Chennai remains the chief retail industry and shopping centre in South India, with some of its suburbs serving as exclusive shopping districts. Since the formation of the city in the seventeenth century, George Town remains one of the chief commercial neighbourhood of the city. However, with the centuries passing, the central business district of the city started shifting towards the south of Fort St. George and moving to its present location at Gemini Circle. The city's retail industry is concentrated chiefly in T. Nagar, which is by far the largest shopping district of India, generating more than twice the revenue of Connaught Place in New Delhi or Linking Road in Mumbai, even by conservative estimates.[1]
