In 2014, Prime Minister Shri Narendra Modi launched a monthly radio program, Mann Ki Baat. In a world dominated by social media and television, it seemed a strange choice. Little did the world realize what a masterstroke it was. By 2023, when he completed his hundredth episode, 1 billion people had listened to the show at least once! In this book, researchers from IIT Madras use policy advocacy frameworks and systems theory to analyze Mann Ki Baat and demonstrate that it has gone beyond being just a radio show to being a 'life-centric living system'. Mann Ki Baat has empowered citizens and brought about transformational capacity of people in India. The book also presents a case study of how the IIT Madras ecosystem has built transformational capacity around innovation and entrepreneurship.
