Global communication. Computer artwork representing the concept of global communication. The image shows a businessman, backdropped against a city with his head replaced by a mobile telephone. The telephone is emitting wave signals (shown as coloured circles) and is displaying a picture of the globe. The mobile or cellular telephone has had a dramatic impact on the business world. Coupled with the use of laptop computers it is now possible to stay in touch with the business world without leaving one's home or car.
