Records were broken for online sales during Christmas 2007, according to a new report from the Interactive Media in Retail Group (IMRG) and Capgemini.
The study, dubbed e-Retail Sales Index, reveals that £15.2 billion was spent over the internet in the 12-week period leading up to Christmas.
December's online sales were reportedly up 50 per cent on the same month in 2006, while e-retail spend for the whole of 2007 totalled £46.6 billion.
Anthoula Madden, vice president at Capgemini UK's consumer products and retail team, states: "Online growth has proven robust and sustainable over the past year, increasing its share of UK retail from 10p in the pound to 15p.
"Whilst we are yet to see high streets sales decline there can be no doubt online is growing its share at the expense of bricks and mortar retailers."
She also said that she believes the trend is set to continue in the coming years.
In Huddersfield, West Yorkshire, the trend proved to be different, according to the Huddersfield Daily Examiner.
The newspaper reported an Ask Marketing and Research agency survey, which found that people in the town favoured the high street over the internet when it came to their Christmas shopping.
