If you want to study journalism, you have more choices today, at lower cost, and of higher quality than ever. Sometimes you will get that at a university and sometimes not. That represents a challenge for universities. In a lecture at a journalism conference in Puebla, Mexico, I described a personal experience taking a course in data visualization from one of the world leaders in the field, Alberto Cairo, author of “The Functional Art.” This kind of course represents a major challenge for universities, because their monopoly on expertise and certification is eroding. Just as occurred in the news business, competitors are emerging who are offering attractive alternatives.
