11.16.15 - 11.22.15 Numbers Thread

Happy, it just hasn't shown up on any lists for Canada yet. The Canada lists are not as easy to access. For instance, I don't think they have a spin increase chart for us to see.  :( 

Just one minor technical correction to this part of the above excellent post...

"Audience Impression is in millions. It is determined by the Nielsen ratings of the stations in a certain city. In the US, NY is #1, LA is #2, Chicago is #3, etc. Audience is weighted by time of day the song is played. A spin at Noon is better than a spin at 3 a.m".

There is no weighting involved in Audience Impressions.

Should be:

Audience Impressions (AI) are in millions. It is the total of estimated number of people who had the opportunity to hear the song every time a radio station that played the song. For Mediabase it is calculated by multiplying the average Nielsen rating for the radio station during the time segment (Daypart) when the song was played times the market's total radio audience. 

There is no weighting involved. Ratio audience sizes are estimated based on the average rating for specific time period using the Average Quarter-Hour Persons estimate (the average number of persons listening to a particular station for at least five minutes during a 15-minute period) as recorded by Nielsen. For Mediabase AI they use a grand average of these measurements for a larger time segment.

Dayparts used for Radio ratings are the time segments typically used in programming and by advertisers.

ovn = Overnight 12-6 am
am = Morning drive 6–10 am - this is radio's Prime time (most listeners)
mid = Midday 10 am - 3 pm
pm = Afternoon drive 3–7 pm - this is radio's 2nd Prime (second most listeners)
eve = Evening 7pm-12am

The markets used in US local radio are MSA or Metro (Metro Survey Area) are determined by Nielsen Media Services. The Metro Survey Area usually includes the cities of license for the majority of the local radio stations and the counties where these cities are located. About half of the radio Metros correspond to the federal government’s market definitions (Metropolitan Statistical Areas); the other half deviate in some way from the government MSAs. These exceptions were made to take into account such factors as historical market definitions, local trade and commuting patterns and local radio listening patterns.

Markets are ranked by total audience size - #1 New York, #2 Los Angeles, #3 Chicago, etc. The market size is related to Audience Impressions (AI) only because it is used to convert the sample ratings data into a total audience size. A radio station in NYC with low ratings could have a smaller audience that a radio station with high ratings in a large market.

Without making this a very technical and very long post, when you put it all together, the Mediabase AI is a somewhat loose estimate of audience size.

Glad to see ALN doing so well!! If it moves up on HAC and POP, hopefully it will trigger Christmas sales!!! Go ALN!!!

I am confused. What did I say thst was different?
AI in millions - check
Nielsen rating -check
Time of day - check
???

ETA: Billboard uses AI as part if their Hot 100 formula! It is very important!
