Digital sales reached a record $5.03 billion, among the top sellers were Roku and the Nintendo Switch. On Black Friday itself, the tally for online spending was $5 billion, up massively from $3.34 billion past year.
And this is only the start, as online holiday spending is expected to reach $107 billion in sales - that's a 14 percent increase over 2016, reports CNBC.
Black Friday follows Thanksgiving Day that is observed on the fourth Thursday of November, heralding the Christmas shopping season.
According to data from Adobe Digital Insights, which tracks 80% of online spending at America's 100 largest retail websites, Cyber Monday will be even bigger than Black Friday, bringing in as much as $6 billion in digital sales.

According to Ipsos Retail Performance, UK footfall on Black Friday was up 0.95 per cent year-on-year, with 42 per cent of retailers experiencing footfall growth.
Black Friday sales failed to tempt shoppers on to high streets, casting new doubt over the wisdom of British stores' adoption of the United States retail event.
ShopperTrak senior executive Brian Field released a statement on the debate over the decline in in-store retail shopping. Last-minute mobile improvements and mobile-specific deals may boost conversion and avoid lost sales to competitors, as once consumers leave a mobile site or app, there is no guarantee they will come back or go to the corresponding brick-and-mortar location. The research firm had previously reported Cyber Monday sales of $3.45 billion previous year but restated that figure to $5.6 billion following a change in its methodology of calculating sales.
