Radio advertising in Chicago: on air and online

On-air and online radio advertising in Chicago: what each one is

Radio advertising means paying to have a short audio message, usually called a spot or a commercial, play inside audio that people already listen to. It comes in two forms. On air means a broadcast station plays the spot over its AM or FM signal. Online means the spot plays inside an internet stream: a station's own stream, a streaming radio service or an internet radio channel. A plan often uses both.

We handle both forms with one team. Media Express LLC writes scripts in English and Polish, provides voice talent and production, places and negotiates radio commercials on Chicago-area Polish and English stations, runs online streaming radio ads and operates its own Polish radio network with 6 HI-RES streaming channels (PolskieRadio.us and polish.network). We work with every budget, we do not publish prices, and scope and cost come in writing after a short call.

The two forms overlap in real listening. In Edison Research's Infinite Dial 2026 (a January 2026 survey of 2,050 people aged 12 and older), 81% of Americans listened to online audio in the past month. Edison's analysis at SSRS found that 30% of weekly radio listeners listened to a stream for at least part of their radio time, while 70% listened only to traditional AM/FM.^[14],[15]

Broadcast radio has a large reach of its own. Nielsen reports that radio reaches 92% of U.S. adults every month, and in its Fall 2025 market list Chicago is the third-ranked radio market by population, with an estimated 8,202,000 people aged 12 and older. The Edison and Nielsen figures come from different studies and age groups (12 and older versus 18 and older), so do not add them up or rank one against the other.^[17],[18]

Polish radio advertising: who you reach and in which language

Polish-language radio serves a specific audience, and Chicago is where it is concentrated. The Census Bureau's American Community Survey (ACS) is a sample survey, so every figure below is an estimate with a published margin of error. These are the 2024 one-year estimates for ancestry (table B04006) and language spoken at home (table B16001).^[11],[12]

Sources: ^[11],[12]

Polish ancestry is common: the Census Bureau's 2023 Polish-American Heritage Month story, using 2022 data, ranked it the sixth most-reported ancestry in the United States, and our reading of the 2024 table puts it in the same place among named groups. Polish as a language spoken at home is far more concentrated. By our own arithmetic from these estimates (the margins of error make them approximate), the Chicago metro area holds about three in ten of the people in the United States who speak Polish at home, against about one in twelve of the people who report Polish ancestry.^{[11],[12],[13]}

About two in five of the Polish speakers in the Chicago area (66,092 of 158,687) told the survey they speak English less than "very well". For those customers an English-only spot does not carry the message. That is the practical case for Polish-language radio: not heritage in general, but customers who decide in Polish.^[12]

What the Census cannot tell you is whether your customers listen to Polish radio, which station they prefer, or whether radio moves them more than a search or a friend's recommendation. It counts people, not listeners. Station audience comes from the station's ratings and, more reliably for a small business, from tracking your own responses.

We write the Polish version as its own script, not as a word-for-word translation of the English one, and we place Polish-language spots on Chicago-area Polish stations and on the streaming channels of our own network. Our page Polish advertising agency in Chicago on mediaexpress.us describes the wider service.

How a radio campaign is built with us, from brief to report

Work starts with a request, a short call and a written scope: the goal, the channels, who approves what and the success measure. We start from the budget you have and show what it can and cannot reach before anything is produced or booked. A person approves what goes live. AI helps us work faster on drafts, script variants and checks.

1. Objective and audience

   One goal: phone calls, store visits, form leads or an event. Then who you want to reach, where, in which language and at what time of day.

2. Script

   One idea per spot, written in English, in Polish or as two separate versions, and read aloud for timing. You approve it before anything is recorded.

3. Voice and production

   Voice talent, recording, music and sound effects, and finished files in the lengths the stations or platforms ask for. You approve the finished spot.

4. Placement and negotiation

   We approach the stations that fit the audience, negotiate the schedule and put days, hours and makegood terms in writing. Online placements get the same written terms.

5. Flight and frequency

   We set the weeks on air, the spots per week and the mix of dayparts against your budget, and say plainly how much of each station's audience that schedule is likely to reach.

6. Tracking set-up

   A dedicated phone number, a short web address or landing page and a promo code for each spot or station, so responses can be told apart.

7. Launch, monitoring and report

   We check that the spots aired as ordered, record calls and codes, and report in plain English what ran and what came back. Then we adjust the next flight.

• We do: scripts, voices, production, planning, placement and negotiation, tracking set-up and reporting.
• You approve: the goal, the script, the finished spot, the schedule, and any offer or claim in the copy.
• The station or platform controls: which spots it accepts, where in the break a spot runs, and whether a pre-empted spot is made good. The RAB glossary defines a makegood as comparable commercial time at no additional cost when a spot is pre-empted, omitted or airs in an unfit condition, so the contract should say how it works.^[19]

Spot lengths, dayparts, flights and frequency, for every budget

Most commercials are written for 60 or 30 seconds, according to the Radio Advertising Bureau's (RAB) copywriting guide, and shorter spots are sold too: a study by Cumulus Media Westwood One and the RAB says 15-second ads generally cost about half as much as 60-second ones. The guide's practical test is to read the copy aloud at a normal pace. If that takes 75 seconds, a 60-second slot will not hold it.^[21],[22]

Time is sold by daypart. In the RAB glossary, using Nielsen's usual definitions, morning drive runs Monday to Friday from 6 AM to 10 AM, midday from 10 AM to 3 PM, afternoon drive from 3 PM to 7 PM, evening from 7 PM to midnight and overnight from midnight to 6 AM. A station's own dayparts may differ, so the contract should state the exact hours. A flight is a schedule that alternates weeks on air with weeks off. Reach is the number of different people who hear a campaign, and frequency is the average number of times the same person hears it.^[19]

Sources: ^[22]

Read that table with two cautions. It comes from a seller-side study (a radio network and the radio trade association, using Nielsen figures) and describes a typical station, so Chicago stations will differ. It also shows why thin schedules disappoint: in the same study, a count of one week in August 2020 found that 73% of the schedules examined were at the very light level and only 2% reached the heavy level. The study itself says not to expect grand-opening results from a light weekly campaign.^[22]

What a smaller budget can do:

• Concentrate. One station or one network and a few strong weeks usually say more than the same money thinly spread across many stations.^[22]
• Shorten the spot. At about half the cost of a 60-second ad (the sellers' statement above), a 15-second ad lets a fixed budget buy more airings. It carries one idea only.^[22]
• Mix dayparts. The study also says nights and weekends generally cost about half as much as drive time. Those hours reach different people, so match them to the customer you want.^[22]
• Pair on air with online. Streaming ads can run in weeks when the on-air flight is off. We set the split in the written scope.
• Get the terms in writing: exact daypart hours, makegood terms, cancellation terms and a record of when each spot aired. The RAB glossary defines discrepancy, makegood and cancellation policy as separate terms, so settle each one.^[19]

We do not publish prices. The estimate is free, we work with every budget, and scope and cost come in writing after a short call.

Radio commercials: scripts, voices, music and bilingual creative

A radio commercial does one job and has only seconds to do it. The RAB's creative guidance (January 2024) says to name the brand early and often, tell a story, keep the tone consistent and sound local. It cites Nielsen brand-effect studies in which one or two brand mentions produced 59% brand recall and seven or more raised it to as much as 77%. The RAB is the industry's trade association, so read those figures as an industry view. The practical point stands: name the business early.^[20]

• One idea

  One idea, one offer and one way to respond (a phone number or a short web address) is easier to hear, remember and measure than a spot that says everything. The RAB's copy guide tells writers to limit the big idea to one per spot.

• English, Polish or both

  Each language is written as its own script. A Polish spot should sound natural in Polish, not like a translation, and an English spot keeps its own rhythm.

• Voice and tone

  We provide the voice talent and the production. The RAB's guidance favors a real, conversational voice over a stage "radio voice", and a voice and sound that stay consistent across a campaign.

• Terms and claims

  Offer terms and legal wording take airtime too, so they belong in the first draft. The RAB's research summary says disclaimers are not a turn-off for listeners who are ready to buy.

Clear the music before production. The RAB's copy guide notes that copyrighted music a station plays may not be used in an advertiser's recorded commercial unless the advertiser pays the rights holder, and it recommends sound-alike or royalty-free production music instead. Use licensed production music or music you own.^[21]

Bilingual does not mean one script spoken twice. Choose by audience: an English spot for general listeners, a Polish spot for Polish stations and, where one station serves both, a spot that is mostly in one language with a short line in the other. Keep the offer, phone number and web address identical so responses can be compared, and keep the terms in the language of the spot. An example in the FTC's Endorsement Guides (16 CFR 255.0, Example 11) says that when an ad is microtargeted in a foreign language to people who cannot understand English, a required disclosure must be in the same language as the ad. It concerns endorsements, but it is a sound rule for any bilingual spot.^[4]

FCC, FTC and Illinois rules for radio commercials

Sources: ^[1],[2],[3]

The FTC and Illinois rules apply to what a spot says, on air and online alike:

• FTC truth in advertising. An ad must be truthful, not misleading and, when appropriate, backed by scientific evidence, whether it runs on the Internet, radio or television, and the FTC applies the same standards wherever an ad appears. The FTC's 1984 substantiation policy statement says advertisers and ad agencies need a reasonable basis for a claim before it is disseminated, and its small-business guide defines that basis as objective evidence. We ask for the evidence behind a claim before we write it.^[5],[6],[7]
• Honest endorsements and audible disclosures (16 CFR 255). An endorsement must reflect the endorser's honest opinion or experience, an unexpected material connection must be disclosed clearly and conspicuously, and an audible disclosure should be delivered in a volume, speed and cadence that ordinary consumers can easily hear and understand. Fast, quiet small print at the end of a spot may not meet that test.^[4]
• Illinois (815 ILCS 505/2 and 510/2). Deceptive acts or practices in trade or commerce are unlawful whether or not anyone was in fact misled, and courts are told to consider FTC interpretations. The deceptive trade practices list includes advertising goods or services with intent not to sell them as advertised, advertising with intent not to supply reasonably expectable public demand unless the ad discloses a limit on quantity, and false statements about price reductions. A radio sale needs stock and prices that match the spot.^[8],[9]

Online-only audio sits outside the broadcast station rules as the FCC's guide describes them, since the guide says they apply to program material aired over broadcast radio and television stations. That does not make it rule-free: the FTC's rules reach ads on the Internet, and each platform publishes its own ad policy, which you should read before the spot runs there.^[2],[5]

Measuring a radio campaign: phone numbers, web addresses, promo codes and honest limits

Before a spot airs we set up a way to tell responses apart: a dedicated phone number, a short web address or landing page, and a promo code for each spot, station or platform. The RAB glossary defines direct response advertising as advertising with a built-in call to action that asks for a response within a defined period, and lists phone calls, online orders and visits to a location as examples.^[19]

The limits to know before you judge a campaign:

• Station audiences are estimates from samples. In the 48 largest markets Nielsen uses a wearable meter panel and in more than 200 other markets it uses diaries. Counting rules change the result: Nielsen says a three-minute listening qualifier, in use since January 2025, raised measured average audience by 24% on average.^[18]
• A station rating is not a spot rating. A station's audience in a time period is not a count of the people who heard your spot. Nielsen's own advice to advertisers is to use as-run data, not planned ratings points, because planned points can differ significantly from what was delivered.^[16]
• Online counts show delivery, not attention. The Media Rating Council definition counts audio ads from client-side activity records, leaves out ads played while the player is known to be muted and defines an audible impression as an ad audible for at least two continuous seconds.^[23]
• Some responses cannot be traced. A listener may hear a spot and call a week later without a code. A rise in calls, direct visits or searches for your name after a flight is a clue, not proof.
• We promise no result. We report what ran and what came back, and we say so when the data are too thin to judge.

Radio works best as one part of a plan. Here is how it connects to your other channels:

• Website and landing page

  A fast, clear page behind the address in the spot turns a visit into a call or a form. CMS MESH 5.1 (Media Express Static Hub), our own new-generation manual CMS, makes ultra-fast static HTML pages with no database and no plugins to update. See web design and CMS MESH.

• Search

  Some listeners search for your name instead of using the number. Make sure it leads to a correct listing and a matching page. See AI search and local SEO.

• Paid search and social

  Paid ads can repeat the offer to people who heard the spot. See our advertising agency page.

• Email, SMS and social posts

  The same offer and promo code can run in newsletters and posts. See our marketing agency page.

When radio advertising is NOT a good fit

• You need leads from this week's searches. If people already search for your service, search ads reach them at the moment they ask. Radio builds familiarity and sends people to you. See our advertising agency page.
• You cannot answer the phone or the web form quickly. A radio spot drives calls and visits, and an unanswered response wastes the airtime.
• The budget buys only a very light schedule on many stations. The industry study above found that most schedules reach only about a third of a station's audience, about one and a half times each. We would rather advise a narrower plan, a shorter spot or another channel than spread the money thin.^[22]
• Your offer cannot be said as one idea. Complex terms, long lists and dense legal details are hard to take in from one hearing. Use the web, print or video for the details and use radio to send people there.
• You cannot support the claim. FTC and Illinois rules put the burden on the advertiser, and we will not write a claim you cannot back.
• You need every sale tied to a click. Radio cannot give click-level attribution, as the measurement section explains.
• You want a promised result. No honest seller of media time can promise one.

If one of these fits, we will say so on the first call.

What to prepare before we talk

• The goal in one sentence, and how you will count success: calls, visits, form leads or sales.
• Your offer, your service area and your hours, and who answers the phone and in which language.
• Your best customers, and whether they decide in Polish, in English or in both.
• A budget range, even a rough one. We start from it and say what it can and cannot reach.
• Any claim you want to make and the evidence behind it: licenses, years in business, awards, prices and stock.
• Music or brand sounds you own or have licensed, and any earlier scripts or spots.
• A web address and phone number that can be tracked, or your permission for us to set up new ones, and the name of the person who approves scripts and finished spots.
