Great article on the BBC about how much the internet market place is worth.
If the internet was an economic sector it would be the UK's fifth largest, said the report from the Boston Consulting Group (BCG).
This would make the sector larger than the construction, transport and utilities industries.
Some 60% of the £100bn a year figure is made up from internet consumption - the amount that users spend on online shopping and on the cost of their connections and devices to access the web.
The rest comes from investment in the UK's internet infrastructure, government IT spending and net exports.
The report, The Connected Kingdom: How the internet is transforming the UK, says that the internet's contribution to GDP is set to grow by about 10% annually, reaching 10% of GDP by 2015.
The UK, according to the report, is the world's leading nation for e-commerce. For every £1 spent online to import goods, £2.80 is exported.
"This is the opposite of the trend seen in the offline economy, which exports 90p for every £1 imported," the report says.
The report also attempts to compare the UK to other countries in the Organisation for Economic Co-operation and Development (OECD).
Under its scoring system, the UK ranks sixth, above Germany, the US and France. The highest ranked country is Denmark.
"The internet is pervasive in the UK economy today, more so than in most advanced countries," said Paul Zwillenberg, partner with BCG.
"Several industries - including media, travel, insurance and fashion - are being transformed by it."
Matt Brittin, managing director of Google UK, said: "The internet is a central pillar of the UK's economy.
"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," he added.
