What is “Hour Exposure?” posted on July 1st, 2019
By Paul Ziino
Head to Dataset/Analysis/Turnover Analysis. Once it loads in the upper half of the screen you’ll see all your categories and a number of columns. You can add and subtract columns by right-clicking in that upper half and checking additional columns. The column we’re discussing today is “Hour Exposure.”
Hour Exposure is the percent of hours a song from that category will play in before repeating in an hour. The highest number you will see is 95.83% which indicates a song is predicted to play in all hours before repeating in one of them. The lower the percent, the fewer the hours the song will hit before repeating in an hour.
If you have a category that doesn’t play 24/7 its Hour Exposure percent will drop. If category X only plays from 6pm-6am, that eliminates 50% of the hours, so the highest score you’ll see is 45.83%. If the category is only played in 6 hours of the 24 hour broadcast day, the highest hour exposure possible will be 20.83%.
When we are using Turnover Analysis to look at predicted rotations, we’re looking to maximize the Hour Exposure, without causing stacking in the predicted play rotation. Looking at Category A we have a 45.83% hour exposure. We do see some stacking in the predicted play history.
If we adjust the slot count up and down we can see how this will change not only the Hour Exposure, but also the predicted rotation.
In this example, not only is the Hour Exposure lower, but the predicted rotation is pretty rotten, too.
Following is an example where we get that stairstep but still have a low Hour Exposure. That’s because the rotation is predicted to hit the same six hours over and over.
Add three more songs to the category and your Hour Exposure jumps to the perfect 95.83%.
