The state electronics corporation (Keonics) began developing Electronic City on the southern edge of the city in the late 1970s. Texas Instruments opened a design centre in Bengaluru in 1985, one of the first multinational R&D centres in India. Infosys moved its headquarters here in the early 1980s and Wipro turned to software in the same era.
The 1991 economic reforms and the growth of offshore software services made Bengaluru India's leading technology city. Later came the startup generation, including Flipkart, Swiggy, Zerodha and many others, and global capability centres for hundreds of multinationals. The same growth brought the traffic, water stress and lake loss that dominate local news today.
