## The situation

On 4 December 2018 Burger King offered American customers a Whopper for one cent. There was one condition. The customer had to download the Burger King app and be standing within 600 feet (about 183 metres) of a McDonald's. Once the order was placed inside the app, it pointed the customer away from the rival's counter and towards the nearest Burger King, where the burger had to be collected within an hour. The offer ended on 12 December.

The company was not short of ways to sell burgers. It was short of people using its app. Burger King had rebuilt the app that autumn to support ordering ahead, and the brand needed customers to download it and put card details into it. Its marketing team had already tried the obvious route, a free Whopper for downloading the app, and by the chief marketing officer's account nobody cared.

The numbers that followed were large for a restaurant promotion. Restaurant Brands International (RBI), the parent company, told analysts on 11 February 2019 that the campaign added 1.5 million app downloads and made Burger King the most downloaded quick service restaurant app in the United States in December. Burger King's own global marketing chiefs said later that the app climbed from number 686 to number one in the App Store in 48 hours. The campaign went on to win the Grand Prix in the Direct category at the Cannes Lions festival in 2019.

This case is about a small decision with a clear mechanism: use the rival's much larger network of restaurants as the trigger for your own offer. It is also a case about evidence. Most of the figures come from Burger King and the agency that made the campaign, and they measure downloads and short bursts of sales rather than lasting customer habits. Both sides of that are worth keeping in view.

## Background

### Burger King and its parent

Burger King was founded in 1954. By the end of 2018, RBI's annual report counted 17,796 Burger King restaurants in more than 100 countries and US territories. Only 50 of them were run by the company itself. The other 17,746 belonged to franchisees. RBI's filing says new franchise agreements in the United States and Canada typically carry a royalty of 4.5 per cent of gross sales, so the parent earns money when franchisees sell more, and it has little cost of its own in each restaurant.

RBI also owns Tim Hortons and Popeyes. The investment firm 3G Restaurant Brands Holdings owned about 41 per cent of its combined voting power at the end of 2018. Burger King made up roughly 70 per cent of RBI's restaurant locations, as the Wall Street Journal reported and Marketing Dive repeated. Global system-wide sales at Burger King were $21.6 billion in 2018, up 8.9 per cent from $20.1 billion in 2017, with comparable sales growth of 2.0 per cent against 3.1 per cent a year earlier. Net restaurant growth was 6.1 per cent. The chain was adding restaurants faster than it was adding sales in each one.

### The smaller rival

In the United States Burger King faces McDonald's, which is much larger. The effectiveness case later entered for the campaign says Burger King had about half as many locations as McDonald's, which made it harder for customers to find one nearby. Contagious reported that the campaign geofenced more than 14,000 McDonald's restaurants across the country. That figure is the best available guide to the size of the rival's footprint, since the agency drew the map around every one of them.

### An app nobody was using

Burger King had a mobile app before December 2018, and interest in it was low, according to the effectiveness case. The company needed the app to work because mobile ordering, loyalty and delivery were where it expected the market to go. RBI's chief executive José Cil said in the fourth-quarter results that the company had made progress on delivery, kiosks and mobile app development. Business Insider, writing in February 2019, reported that executives put total downloads at over 6 million, up from 2 million in October, with about 4 million downloads between October and the end of December.

That October figure matters. It shows the app was starting from a small base, which is why a promotion that produced 1.5 million downloads could be reported as a major result.

## The industry

American quick service restaurants compete on price, convenience, taste and, increasingly, on who owns the direct relationship with the customer. RBI's annual report describes the competition in broad terms: independent local operators, regional, national and international chains, fast casual restaurants, convenience stores and delivery aggregators. It also notes the expansion of mobile ordering, delivery, loyalty schemes and digital payment across its brands.

Marketing Dive described the pressure from younger customers in the same period. Millennials and Gen Z, it said, were moving from traditional fast food to fast casual chains they saw as healthier, and mobile ordering, payment and delivery were ways for established brands to reach them. Pascoe, Burger King's head of global marketing, said at Cannes in June 2019 that almost every fast food restaurant now offered mobile order and pay, so the task was to stand out and win preference. An app is easy to copy, and customers are not obliged to use one chain's version.

The economics gave Burger King a reason to care. Contagious cited Deloitte Digital research that 40 per cent of Americans prefer to order food online and that online quick service customers spend 26 per cent more than customers who order in store. For a franchised business, digital orders also carry a technology fee: the 2023 annual report says franchisees pay a fee on all digital sales through RBI's own technology. A customer who orders in the app therefore gives the parent company data and a fee as well as a royalty.

The rival's size cut both ways. McDonald's had more restaurants, so a Burger King was less likely to be nearby. But a customer standing outside a McDonald's was, by definition, a customer who wanted a burger. That was the opening the campaign used.

## The decision

Burger King had to choose how to get a smartphone app into people's hands and get them to use it. The sources describe one option the team tried and abandoned. The others below are the obvious alternatives, framed as such, since the sources do not report that the team formally compared them.

### Give the burger away for a download

The team tried this first. Marcelo Pascoe, speaking at Cannes Lions in June 2019, said Burger King had earlier trialled a free Whopper in return for an app download and nobody took it up. Fernando Machado, the global chief marketing officer, said of the same idea: "Didn't work. No one cared about it." Digital Strategy Consulting reported the remark. The point is worth holding on to. A free product did not produce interest, but a one-cent product with a game attached did. Pascoe said the success came from the fun of the campaign rather than from the price.

### Run ordinary app discounts

The second route was a standard coupon inside the app, available to anyone. Contagious reported that the Whopper Detour redemptions were four times those of regular Whopper discount offers. That comparison suggests the company had run such offers before. A general coupon would also give away margin to people who were already coming, and it would not take anyone from McDonald's.

### Advertise the new features

The third route was conventional advertising of the app's order-ahead feature. The sources do not describe this as a serious alternative for the December push. It would have competed for attention with every other restaurant's mobile promotion, and it would have asked customers to download an app because it was better, which is a hard claim to prove in an advert.

### Use the rival's restaurants as the trigger

The option Burger King chose was to make the rival's location the key to the offer. The agency, FCB New York, built a mechanism around the one place where a customer was already thinking about a burger and had already chosen a competitor. The WARC write-up describes the insight as turning McDonald's larger footprint into an advantage for Burger King. The risk was practical as well as reputational. The campaign relied on customers standing close to a McDonald's and then driving or walking away from it.

## What they did

### Building the mechanism

The offer was narrow by design. Only the Whopper cost a cent, and fries and drinks were at full price. Contagious noted that anyone coming in for the burger was therefore likely to buy something else. Each customer could use the offer only once, according to Digital Strategy Consulting. The app used location data to see when a customer was inside the 600-foot ring around any of the 14,000 McDonald's restaurants. B&T gives no further technical detail, and no source describes the cost of the build.

The one cent also had a purpose. Contagious observed that charging even a cent meant the customer had to put a payment card into the app, which could make a later full-price order easier. That is the publication's reading, not a statement from the company.

### The launch film

FCB New York made the announcement video. It shows confused customers asking for Whoppers at McDonald's drive-throughs and McDonald's staff directing them to Burger King. A second video explained how to redeem. Its small print advised, according to Contagious, that there was no need to use the McDonald's drive-through window. The tone was a prank played on a rival. None of the sources opened for this case reports a McDonald's response.

### Nine days in December

The offer opened on 4 December and ended on 12 December 2018. On 6 December Machado told the Most Contagious conference that the app had reached number one in the App Store's Food and Drink category within a few hours of launch. He gave a figure of over 2 million downloads in 48 hours and about 150,000 one-cent Whoppers redeemed. He said downloads were more than 13 times redemptions and that Burger King had one of its highest footfall levels in restaurant history.

The redemption figure puts the price in perspective. At one cent each, 150,000 Whoppers brought in about $1,500 (this is simple arithmetic on the reported number). The value of the campaign was never in those sales.

### Reporting it to investors

The results reached investors on 11 February 2019, when RBI reported its fourth-quarter figures. Cil told analysts that the campaign added 1.5 million downloads and made the Burger King app the most downloaded quick service restaurant app in the United States in December. Marketing Dive reported that the app was also the most downloaded app in Apple's App Store for several days in a row. Business Insider quoted Cil describing it as "a fun promotion that drove a lot of downloads and also allowed us to focus on our flame-grilling heritage". The company framed it as a success, in measured words.

## What happened

### The numbers

The reported results come from three kinds of source: statements by RBI executives on earnings calls, remarks by Burger King marketers at industry events, and award entries. They do not agree exactly, and they measure different periods.

The two download counts differ. Contagious reports more than 2 million in 48 hours from a speaker on 6 December, while RBI told analysts 1.5 million after the campaign. The sources do not explain the gap. The difference may come from a different counting period or an early estimate that was later revised, but that is a guess. Both figures are given here and neither is preferred.

### Recognition

The Cannes Lions jury gave the campaign the Grand Prix in the Direct category in June 2019. Digital Strategy Consulting reported two golds in the Direct Lions and four golds in the Media Lions. The Direct jury president, Nicky Bullard, said: "It used data and targeting to make you feel something. It's just pure genius." Machado called it "the most indirect idea to win the Direct Grand Prix in Cannes ever." WARC also lists a Grand Prix at the Effie Awards North America.

### What it did for the business

The reported effect on sales is modest next to the download count. Burger King's American comparable sales grew 0.8 per cent in the period RBI reported, and the campaign accounts for only a part of that. The effectiveness case puts incremental revenue at $15 million, which is small against a business with $21.6 billion of global system-wide sales. The case for the campaign therefore rests on what the downloads were worth later, and that is where the public evidence is thinnest.

## Other views

### The judges and the marketers

The jurors who gave the awards were enthusiastic, and their comments are about the idea. Robin Fitzgerald, a juror and chief creative officer at BBDO Atlanta, said: "It was a coupon. You can't get more direct than that." Machado's own gloss was that the campaign showed "the power to bend logic". These comments tell us the work was admired by peers. They do not tell us whether the customers returned.

### The investor's reading

The chief executive's description was understated. A fun promotion that drove downloads is a smaller claim than a change of strategy. Business Insider noted that RBI released these results with the management changes it announced in the same period. A promotion that gets a one-line mention is being treated as a useful tactic, not a rescue of the brand.

### The limits of the evidence

Three limits apply. First, almost all the numbers are supplied by the company or the agency, and the ROI and revenue figures come from an effectiveness case entered for an award, which is written to persuade. Second, no source opened for this case gives a measure of how many of the new users ordered again at full price, or how many deleted the app. Third, no source gives the campaign's budget, so the 37 to 1 return cannot be checked. B&T reported that mobile sales had doubled since the campaign, which is the best available sign of a lasting effect, but it is a Burger King statement without a base figure.

There is a further point about McDonald's. None of the articles opened for this case reports a reply from the company. The absence may mean there was none. It may also mean reporters did not ask, or that McDonald's chose to say nothing.

## Reading it through a framework

### Porter's five forces

Michael Porter's model looks at rivalry, the power of buyers, the power of suppliers, and the threats from new entrants and substitutes. Rivalry in burgers is intense and McDonald's holds the larger network. Buyers have strong power here, because switching from one burger chain to another costs a customer nothing, and Pascoe's point that almost every chain offers mobile ordering means the app does not by itself shut the door on a rival. Franchising shapes the supply side: franchisees pay royalties and, on digital sales, a technology fee to RBI, so RBI's position rests on the brand and its technology.

The Detour attacked the buyer force directly. It lowered the customer's switching cost to near zero for one burger, then used the app to collect the card details that make the next order easier. In five forces terms, the campaign tried to build a small switching cost of its own, because a customer who has stored a card and a favourite order is a little less likely to go elsewhere. The evidence for that effect is thin, but it explains why the company paid for downloads rather than sales.

### AIDA

AIDA stands for attention, interest, desire and action. The campaign handled each stage with a single object. Attention came from the premise: a burger chain paying customers to walk past its main rival. B&T reports 3.5 billion impressions on news networks. Interest came from the prank film and the puzzle of how a one-cent Whopper could work. Desire came from the price, and from the pleasure of taking part in a joke at McDonald's expense. Action was the download, the order and the pickup.

The action step was demanding. Customers had to install an app, stand near a competitor and then go to a Burger King, so those who completed it had made a real effort. Machado said downloads were more than 13 times redemptions, which fits this: most people took the cheap first step and fewer took the whole route.

## Since then

The sources opened for this case say little about the campaign after 2019. B&T reported in June 2019 that mobile sales had doubled since the promotion, and Digital Strategy Consulting reported the Cannes awards the same month. WARC published the Effie Grand Prix case in December 2020.

The wider business has moved on. RBI's 2023 annual report counts 19,384 Burger King restaurants, of which 7,144 are in the United States and Canada. Global system-wide sales for the brand were $27.0 billion in 2023. The same filing says RBI provides digital loyalty programmes across its brands and that use of its mobile apps continues to increase. It also says RBI has agreed to buy Carrols, its largest American Burger King franchisee, in a deal expected to complete in the second quarter of 2024, adding about 1,020 Burger King restaurants. That is a change from the almost entirely franchised model described in the 2018 report.

The filings do not credit the Whopper Detour with any of these changes, and nothing in the sources links the campaign to the later strategy.

## What to take from it

- A rival's strength can be turned into a prompt for your own offer. The campaign used the 14,000 McDonald's restaurants as triggers because they were where hungry customers already were.

- A free offer is not always more attractive than a cheap one with a story. Burger King's earlier free-Whopper-for-download idea failed, while a one-cent burger with a game attached worked.

- Measure what the campaign is for. Downloads rose sharply, but comparable sales rose only 0.8 per cent, so the real test is what later orders the new users placed.

- Award-entry numbers come from the entrant. The $15 million and the 37 to 1 return are claims made to persuade a jury, and the two download counts show how figures drift between sources.

- A narrow discount protects margin. Only the burger cost a cent, so people who came in were likely to buy other items at normal prices.

## Questions to think about

- If downloads were the goal, which measure would show that the 1.5 million new users were worth having six months later?

- McDonald's did not appear to respond in public. What would a response have cost it, and what would silence cost it?

- How would the campaign have to change if the rival's restaurants were far fewer, or if customers could redeem the offer without visiting a competitor?

- Does a promotion built on a joke at a rival's expense build loyalty to your own brand, or only attention for a few days?
