Canwest has released the results of a study that seeks to measure specialty television channels by quality rather than quantity of ratings. Instead of just pure viewer numbers, it seeks to rank networks by how attentive their viewers are, and how likely they are to pay attention to ads.

A cynic might notice that Canwest-owned networks, including Food Network, HGTV, History Television, Showcase (and its sister networks), National Geographic, Mystery TV and TVtropolis, improve their scores under this measurement. Under pure ratings, only one Canwest network (HGTV) comes in the top five, and only three (with History and Showcase) in the top 10. In the other metrics shown, Canwest networks have 2-3 of the top five and 4-6 of the top 10.

That cynic might wonder if Canwest would have released this study if Canwest-owned networks hadn’t fared so well.
