TCS is India's largest IT services company and one of Tata Group's most valuable subsidiaries. Founded in 1968 as part of Tata's expansion into the services and technology economy, TCS exemplifies how sparse network topology creates resilience through isolation.
Operating since the 1990s as a pioneer in India's IT services industry, TCS helped prove that India could deliver enterprise-scale software at competitive costs - establishing the foundation for Bangalore's evolution into a global tech hub. When parent company Tata Motors hemorrhaged cash during the 2008-2013 Jaguar Land Rover crisis, TCS remained insulated and posted record profits, growing from $6 billion to $13 billion in revenue.
The sparse topology meant TCS shared only brand and dividends with other Tata companies, not balance sheets or operations. This contagion resistance enabled continued growth while sister companies struggled. TCS demonstrates that network architecture matters as much as network size - loose coupling can be a feature, not a bug, when it prevents cascading failures across the system.
