NEW YORK, United States — The five-day Thanksgiving shopping period saw combined sales at 80 of the largest 100 US web retailers rise more than 23 percent over last year to $24.2 billion, according to Adobe Analytics. Not only did Cyber Monday rack up the most purchases — as in years past — but revenue of $7.9 billion made it the largest online shopping day of all time in the US, the group's data showed. Mobile transactions soared, with $2.2 billion of the day's sales originating from smartphones. "Sales coming from smartphones hit an all-time high," said John Copeland, head of Marketing and Customer Insights at Adobe. "We saw a significant spike in the Buy Online, Pick Up In-Store trend."
