The surge of activity on mobile devices helped push U.S. Cyber Monday online sales to $3.118 billion, up 20.5% from $2.586 billion on the Monday after Thanksgiving in 2014, according to comScore Inc. The online shopping holiday accounted for more than 8% of overall online sales in November, according to comScore.

The good news surrounding the holiday shopping weekend just keeps on coming for online retailers.

Shoppers spent a combined $3.118 billion online on the Monday after Thanksgiving, or Cyber Monday as it’s known, up 20.5% from $2.586 billion in sales on Cyber Monday last year, according to comScore Inc. That’s in line with data released by Adobe Systems Inc. on Tuesday, which reported that online sales reached the $3.07 billion mark, the first time online sales have surpassed $3 billion in a day.

ComScore’s data shows that sales completed through mobile devices more than doubled year over year on Cyber Monday, with shoppers spending $838 million on mobile devices that day, up 52.9% from $548 million on the same day last year. Mobile commerce is estimated to have accounted for 27% of total digital commerce on Monday, comScore says.

Cyber Monday also proved to be the biggest day of the holiday shopping weekend on desktops, with sales of $2.280 billion eclipsing sales on desktops on Saturday and Sunday combined ($2.169 billion). The $2.280 billion in sales via desktop on Cyber Monday this year is up 11.9% from $2.038 billion in sales on the same day last year.

This growth comes despite the fact that more retailers opted to spread online deals g across a number of days, rather than waiting for Cyber Monday.


“Despite some talk of Cyber Monday declining in importance, the day’s historical highs and continued strong growth rates confirm it is still a hugely important shopping event,” comScore chairman emeritus Gian Fulgoni said.

While more buyers were shopping from home (51.4%) than work (47.8%), comScore’s data shows that more money was spent on work computers (52.2%) than on home computers (47.8%). Inc., No. 1 in the Internet Retailer 2015 Top 500 Guide, drew the lion’s share of traffic on the day, followed by Wal-Mart Stores Inc. (No. 3), eBay Inc., Target Corp. (No. 16) and Best Buy Co. Inc. (No. 14).

Online sales for November came in at $27.898 billion, up 6.1% from $26.290 billion during the same time last year. Cyber Monday alone accounted for 8.2% of online sales during the month, compared to 7.8% last year.
