I have a close friend who worked in the City for many years. When we first met, which was just over twenty years ago, he told me he was an analyst. I asked him what he was analyzing. "Telecoms," he said. I asked him if that was big enough to be a field of its own. Surely it wasn't as big as steel or retail or chemicals or insurance. Obviously everyone had a phone and some people were getting these mobile ones but it still didn't seem substantial enough to qualify as its own industry.
I thought back to this yesterday when I was walking towards Kings Cross after the match. The day was sunny, the team had won and everyone was out on the streets doing something with their phone. Talking, texting, tweeting, checking the score, looking at video, sending each other elaborate jokes. What he should have said to me twenty years ago is that he was involved in the biggest step forward for the toy trade the world had ever seen. That would have been nearer the truth.
