according to the nielsen folks
www.nielsenmedia.com/ There are four sets of data collected by nielsen folk from 210 TV markets on 106,641,910 TV Homes containing a bit over 270 million tv viewers age 2+
(this means about 2.5 individuals per tv household)
___
This means
National Nielsens have 5000 HH's and 13000 individuals or 2.6 people per HH
National ratings - Buffy is only drawing 3% of the 5000 national tv nielsen families - or - 150 tv households
2.6 people per household X 150 HH = 390 nielsen people watching
390 /270,000,000 US tv watchers = 1 in 692,308 people is in a nielsen family and watching buffy
or statisticly speaking - each of the 2400 people on this board would have to screen 289 people before we would collectively find one who was a nielsen family buffy watcher
Bottom line - unless we were VERY lucky - probably not the best use of our time/effort
on the other hand - UPN got 1.2 million unique hits to its buffy site the day it opened -- so better than 20% of buffy's viewership is on line and works the web for buffy info - thus shaping the "buzz" about the show via posting on the major buffy boards IS a way to effect the public attitude about the show and thus perhaps its ratings...although I will be the first to admit - I post here because I find other boards much less to my tastes/tolerance

NOTE:
1) the NATIONAL Data is collected by meters on 5000 tv house households (out of 106,641,910 total US households with TV's) containing a total of 13,000 individuals
what is being watched by whom is measured (according the the nielsen website) by an electronic measurement system called the Nielsen People Meter. "These meters are placed in a sample of 5,000 households (13,000 persons) in the U.S., randomly selected and recruited by Nielsen Media. The People Meter is placed on each TV in the sample household. The meter measures two things - what program or channel is being tuned and who is watching"
so
13,000/270,000,000 ---or --- [1 in 20,769] people is part of the National Nielsen data base
2) The METER MARKET numbers
(400-500 HH/market) X (55 markets) = 22,000 to 27,500 tv households
22,000 HH's X 2.5 people per HH = 55,000 people
or
55,000/270,000,000 ---or--- [1 in 4909] people is part of the Metered Market Nielsen data base
In 55 largest markets in the U.S. - "a different metering system provides TV ratings information on a daily basis."
"In each of the metered markets approximately 400-500 households are recruited (not the same homes as the national People Meter sample), and electronic meters are attached to each TV set in the sample home. Homes recruited for local samples are not equipped with People Meters, so the information is limited to "set tuning" information from which Nielsen Media Research can determine which channel the TV set is tuned."
"This information is used by local television stations, local cable systems, advertisers and their agencies to make programming decisions as well as to buy and sell commercial advertising."
3) SWEEPS DIARY's
"nearly 1.6 million diaries are edited each year."
"demographic viewing data (from all 210 tv markets during sweeps) which are collected from separate samples of households which each maintain a paper viewing diary for one week."
4) HISPANIC DATA
approximately 1,000 metered homes for national and local Hispanic measurement
