“Why Shorter Advertisement Breaks Reduce Radio Advertisement Avoidance: When It Comes to Radio Advertising, Less Is More”, 2024-04-02 (; similar):
‘Low-clutter’ radio stations have shorter advertisement breaks to attract listeners, increase advertisement effectiveness, and potentially reduce mechanical advertisement avoidance (ie. switching stations).
This research introduces a two-factor theory explaining why mechanical advertisement avoidance has an inverse U-shaped relationship with advertisement position in the break and advertisement break length in advertisement units.
The theory was supported by portable people meter (PPM) ratings data. Peak mechanical avoidance occurred at the 4th advertisement position, similar to the average advertisement break length perceived by radio listeners from the same city as the PPM data.
This explains why the two-advertisement breaks that are typical for low-clutter radio stations minimize mechanical avoidance.

…Sample: The average monthly PPM panel size for ages 12 and older in the Greater Vancouver area was ~800 individuals. Using census statistics, the authors compared the panel’s demographics with the general population’s demographics, and there were no statistically-significant differences in age or gender.
PPM Data Collection: A PPM device listens for digital watermarks in radio signals and tracks switching between stations, or when the signal disappears, logged as turning off the device. Leaving the room or muting the sound is indistinguishable from turning off, and the authors categorized both behaviors as turning off and, along with changing the station, counted them as forms of “mechanical avoidance.” The official Canadian radio audience measurement data collected using PPM technology by Numeris were made available.
…High-rating stations had a higher proportion of shorter breaks (55% had ≤3 advertisement units), compared with lower rating stations (48% had ≤3 advertisement units) (See Figure 1). These high-rating stations were predominantly “low-clutter” stations, although all stations had advertisement breaks of ≥11 advertisement units.
