Nielsen found that online buzz tends to correlate with actual ratings more strongly among younger demos than older demos: for the 50+ cohort, the correlation is low across the board (males, females,
and all persons), 35-49 is somewhat correlated, and the highest correlation between buzz and actual ratings is seen among 12-17-year-olds. I'm guessing that the overall volume of buzz is
higher among the younger demos (although I suppose there could be millions of 50-something women breathlessly posting about Gossip Girl).
