Today there are hundreds of millions of digital images of child porn on the Internet accessible to people around the world.

This radical development means that more children are being abused than ever, with a growing number from the third world and a growing number who are misled into filming themselves with webcams.

Even more shocking is what this implies about the number of people who look at child porn.

NSPCC head Jon Brown tells the BBC:

"The inhibitions are too few, especially if men are in a room by themselves - it's too easy," he said.
