Cyber Monday reached $3.36 billion in desktop online spending this year, reports cross-platform measurement firm comScore. The spending increased 26 percent from last year, and ranks 2017 as the top U.S. online spending day in history.

The weekend following the Thanksgiving holiday was also strong, marking the third straight year in which both Saturday and Sunday individually had billion-dollar online shopping days, combining for $2.92 billion for a year-over-year increase of 17 percent. For the five-day period from Thanksgiving through Cyber Monday, online buying from desktop computers totaled $10.21 billion, up 21 percent versus last year.

“Cyber Monday once again ranked as the heaviest online spending day of all time and became the first day to ever exceed $3 billion in sales from desktop computers,” says comScore SVP of Marketing and Insights Andrew Lipsman. “Every year it seems there’s talk of the big promotional days becoming less important as promotions get extended across so much of the season, but the data suggest the exact opposite—that the biggest promotional days are only getting more important with time. Online retailers have conditioned consumers to be very responsive to the deals on Black Friday and Cyber Monday, which is why they have consistently shown above-average growth rates year after year.”

comScore’s data shows that 140 million Americans visited online retail properties on Cyber Monday, with 77 million arriving via desktop, 103 million via mobile and 40 million shopping on both platforms. The total number of digital shoppers on Cyber Monday surpassed Black Friday’s total by 11 million. Amazon once again ranked as the most visited online retail property on Cyber Monday, followed by Walmart and eBay, and apparel and accessories ranked as the top product category with nearly $900 million in desktop sales.
