Q102 has played "Leavin'" ELEVEN TIMES today! (And it's only 4:00!)

Fakeem said:
I keep seeing the term "TSL". What does it stand for, what is it's function, and why does radio use/need it?

"TSL" means "time spent listening." It's one of the metrics used by Arbitron to measure ratings. Obviously, the higher the number, the better for the radio station. The other chief measure is "cume," which is a count of how many unique people listened (i.e., the "cumulative" number of listeners) during some specified period of time. Cume and TSL are combined to create "AQH rating," which is the percentage of the market population listening during the average quarter hour, and "AQH share," which is the percentage of the people listening to radio during the average quarter hour that are listening to that particular station.

The relevance of TSL to this thread is the theory that heavy repitition reduces TSL (and the counter-theory that CHR stations get their ratings from cume rather than TSL anyway, so it doesn't matter).

Speaking of that, when we see cume numbers posted here at radio-info (from the PPM ratings), are those weekly or monthly cume?
