Or Should we say when a city became a term..."Bangalored" is a term used of late, when a company offshores their work that is not part of their core competencies to a company that is located in far shores (most often India or China). Bangalore is mostly where the companies which engage the work in India have their headquarters. The climate here is too good and probably that is the reason why Bangalore has got the edge over the other state in India. There is a healthy competition between the major cities in India to attract investment from the companies from the developed countries.
Bangalore is my home-town - its located down south in the Karnataka state. Though it is not part of the 4 metropolitan cities that were identified earlier in the history of India (Delhi, Mumbai, Chennai and Kolkata), it is now the most important city in terms of the emerging growth of Information Technology in India. This city is where the action happens in the field of Information Technology and Bio-technology.
Bangalore was known earlier for public sector heavy industries—particularly aerospace, space and defence. Bangalore is referred to as the Silicon Valley of India and accounts for 35 percent of India's software exports. The city has the second-highest literacy rate among the metropolitan cities in the nation. Bangalore is India's fourth largest and fastest growing markets. Bangalore is the 3rd most populous city in India and the 27th largest city in the world by population - showing its demand for people from cities all over India.
The name has been changed recently to Bengaluru (which was its name before the British changed it long ago). But, people still refer to it as Bangalore. The picture shows Vidhana Soudha - seat of Karnataka state's Legislative assembly.
