Retail e-commerce spending in the US, excluding travel, reached $27.2 billion (£13.45bn) in the second quarter of 2007, up 23% from the same quarter last year, according to a report released by comScore.

Online travel spending was $20.3bn (310.04bn) in the second quarter, up 14% year-over-year, while total US e-commerce spending for the quarter was up 19% from last year to $47.5bn (£23.49bn), according to comScore. Total e-commerce spending for the first half of 2007 was $95bn (£47bn), comScore said.

Online spending on video games, consoles and accessories was up 159% in the second quarter of this year compared with a year ago, comScore said. This category was boosted by sales of the Nintendo Wii and PlayStation 3. Online spending on sports and fitness was up 58% year-over-year, followed by consumer electronics, up 51% from last year, and event tickets, up 44%, according to comScore.

In 2006, US consumers spent $170.8bn (£84.47bn) online, including $102.1bn (£50.5bn) on retail e-commerce and $68.8bn (£34.03bn) on travel, comScore said. Total US consumer online spending should reach $200bn (£98.9bn) in 2007, the company said.

“However, in the past, we've seen growth rates accelerate as the year progresses, culminating with the online holiday shopping season, so $200bn (£98.9bn) may actually turn out to be a conservative estimate,” said Gian Fulgoni, comScore chairman, in a statement.
