According to Nielsen, 3,740,743 adults tune in to their favorite Philadelphia 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.

Philadelphia radio's unchallenged reach is why many local business owners depend on the medium to capture the largest possible share of the $108 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 Philadelphia.

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

Philadelphia radio reaches more local consumers each week than any other advertising medium.

According to Nielsen, 3,740,743 adults tune in to their favorite AM/FM stations every week.  This is significantly more consumers than are reached by Philadelphia TV, cable, streaming video, streaming audio, social media, or newspapers.

AM/FM radio's dominance among local consumers is driven, in large part, by the 3.8 million Philadelphia-area adults who take to the road in their car or truck every week, according to Neilsen.

Every week, according to new Nielsen data, 3,667,169 adults tune in to a Philadelphia radio station. This is more consumers than use social media, access local cable, watch broadcast TV, stream video channels, listen to streaming audio, read a newspaper, or download a podcast.

Based on per capita estimates from the National Retail Federation (NRF), Philadelphia consumers are expected to spend between $83.2 and $84.8 billion at retail in 2022, a six to eight percent growth over the previous year. Utilizing radio's enormous advertising reach, local business owners can compel shoppers to spend this large pool of cash in their stores and on their websites.

The number of consumers reached is critical to the success of an advertising campaign.

According to a Nielsen study, after the actual content of the commercial message itself, reach is the most potent advertising element that can drive sales. Reach is more important than brand, recency, or even context. Philadelphia radio provides local business owners with the most significant reach among consumers.

There are about 3,500,000 registered passenger vehicles in the Philadelphia area. Some are cars. Some are trucks. Some are Hondas. Some are Fords. Some are Teslas. Some have four doors. Some have two. Some go fast. Some go slow. Some guzzle gas. Some sip. Some are red. Some are blue.

The one thing that almost every car and truck in the Philadelphia area have in common, though, is the AM/FM radio smack-dab in the middle of the dashboard.

The first car radio went on sale in 1930. It was an invention of the Galvin Manufacturing Company. The company named the radio 'Motorola,' and its cost was $130, around $2000 in today's dollars. By 1935, more than three million car radios had been installed.

Today, AM/FM radio is part of every car and truck on Philadelphia area roads. In addition to the radio, many of these vehicles also provide drivers with other audio options, including a CD player, Sirius/XM, Pandora, Spotify, podcasts, and easy access to personal MP3 collections.

It is fair, then, for small business owners who depend on Philadelphia radio to advertise their goods and services to ask: with all the audio options on today's dashboards, is anyone listening to local AM/FM radio in the car anymore?
