I realised it had been months since I'd seen a teenager without a computer or smartphone in their hand. I decided there and then to make a film on the subject, the beginning of a year-long journey that took me from the fibre-optic cables in the sewers of London to spending endless, unedifying hours in bedrooms of teenage boys as they watched porn.
