Since the adoption of the PPM in most of the top 100 markets, we know that diary entries don't always reflect the whole truth. What's the percentage of non-vehicle listening in PPM markets?
The PPM is in 48 of the top 51 markets. There are absolutely no plans, due to cost, of extending it to smaller markets.
There is no "non-vehicle" PPM data. PPM has "at home" and "away". "Away" includes any location out of the home, such as in a car, at work, in a park, etc. The PPM has no way of knowing if it is in a car or other vehicle, specifically.
How are these ratings respondents listening to radio at home and work if no one's buying radios? Devices other than radios?
The PUR (Persons using radio) which used to approach 20 (meaning 20% of people on average were listening to the radio) is now down in the 6 to 8 zone in most PPM markets. That means that due to the greater precision of the PPM and the reduced listening to radio, the levels are off by about two-thirds.
Part is due to people using alternatives, including conventional streaming, telling Alexa to play music, or paid services.
Device listening is counted as streaming in PPM markets (different encoding than the over-the-air signal). We see the ratings for some stations' streams in PPM markets, but they're minuscule.
The problem here is that a lot of streaming listening is done with ear buds and the like, and is not picked up by the PPM.
