According to new research commissioned by Google the internet contributes £100 billion a year to the UK economy.
Google's research, carried out by Boston Consulting Group (BCG), claims that the internet accounts for 7.2 per cent of the UK's gross domestic product (GDP).
The figures show the UK's internet economy to be Britain's fifth largest economic sector, bigger than the transport industry and the construction industry.

"The internet is a central pillar of the UK's economy," adds the Google UK boss. "The sector has come of age, and with great prospects for further growth the UK internet economy will be vital to the UK's future prosperity."
