In a post entitled Bill Gates previews Vista of new television landscape, informitv reports on remarks of BBC's director of new media and technology, Ashley Highfield:  "...

He said the cost of delivering a television channel over the air is around £7 million a year using digital terrestrial television, and around £700,000 over satellite.
