Ten years ago, before I had an internet connection or Amazon started turning a profit, I remember being at my Nan's and the TV was on. During the programme break there was an advert for Amazon.co.uk. As a 75 year-old she dismissed the internet as a fad. A strange attitude to have for someone born 18 months before the first demonstration of the very thing she's sitting in front of. I do love the smugness that comes from looking back on that.
