in Gujarat. On 8 May 1973, it became Reliance Industries Limited. In 1975, the company expanded its business into textiles, with "Vimal" becoming its major brand in later years. The company held its Initial public offering (IPO) in 1977.

On 28th December 2002, the Ministry of Communications released a commemorative postage stamp featuring Dhirubhai Ambani. The stamp is a tribute to him and is issued by the Departments of Posts in the denomination of 5 rupees.
