I'll just add something, for a second, and then I'll go back to your question.
Of course it is elitist to say that the leaders of opinion are listening to or watching CBC. I know this is elitist. But it is very important in every country in the world to have what are called “quality” newspapers--usually it's the newspapers that play this role--like the New York Times, or Le Monde in France, or the Guardian in Great Britain. Political leaders, civil servants, business leaders are kept informed through those quality papers.
In English Canada, hopefully, there's one, the Globe and Mail. On the French side, there are good papers, but not something similar to the Globe and Mail, which is a world-quality newspaper. I've always felt that CBC radio on the French side is playing this role of quality media.
To go back to your question, when we are talking about 5%, this is the audience share. There is another matter to look at in terms of audience. It's what we call reach--how many people over a week listen to the CBC? Of course, I use the figure of 5% or 6%, and this is not much. But if you look at the general population, which is your preoccupation, how many? I don't have the figures with me, but how many people are listening to CBC radio or watching CBC television once or twice a week ? That would be a better approach for evaluating public radio or public television.
