Adobe data shows 55% of buyers shopping on mobiles.
Data released by Adobe said online spending on Black Friday and Thanksgiving Day in the US increased by 17.7% to $5.27bn compared to last year’s spending.
Spending on Black Friday was up 21.6% to $3.34bn compared to sales on the same day a year ago, while Thanksgiving accounted for the remaining $1.93bn with 11.5% growth in sales, it said.
US sales recorded on Black Friday have set a new record, surpassing the three-billion-dollar mark for the first time.
Also, Black Friday saw mobile revenue exceeding the one-billion-dollar-mark for the first time in retail space, with sales reaching $1.2bn, up 33% on year-over-year basis.
Lego Creator Sets, electric scooters from Razor, Nerf Guns, DJI Phantom Drones and Barbie Dreamhouse emerged as the top five selling toys.
The five top selling electronic products on Black Friday include Apple iPads, Samsung 4k TVs, Apple MacBook Air, LG TVs and Microsoft Xbox.
Adobe Digital Insights principal analyst and director Tamara Gaffney said: “Shoppers hit the buy button at unprecedented levels as conversion rates were up nearly a full percent across all devices in the evening hours on Black Friday.
“With the full day total coming in at $3.34 billion, Black Friday may have just dethroned Cyber Monday’s position as the largest online shopping day of the year. Shoppers are still buying at higher than expected levels in the early morning hours of Small Business Saturday.”
A majority of buyers on Black Friday shopped through mobiles, with 45% of them visiting retail websites from smartphones and 10% from tablets.
