CBC-TV has a new chief programmer, and she has a theory about programming: read the metrics right and you can choose the shows. ” ‘If a show scored 7.6 out of 10 and that ended up bringing in an audience of x-hundred thousand, I can build models on that that I couldn’t with qualitative research.’ Which is great if you want the trains to run on time backwards but not very useful if you’re trying to engage viewers forwards.
