The Long and the Short of It — Binet & Field's Landmark Report

The Long and the Short of It is Binet and Field's 2013 IPA report that split advertising into short-term activation and long-term brand building. Here's what it found, why it matters, and how to use it.

Definition (≤25 words). The Long and the Short of It is Binet and Field's 2013 IPA report that established the brand-versus-activation split and the 60:40 budget benchmark.

TL;DR. If modern marketing effectiveness has a founding document, this is it. Drawing on the IPA Effectiveness Databank — hundreds of campaigns whose commercial return was proven with real data — Binet and Field showed that advertising produces two separable effects on two timescales, that emotion drives the long term while rationality drives the short term, and that the most effective budgets balance roughly 60% brand building to 40% activation. The report codified ideas that now run through every serious effectiveness conversation. Reading it is still the fastest way to understand why most marketing budgets are structured wrongly.

What is the report, and where does it sit?

The Long and the Short of It was published in 2013 by the IPA (Institute of Practitioners in Advertising), written by Les Binet and Peter Field. It is the consolidation of work the pair had been doing since Marketing in the Era of Accountability (2007), their first systematic mining of the IPA Effectiveness Awards Databank — an archive unique in marketing, because every entry must prove commercial return with rigour, not just claim it.

The Databank matters because it is the largest body of proven-effectiveness cases in the world. Entrants submit real sales, profit, and market-share data alongside their marketing activity, vetted by judges. Binet and Field did not run a survey or a lab experiment; they pattern-matched across hundreds of real campaigns to find what distinguishes the ones that worked commercially from the ones that did not. That evidentiary weight is why the report's conclusions stuck where so much marketing "research" does not.

The report was updated in 2018 as Effectiveness in Context, which refined the numbers in light of the rising short-termism of the digital era — but the core framework has held.

What are the report's headline findings?

Four conclusions carry almost all the practical weight:

1. Advertising has two effects, on two timescales

The short-term effect is a sales spike — measurable within weeks, driven mostly by activation and promotion, and decaying rapidly. The long-term effect is a baseline lift — building over years, driven by brand building, and compounding rather than decaying. The two are real, separable, and measurable. This is the conceptual bedrock of everything that follows; it is explored in detail in our entry on long-term vs short-term effects.

2. Emotion drives the long term; rationality drives the short term

The Databank shows that campaigns rated as highly emotional are disproportionately associated with profitable, long-term, penetration-driving growth. Hyper-rational, hard-sell work produces short-term sales that decay fast and, over time, can erode pricing by training customers to wait for a deal. This is not a matter of "feeling" versus "logic" in the creative — it is about what kind of memory and motivation the advertising builds, and how long that memory lasts.

3. The 60:40 benchmark

Among the most effective cases, the average budget split was roughly 60% brand building, 40% activation — the origin of the 60:40 rule. It is a centre of gravity, not a target; the 2018 update argues the modern, promotion-saturated environment calls for a more brand-heavy balance. But the number stuck because it is specific enough to argue with and far from where most budgets actually sit.

4. Share of voice predicts share of market

The report reinforced the broader finding that a brand's market share tends to track its share of voice over the long term, and that excess share of voice (SoV minus share of market) predicts share growth. This connects media investment directly to commercial outcomes and is the lever behind most sustained-growth strategies.

Why did it land so hard?

Three reasons. First, the evidence is unusually strong — proven cases, not opinion. Second, the conclusions were counter-intuitive to how budgets were actually being spent in 2013, as digital attribution and performance marketing pulled spend toward the short term. The report gave practitioners and finance directors a data-backed reason to push back. Third, it was practical: it offered a number (60:40), a mechanism (two effects, two clocks), and a clear set of "what to do" implications. That combination — evidence, surprise, and usability — is rare in marketing writing.

Where people get it wrong

  • Quoting 60:40 as a universal optimum. It is an average of the best cases, not a prescription. The report itself stresses context. A brand with no awareness needs more than 60% brand; a mature brand in a price war may need more still. The 2018 update leans further brand-heavy than the 2013 number.
  • Treating "long term" as "unmeasurable." The report does not say brand building is beyond measurement — it says it pays back on a longer clock, using metrics like penetration, pricing power, and share of search.
  • Using the report to defend any campaign labelled "brand." Brand building must still be held to commercial evidence. Sixty percent on brand is not sixty percent on work you cannot justify.
  • Forgetting the emotion finding. The report is not just about budget split; it is about what kind of advertising drives the long term. A brand-building campaign that is rational, rational, rational will not deliver the long-term effect the framework predicts.
  • Dropping the 2018 context. The promotional, digitally-attributed environment has intensified since 2013. Quoting the original numbers without the Effectiveness in Context refinement misleads.

In practice — how to use the report

  1. Read it. It is short, plainly written, and more useful than any secondary summary — including this one.
  2. Classify every pound by objective, not channel. Decide whether each line item is brand building (long-term, emotional, broad-reach) or activation (short-term, rational, targeted), and tag it.
  3. Benchmark your split against 60:40, then adjust for your category, price elasticity, and time horizon. Move toward 70:30 under price pressure or weak mental availability.
  4. Audit the emotion in your brand work. If your "long-term" advertising is functional and rational, it will not deliver the long-term baseline the report describes.
  5. Measure both halves. Pair activation ROAS with penetration, pricing, and share of search so the long-term effect is visible to the board, not just the spike.
  6. Use it as an argument. The report's evidentiary weight is its greatest asset. When a finance director wants to cut brand to protect the quarter, the Databank is your counter.

So what?

The Long and the Short of It is the report most often cited and least often read in modern marketing. Its power is that it turned an abstract tension — "brand or performance?" — into a set of evidence-backed, actionable claims with numbers attached. The specifics have evolved, but the core insight has not changed in a decade: marketing has two jobs on two clocks, and the measurability of the short term will quietly cannibalise the profitability of the long term unless someone holds the line. That someone, in most organisations, has to be the marketer who has actually read the report.
