The BBC's Director-General Tony Hall has set a target for the corporation to reach 500 million people worldwide by its centenary in 2022.
"As we move towards our centenary, my vision is of a confident, outward-looking BBC which brings the best of our independent, impartial journalism and world-class entertainment to half a billion people around the world. Today is a key step towards that aim," he said.
"We must follow our audience, who consume the news in changing ways; an increasing number of people are watching the World Service on TV, and many services are now digital-only," BBC World Service Director Francesca Unsworth said.
"We will be able to speed up our digital transformation, especially for younger audiences, and we will continue to invest in video news bulletins," he added.
