The UK has the largest internet economy in the G20 group of industrialised nations according to research conducted by the Boston Consulting Group.

It estimates that the UK's internet economy was worth £121bn in 2010, more than £2,000 per person. This would make it bigger than the healthcare, construction or education sectors.

Report author Paul Zwillenberg told the BBC how the internet economy is measured and what the findings mean.
