TSL2 said:Time spent listening is down, listeners still like radio but now have more gadgets that take up their time. TSL was 2:45 not it's 1:45. Expect it to continue to decline we haven't hit bottom yet.
I presume you are referring to daily TSL in the diary vs. ATE, or Average Time Exposed in the PPM.
If you are, then you are commiting the sin of comparing two very different methodologies.
If the PPM had existed in 1970, the ATE would have ben 1:45 or 2:00 or something similar. That's because we know that the real PPM measurement of radio listening declines by about 35% in every market from the last diary book to the first PPM book: it is methodology. Of course, if you want to believe that, in perfect synchronization with the PPM roll out listenershop dipped severely from one month to the next, go ahead.
