So what does all this crap mean? Here's a quick guide to understanding these numbers:
"Grey's Anatomy" (15.36 million viewers, #2; adults 18-49: 6.0, #1)
15.36 = "Grey's" total viewers, which indicates 15.36 million viewers in the U.S. watched this broadcast
#2 = "Grey's" total viewers ranking for that night (T denotes a tie)
6.0 = "Grey's" adults 18-49 rating, which indicates 6.0% of all adults 18-49 in the U.S. watched this broadcast
#1 = "Grey's" adults 18-49 ranking for that night (T denotes a tie)
Some other stuff to keep in mind:
· For the 2009-10 season, there are an estimated 292,000,000 people (age 2 and above) in the U.S.
· For the 2009-10 season, there are an estimated 132,000,000 adults between the ages of 18 and 49 in the U.S. so 1% of that equals 1,320,000 people.
· Nielsen Media Research forbids us from displaying ratings in chart form or maintaining regular archives beyond the current week. It sucks, we know.
