The Indian IT industry accounts for over 5% of India's GDP and has experienced significant growth in recent decades, driven by factors such as liberalized immigration policies, government initiatives to promote the sector, and economic reforms. India is now a major global outsourcing hub, with cities like Bangalore emerging as major IT centers, though the industry was impacted by the 2008 financial crisis. The roots of India's IT industry date back to the 1960s with early companies like Tata Consultancy Services and initiatives by the government to build a skilled technical workforce.
