AM/FM radio advertising generates significant sales and profit growth reports Peter Field, “godfather of marketing effectiveness”
Peter Field’s latest blockbuster study is called The Long and the Short of It – 10 Years On: Radio’s Enduring Role in Effectiveness. This consequential new study lays out hard evidence for how AM/FM radio drives significant lifts in market share, pricing power, sales, profits, and ROI.
Field analyzed the Institute of Practitioners in Advertising (IPA) databank of over 1,200 case studies submitted to their Effectiveness Awards Competition. Covering a broad spectrum of marketing categories and budgets, they “represent the most rigorous proofs of the effectiveness of marketing communications in the world.” Field compared the business outcomes of marketers who have AM/FM radio in their media plans to those that do not use AM/FM radio advertising.
AM/FM radio boosts mental availability (the propensity of a brand to be noticed and thought of in buying situations) by +13%

In their book 66 Ways To Screw It Up: How Not to Plan, Les Binet and Sarah Carter explain:
“The single most important factor driving brand preference is ‘mental availability’: how well known a brand is, and how easily it comes to mind. Brands with low mental availability tend to struggle, rejected in favour of more familiar rivals. Or not considered in the first place. Brands with high mental availability don’t have to push so hard to sell, so tend to have higher market shares and better margins.”
Field’s research found that marketers that used AM/FM radio had +13% greater mental availability than brands that did not use AM/FM radio.
Media plans with AM/FM radio have +28% greater market share than brands that do not use AM/FM radio
From 2000 to 2022, brands in the IPA databank using AM/FM radio had a +28% greater market share (32%) compared to brands not using AM/FM radio (25%).

Pricing power is the biggest profit driver; Brands cannot thrive just by selling more
Peter Field’s analysis of the IPA databank reveals that pricing power is the biggest profit driver:
- 46% of brands with market share increases report large profit gains.
- 56% of marketers with pricing power have very large profit growth.
- 75% of brands with both market share gains and pricing power have very large profit growth.
Field notes businesses cannot thrive just by growing sales volume. Pricing power is a key profit accelerator.

Warren Buffett has made a career of investing in companies with strong brands. Companies with strong brands recover faster from uncertain economies and have greater consumer purchase intent.
AM/FM radio improves brand pricing power by +17%
Compared to brands not using AM/FM radio, Field reports advertisers using AM/FM radio enjoy +17% greater pricing power, a key profit driver.

Advertisers using AM/FM radio have +42% greater profit than brands that do not use AM/FM radio

AM/FM radio’s impact on profit growth is increasing
Since 2016, Peter Field’s analysis of the IPA databank reveals the profit uplifts among marketers who use AM/FM radio versus those who do not have been growing steadily.

Brands using AM/FM radio experience +23% greater return on marketing spend
Compared to brands who don’t use AM/FM radio, AM/FM radio advertisers experience +23% greater return on advertising spend (ROI).

Peter’s Field’s new study makes a decisive business case for AM/FM radio advertising.
Nielsen: AM/FM radio generates impressive $10 return on advertising across a wide variety of categories
Nielsen has conducted dozens of AM/FM radio sales effect studies by matching Portable People Meter AM/FM radio ad exposures to retail purchases from credit and debit cards and consumer packaged goods sales via grocery shopper card data. Averaging all of the studies yields a $10.59 return on AM/FM radio advertising spend.

The figures above represent incremental sales generated by a dollar of AM/FM radio advertising. For example, Nielsen reports a dollar of AM/FM radio advertising for an auto aftermarket retailer drove $17 of incremental sales.

Nielsen Media Mix Modeling: “Radio consistently ranks as a top tier medium for ROI”
Nielsen recently released the results of a major media mix modeling analysis of 2,857 national, local, and international campaigns across advertiser categories where the allocation to AM/FM radio averaged a notable percentage of the total media budget.
Dave Hohman, EVP & GM Global Marketing Effectiveness at Nielsen’s Media Mix Modeling practice, concludes: “When the relative weight of impressions is large enough to be measured, radio consistently ranks as a top-tier medium for ROI. Streaming audio also performs well, albeit behind broadcast radio.”
Ebiquity/Gain Theory: Of ten media, audio is number two in short term ROI and number three in long term ROI
Profit Ability 2: The New Business Case for Advertising is a significant recent study on marketing effectiveness from measurement firms Gain Theory and Ebiquity, along with media agencies EssenceMediacom, Mindshare, and Wavemaker UK. The study was a massive undertaking that involved analyzing $2.2 billion in media spend (2021-2023) across 142 brands, 14 sectors, and 10 media channels.
The study revealed audio has the second highest short-term return on advertising spend (within one to thirteen weeks). Audio ranks third in overall return on advertising spend (week one to two years).
A dollar invested in audio (AM/FM radio, podcasts, or streaming) would generate $3.12 of profit within one to thirteen weeks. Overall, a dollar invested in audio will return $6.29 of profit over the entire two-year period (one week to two years).

How advertising really works: Steve’s Pest Control of Columbia, Missouri used AM/FM radio to build a huge business
1,095 miles to the west of New York City lies Columbia, Missouri, the home of Steve’s Pest Control, “Missouri’s number one choice for pest control.”
Steve’s Pest Control knows what Madison Avenue has forgotten. To generate substantial sales and profit, a business needs to create future demand rather than obsess over short term metrics and only focus on converting existing demand.
