Zivin, Joselyn Amy, The projection of India: Imperial propaganda, the British State and Nationalist India, 1930-47, PhD thesis, Duke University, 1994. Brief summary.

“In the wake of the First World War the British colonial government established the core of what became an internally embattled global network charged with defending British rule in India. Officials in New Delhi and London recognized the fundamental threat that the Indian national movement under Mohandas Gandhi posed to colonial legitimacy both in India and abroad. At the same time, the propaganda legacies of the War would not be easily shelved; these included the development of mass communications technologies and the strategies with which Britain and its enemies had employed them. By the 1930s the Indian national movement had proven superior at using these strategies on the world stage of public opinion, largely through Gandhi's self-orchestrated emergence as the embodiment of a reworked orientalist image of India. In response the transnational colonial state intensified its own propaganda, a project integrally tied up with the broader development of a bureaucratic apparatus for the control and dissemination of official information. In Britain the India Office Information Department courted and admonished the press, produced propaganda materials, and monitored the BBC and other government agencies. In India, the fate of government radio broadcasting and an instrumentally liberal information policy evidenced the alienation of the British structure of rule from public opinion. During the Second World War Britain's communist and fascist enemies and its American allies joined the Indian national movement in its assault on British imperialism. Britain's global claims to be ensuring political stability in a divided India did nothing to earn the reputation of a visionary world power, while attempts to promote Britain's war mission in India itself illustrated the ideological and political bankruptcy of the colonial administration. By the end of the war Britain's colonial rule in India had expired and a new world hierarchy was in place in which Britain was fully subordinate to the United States. In this context British propagandists turned to the neo-imperial and thus doomed 'Commonwealth Idea,' with its emphasis on equal partnership under British leadership. Independent India, meanwhile, inherited Britain's propaganda structures along with the rest of the colonial legacy. They are still in use today.” From the abstract.
