I'm not sure if this is completely relevant to the topic,
and it is certainly out of date, but in July 1968 TV Guide
did an article breaking down the most popular shows by
such measures as geographical area, income, age, and
education. I'd like to see an update with current shows,
but this is what they came up with, based on a six-week
period from October 23 to December 3, 1967 (data from
A.C. Nielsen Co.):
