Online shopping has moved into the mainstream as November-December 2010 shopping season jumped 12% to $32.6 billion, according to the latest numbers from comScore:

Gian Fulgoni, comScore chairman, said that the numbers exceeded expectations.

"We saw spending increase at a rate of 12 percent for the season, outpacing our forecasted 11-percent growth, and set a new holiday season record as total e-commerce spending reached $32.6 billion. This year, retailers targeted many of their promotions even earlier than usual and reaped the benefits. The season will be remembered for an exceptional Cyber Monday, which was the first billion-dollar spending day in history, and the first time we've witnessed Cyber Monday rank as the heaviest online spending day of the year."

For the first time since comScore began tracking e-commerce activity in 2001, Cyber Monday (Monday, Nov. 29) ranked as the heaviest online spending day of the year at $1.028 billion. It also registers as the first online spending day on record to surpass the $1 billion spending threshold. Green Monday (Monday, Dec. 13) ranked as the second heaviest day at $954 million, followed by Monday, December 6 at $943 million. Free Shipping Day (Friday, Dec. 17) ranked fourth at $942 million, while Thursday, December 16 rounded out the top five with $930 million. Eight days in total surpassed $900 million in spending this holiday season.
