In this issue of InternetRetailing we examine Christmas 2017 and look at how retailers performed. The Yoox Net – A – Porter Group, reported “outstanding results” as 96% of its sales took place on Cyber Monday on mobile. Whilst for others, for example, Marks and Spencer, the trading quarter was more challenging. We look ahead to the trends for the year, including thoughts from industry heavy weights, Lord Stuart Rose, Sir Terry Leahy, and Tim Mason on the changeover of retailing 2017-2018. Our lead interview is with Ross Clemmow, Managing Director, Debenhams on differentiating through social shopping.
