Just over two weeks ago, Matthew Robson had never worked in banking. This was mainly because he was 15 years old and attending a high school in South London.
Today he is the talk of Tokyo, Wall Street and London's financial district. Fund managers, CEOs and analysts are poring over his report, "How Teenagers Consume Media," which he wrote last week while on an internship at Morgan Stanley.
In it he laid out the world according to the teenager: a confusing place where the PC is a radio, the game console is a telephone, the cell phone is a stereo and text-message machine, DVDs are pirate copies and no one uses Twitter.
Sitting at home in Greenwich, near London, Monday, he explained that he was only relaying the daily conversations of the 200 teenagers in his school class and thousands of others across the country, translated into language that bankers would understand.
"Most teens would say the same things," he said. "We talk about this kind of thing at school quite a lot. Though the way we talk about it you probably wouldn't understand it."
