I’ve been saving ratings data for over thirty years. Below are two charts of noncommercial
stations in Los Angeles – the most recent Nielsen Audio report from 2014 and an
Arbitron report from 2000.
NOTE: These two charts represent different methodologies and
can NOT be compared statistically. Here are big picture trends:
KEN’S ANALYSIS:
• KCRW has the
same AQH Share and Weekly Cume but it had twice as many Metro AQH Persons in
2000. Reasons: People using radio has
declined since 2000; Time Spent Listening has also declined over 14 years.
• KKJZ was KLON
in 2000. Listening has declined somewhat
but remains strong.
• KPCC’s listening
has changed a lot. Fall 2000 was before American Public Media took over took
over KPCC via a Local Marketing Agreement. The AQH Share and Weekly Cume have
more than doubled over 14 years. Great job folks!
• KPFK’s listening
has severely declined since 2000. KPFK’s AQH Persons in 2000 were three times
larger than 2014; Weekly Cume was more than twice as big in 2014. In my opinion, Pacifica’s dysfunctional
management and governance is an embarrassment to all of us who work in public
media.
• KUSC has
significantly more listening in 2014 than 2000.
One reason for the increased listening to KUSC is the departure of commercial
classical station KKGO-FM since 2000.
