Despite retailers offering holiday discounts earlier than usual this year, US consumers did more shopping on Black Friday than the days leading up to it.

Chatbots and Buy Now, Pay Later (BNPL) were huge emerging forces during this year's Black Friday, according to Adobe Digital Insights.

British shoppers spent 3.63 billion pounds ($4.6 billion) online over the Black Friday/Cyber Monday (Nov. 29-Dec. 2) period, a 5.2% increase year-on-year, according to data from Adobe Analytics published on Tuesday.
