Information superhighway. Abstract artwork of the information superhighway, showing a stream of code letters whizzing around the Earth. The information superhighway is an ever-growing network of fibre optic cables that can link computers, televisions, phones and the communications technologies of the future to a universal digital system. Film, sound and computer data can all be reduced to a stream of zeroes and ones and sent along the cables at the speed of light. The superhighway is expected to revolutionise the media and computing industries, making possible new services such as lifelike videophones and interactive television.
