Sounds like what we have is a choice between:
(1) A valid sample and a notoriously unreliable instrument.
(2) An inadequate sample and a reliable instrument.
Arbitron's monopoly and their continued use of diaries is indefensible. Agencies don't trust Arbitron numbers and so they avoid buying radio. Arbitron gets their feet held to the fire and finally moves toward PPM but early numbers suggest accurate numbers might go against some segments heretofore over-counted. So they play the race card and the industry, as usual, caves in.
No, no and no.
Agencies wanted electronic measurement principally for its fast delivery.
The PPM in NY had bad measurement, period, and the MRC would not certify it... there is talk of reviewing Houston, the only accredited market.
The sample was not adequate in 18-34. It is not proportional within age cells on ethnic balance and language usage... in other words, all the Hispanics that are Spanish dominant could be over 45 and as long as there are the right 12+ number, Arbitron would accept it. The sample has to be proportional in every cell to be a true representation of the universe.
While many broadcasters complained, it was the growing dissatisfaction of ones like Cox and Clear that had the most effect; the real stop on the rollout came from the MRC, though. They simply said the methodology and implementation were not certifiable and Arbitron knows that the MRC, mostly an advertiser and agency orgainization, by withholding accreditation could make the results totally suspect.
The diary is a perfectly useable methodology, even today. In the only accredited market (partly because Arbitron used in home recruitment), the diary and PPM shares are very, very close to each other. Cumes expand in the PPM, but the expansion cume is veeeeeeeeeery light listening, and the P1 and P2 listeners are comparable to the diary in percentage of total listening; all you get is about 50% ot 80% more cume that nearly never listens and is totally unreachable with normal reach and frequency strategies.
The main reason agencies want the meter, beyond immediacy, is that it will allow posting like the metered homes do in the tv world. That will revolutionize radio, and not for the better.
