 An early challenge to its independence came in June 1940 when wartime censorship was imposed, meaning that the Department of Information (headed by Sir Keith Murdoch) took control of the ABC's 7 p.m. nightly national news bulletin.This lasted until September, when control of the news was returned to the ABC after listeners expressed a preference for independent news presented by the Commission.During the war, the ABC's news bulletins attained a reputation for authority and independence, and from 1942 onwards, were broadcast three times daily through all national and most commercial transmitters.
