Time Spent Listening

Time spent listening (TSL) is one of the measurements surveyed by Arbitron in determining ratings for radio stations in the U.S.. The TSL is the amount of time the average listener surveyed spent listening to each radio station at one time, before changing the station or turning it off.

The TSL is an estimate of how long the average panelist (listener) was exposed to a particular station or stations for a specific time period.

It is the equivalent of Average Time Exposed (ATE), Daily or Weekly.

TSL trends are helpful in determining if programming decisions are having an effect on the audience.

Famous quotes containing the words time, spent and/or listening:

    Words, words, words! They shut one off from the universe. Three quarters of the time one’s never in contact with things, only with the beastly words that stand for them.
    Aldous Huxley (1894–1963)

    No contact with savage Indian tribes has ever daunted me more than the morning I spent with an old lady swathed in woolies who compared herself to a rotten herring encased in a block of ice.
    Claude Lévi-Strauss (b. 1908)

    Lift every voice and sing till earth and heaven ring,
    ring with the harmonies of liberty.
    Let our rejoicing rise high as the listening skies;
    Let it resound loud as the rolling sea.
    James Weldon Johnson (1871–1938)
