Every week, according to Nielsen, Detroit radio reaches 2,804,826 adults. This is more consumers than use any other medium, including local TV, local cable, streaming video, social media, online audio, and newspapers.
Reach, though, is only one component used to calculate ratings. The other metric that contributes to the rating formula is the time spent using each medium. So, although for the past 10 years, AM/FM radio's reach has been significantly higher than the reach of local TV, consumers spent considerably more time watching TV. As a result of the math, TV has enjoyed higher ratings than radio.
For the first time, however, AM/FM radio ratings have exceeded local TV ratings by three percent among the key advertising demographic of 18-49-year-olds, according to Nielsen's Total Audience Data for the third quarter of 2023.
In the Detroit area, there are 1,741,591 18-49-year-olds, the majority of whom are millennials, a generation that now accounts for nearly one-third of all retail spending.
