BBC Worldwide's plans include growing the number of its TV channels around the world from 28 to 40. In January, it acquired a 25% stake in Australian TV production company Freehand Group, helping it build a network of production bases around the world.
Its plans also include content licensing to other media operators, such as the deal announced on Friday with . BBC Worldwide will have its own entertainment channel on YouTube showing clips from the likes of 'Top Gear', 'Spooks' and 'The Mighty Boosh'. The channel will carry advertising.
Smith also talked about Worldwide's UK magazine division's proposed launch of a weekly news magazine, News Brief, saying he has not greenlighted it.
He said: "It does look good. But it will not be approved until I am convinced of the business plan."
He said he would investigate an expansion of the magazines business though acquisitions and joint ventures with publishers producing lifestyle and factual quality magazines.
