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:
“Piles of scrapbooks, the cuttings turned by time to the colour of the freckles on an old lady’s hand. Her hand. My hand, as it is now. When you touch the old newsprint, it turns into brown dust, like the dust of bones.”
—Angela Carter (1940–1992)
“The easiest period in a crisis situation is actually the battle itself. The most difficult is the period of indecision—whether to fight or run away. And the most dangerous period is the aftermath. It is then, with all his resources spent and his guard down, that an individual must watch out for dulled reactions and faulty judgment.”
—Richard M. Nixon (1913–1995)
“Teach me half the gladness
That thy brain must know,
Such harmonious madness
From my lips would flow,
The world should listen then, as I am listening now.”
—Percy Bysshe Shelley (1792–1822)
