In each market area, all listening to any radio station is recorded
by
listeners as is the instruction in the Arbitron diary. Commercial or
non-commercial, local or not, internet or off air, satellite or
terrestrial. All is recorded and processed. If there is any
significant
listening to out of market stations it is recorded.

WRONG. Arbitron does NOT log "ALL LISTENING". They log a small
percentage of listening, and profess to know what all the rest are
doing

Yes. Same way that TV Nielsen Ratings work. Statistics science has
shown you don't need to record everybody..... you can record a small
sample & still get an accurate result of how the group as a whole
thinks.


- While it's true such a process won't record any amount below
- ~0.1 percent of the group, let's face it.... nobody cares about
- such small tiny insignificant numbers.

Actually, it records 0.0 shares based on perhaps one diary mention; the data
is there but all it shows is that in a statistical sample, there is next to
nothing for that particular station. 0 times 0 is 0.
