According to Nielsen, 2,804,826 adults tune in to their favorite Detroit radio stations every week. This is significantly more consumers than are reached by all other advertising-supported media, including local TV, local cable, streaming video, social media, online audio, and local newspapers.

Detroit radio's unchallenged reach is why many local business owners depend on the medium to capture the largest possible share of the $88.4 billion dollars consumers are expected to spend at retail this year.

Other local small business owners, however, may be surprised to learn that by most marketing metrics, radio remains the best way to advertise in Detroit.

Here are four more facts about AM/FM radio that may surprise many local marketers.

Based on projections from the National Retail Federation (NRF), Southeast Michigan consumers are on track to spend $63-billion with retailers by the end of this year. This would be 13.5% higher than was spent in 2020.

Since 1920 when WWJ-AM signed on, Southeast Michigan small business owners have been advertising on Detroit radio to market the goods and services they sell.

Lately, some of these advertisers are voicing concerns, though, that the accelerating use of smart speakers could erode the effectiveness of commercials on local stations. Current research, however, reveals that these devices actually extend the reach of the medium and its ad content.

More than 993,674 consumers in Detroit have a smart speaker in their homes, according to Nielsen. This is 30.4% of the local adult population.

Smart speakers are internet-enabled devices controlled by spoken commands and capable of streaming audio content, relaying information, and communicating with other devices. 

According to the Cooperative Institutional Research Program (CIRP) data, Amazon Echo (aka Alexa) accounts for 69% of all smart speakers in use. Google's smart speaker makes up another 20% of the market. The remaining 11% of the market comprises Apple Home (aka Siri), Sonos, and Bose.

Detroit consumers can use their smart speakers to accomplish a diverse range of tasks, including accessing news, weather, and sports information; turning on lights in the house; shopping; and food delivery.

The most common use of a smart speaker, though, is streaming audio, including Detroit radio stations, according to eMarketer. Edison Research's Share of Ear Study indicates that consumers devote 13% of their total time using a smart speaker listening to AM/FM radio stations. This is second only to the time spent listening to Amazon Music at 19%.
