The need for regional programming and regional content has been well proved in the news sector of the CBC. When they had the massive cutbacks, of course there became far more of a national focus to the news programming. I do believe they've switched back to a more regional focus now, having failed in that experiment. That has proven to be a worthwhile venture for the CBC in terms of listenership and people watching, and I believe it's a sound model that can be applied to drama as well.
