Sorry. I'm not taking this personally. But the linked article itself is worthless because it uses words without setting forth what they mean.
Hey Biz, I'm just seeing these. Let me take a shot at answering them to the best that I can.
The original graphic is from a tweet by Storrs South. As you point out, the terms are undefined. As you probably know, the term "brand value" is it a measure of which people perceive a particular item. In essence you net out the positive reactions and the negative reactions and you come up with a "brand value" figure. This particular metric is labeled as "TV brand value" so, it would appear to be a metric defining the way TV viewers view Connecticut in the Big East. Clearly, it's not "ratings" alone, otherwise Nielsen would use that term. So, my best guess is that the "TV brand value" metric, is a comparison of how Connecticut, in particular, and the Big East in general, are perceived versus other competing sports viewing alternatives. But that's just speculation on my part, assigning reasonable definitions to the words provided.
Sure, it would be helpful to have a detailed description of how the "TV brand value" metric is derived, but as with most things found on Twitter, there aren't a whole lot of descriptive footnotes. If you decide you're curious and want to Google it, feel free to post it here. I would be interested in seeing what the details of the metric actually are.
