The US holiday shoppers have spent about $1bn in online shopping during the Thanksgiving weekend, marking the highest surge in E-Commerce spending for the first time over $816m spent during the corresponding day in 2011, according to a new report.

comScore’s report revealed that the online spending also increased 32% during the Thanksgiving Day to $633m when compared to the same day in 2011.

comScore chairman, Gian Fulgoni said in spite of the frenzy of media coverage surrounding the importance of Black Friday in the brick-and-mortar world, the shopping day has been more prominent in the e-commerce channel – particularly among those who prefer to avoid crowds at the stores.

"With Black Friday online sales up 26 percent and surpassing $1 billion for the first time, coupled with early reports indicating that Black Friday sales in retail stores were down 1.8 percent, we can now confidently call it amulti-channelmarketing phenomenon," Fulgoni said.

"Meanwhile, Thanksgiving Day – which has historically been a lighter online holiday shopping day – continues to gain steam and grew well ahead of the current pace as more consumers opted to kick off their holiday shopping immediately after the big meal to take advantage of aggressive retailer promotions.

The report also anticipates the online sales on the Cyber Monday to reach $1.5bn marking the heaviest online sales day of the season.

During the Black Friday, Amazon topped the list with highest number of online sales followed by Wal-Mart Stores, Best Buy, Target and Apple, the report revealed.

Of all the online shopping stuff, Digital content and subscriptions, including e-books, digital music and video, reported 29% rise in sales, followed by toys, consumer packaged goods, video game consoles & accessories and consumer electronics respectively over the Black Friday last year.

According to a report from IBM, the online spending increased 17.4% on Thanksgiving Day, which had set a stage for 20.7% growth on Black Friday, due to a surge in orders of mobile devices and tablet computers.
