AA rating ABBR. n.
The average percentage of total television households in a given area that
watched a particular program. This is generally calculated as the arithmetic
mean of the fraction of total TV viewing households tuned to a particular
station, sampled once each minute over the course of a program’s broadcast time
slot.
A program’s AA rating is almost always lower than its TA (total
audience) rating due to channel surfing. If they are nearly the same, this
indicates high audience retention (most people who tuned to a particular
program, stayed to watch it). If the AA is significantly lower than the TA,
this indicates low audience retention (a large number of people started to
watch the program, but for some reason then tuned somewhere else).
