into India by the British, in an attempt to break the Chinese monopoly on tea. The British, using Chinese seeds, plus Chinese planting and cultivating techniques, launched a tea industry by offering land in Assam to any European who agreed to cultivate tea for export. Tea was originally only consumed by Anglicized Indians; it was not until the 1950s that tea grew widely popular in India through a successful advertising campaign by the India Tea Board. Prior to the British, the plant may have been used for medicinal purposes. Some cite the Sanjeevani plant as the first recorded reference of tea use in India. However, scientific studies have shown that the Sanjeevani plant is in fact a different plant and is not related to tea. The Singpho tribe and the Khamti tribe validate that they have been consuming tea since the 12th century. However, commercial production of tea in India did not begin until the arrival of the British East India Company, at which point large tracts of land were converted for mass tea production. The Chinese variety is used for Sikkim, Darjeeling tea, and Kangra tea, while the Assam variety, clonal to the native to Assam, was used everywhere else. The British started commercial tea plantations in India and in Ceylon: "In 1824 tea plants were discovered in the hills along the frontier between Burma and Assam. The British introduced tea culture into India in 1836 and into Ceylon (Sri Lanka) in 1867. At first they used seeds from China, but later seeds from the clonal Assam plant were used." Only black tea was produced until recent decades mostly in India, except in Kangra (present-day Himachal Pradesh) which produced green tea for exporting to central Asia, Afghanistan and neighboring countries. India was the top producer of tea for nearly a century but was displaced by China as the top tea producer in the 21st century. Indian tea companies have acquired a number of iconic foreign tea enterprises including British brands Lipton, Tetley, Twinings and Typhoo. Most of the Indian tea garden owners have focused on exports to markets like Europe and Russia, while very few have focused on building their own brands such as Makaibari, Dharmsala Tea Company, and a few others. While India is the largest consumer of tea worldwide, the per-capita consumption of tea in India remains a modest 750 grams per person annually. Recently consumption of
