"Dina got her PhD at MIT’s Sloan School a decade ago, before she started teach at Yale. Her thesis looked at TV shows being talked about in the social media of that time, newsgroups, IRC, Usenet, etc, etc. What she and her colleagues found out was that volume (number of mentions) was not a good predictor of popularity. Volume was more of a trailing indicator than a leading indicator. But Disperson, or what Dina calls Entropy, turned out to be a very reliable leading indicator of popularlity of a TV show. The wider and broader the discussion of the TV show went within online social media, the more likely the show was to become popular."
