A 15-year-old schoolboy could have inadvertently decided where media moguls will invest millions of dollars, it has been claimed.

As part of a work experience exercise at Morgan Stanley, Matthew Robson was asked to write a report into how he and friends used media.

But bosses say his document - which detailed use of radio, TV, the internet newspapers and video games - was so good they published it.

They claim to have had a huge amount of feedback about the eight-page report, from fund managers and CEOs who could use it to shape future investments.

Oddly in his report, Matthew did not once mention watching internet porn ... are we really sure he is a 15-year-old boy?
