The cultivation and brewing of tea in India has a long history. Commercial production of tea in India begins with the arrival of the British East India Company, at which point large tracts of land were converted for mass tea production. The widespread popularity of tea as a recreational drink begins in the 1950s, after a successful advertising campaign by the India Tea Board. Today, India is one of the largest tea producers in the world, though over 70% of the tea is consumed within India itself. A number of renowned teas, such as Assam and Darjeeling, also grow exclusively in India. The Indian tea industry has grown to own many global tea brands, and has evolved to one of the most technologically equipped tea industries in the world. Tea production, certification, exportation, and all other facets of the tea trade in India is controlled by the Tea Board of India.
