It takes a teenager to know a teenager, apparently. When Morgan Stanley's European media analysts asked their intern, Matthew Robson, 15, to describe his friends' media habits, his report turned out to be "one of the clearest and most thought-provoking insights we have seen," an executive explained. Robson's report generated five or six times more feedback than usual. The report argued that teens don't use Twitter because it uses up valuable text allowances on mobile phones, that teens eschew traditional radio for ad-free streaming music websites, prefer online or television summaries of the news to the long pages of newspapers, and find it hard to watch regular television.
