It’s that time of year again: survey time. This means I get five weeks to write about 12,000 words on a single subject. It’s rather like doing a short book. This year’s topic: the trillion-dollar telecoms industry, which is in something of a mess following the bursting of the technology bubble. But, I argue, things are not as bad as they look. There is still scope for growth in mobile phones, broadband and various whizzy new kinds of internet services for large companies. Inevitably, there’s a telegraph reference in there too.
