The first quarter of the year saw a "strong acceleration" in online spending in the US, with consumers shelling out $34 billion (£23.5 billion) between January and March.
In good news for users of internet marketing services, figures from comScore showed that spending on ecommerce was ten per cent higher when compared with the opening three months of 2009.
It added that this is the first time that growth in online expenditure has reached double digits since the second quarter of 2008.
Much of the rise in spending was driven by upper income households, with those earning over $100,000 a year increasing their outlay on internet shopping by 14 per cent.
Elsewhere, comScore said that pureplay retailers, companies that only sell online, continued to gain market share from multi-channel brands.
The company’s chairman Gian Fulgoni commented: "Should the economy falter in the second half of the year and upper income consumers return to a savings mode, we could still see growth decelerate. But for the time being, this momentum is encouraging."
According to eMarketer, US spending on online advertising is set to hit $25.1 billion in 2010.
