Cadbury's "Not Just a Cadbury Ad" decoded for small brands

Most Diwali ads ask you to feel something. This one asked you to walk into a specific shop in your own neighbourhood, and it named the shop.

Not Just a Cadbury Ad is a hyperlocal ad campaign in which Cadbury Celebrations gave its advertising space to small Indian retailers. The first version ran in 2020. The 2021 version, which won at Cannes Lions, used AI to make Shah Rukh Khan name local stores. With Diwali close, it is the best case study a small brand can copy right now.

What is the Not Just a Cadbury Ad campaign?

It is a Diwali campaign where a Cadbury ad promotes the small shop near the viewer instead of only Cadbury.

Ogilvy and Wavemaker's WPP case study says the campaign began in 2020 to help small businesses hit by the pandemic. In 2021 the team used machine learning so Shah Rukh Khan, Cadbury's brand ambassador, could ask passers-by to shop locally for Diwali. The line of the campaign was "Iss Diwali Aap #KiseKhushKarenge?", reported by BW Marketing World.

How did the campaign work, step by step?

It worked in four moves: map the shops, personalise the film, run it by location, and let shopkeepers make their own.

According to Wavemaker's case page:

1. Machine learning recreated Shah Rukh Khan's face and voice (tech partners Rephrase.ai and DeltaX) so he could name a nearby store.
2. The ads ran on Facebook and YouTube at the same time, aimed at 500+ pincodes and 2,500+ business owners in grocery, clothing, footwear, eyewear and electronics.
3. A microsite, NotJustACadburyAd.com, let shopkeepers or customers make their own version, download it and share it on WhatsApp and social media.
4. Outdoor ads in some areas showed a ticker of local store names, per BW Marketing World.

The 2020 version was simpler. It tagged stores within 2 km of the viewer across 300+ pincodes, again per Wavemaker.

Who was the Not Just a Cadbury Ad really made for?

It was made for the shopkeeper, and the viewer was the delivery route.

Read the business facts. Wavemaker reports that small traders contributed over 80% of Celebrations sales, that offline trade was 95% of the business, and that Diwali was over 45% of annual sales. WARC's summary puts the share of gifting stock sitting in small local shops at over 70%. Different sources give different numbers, but all say the same thing: Cadbury's gifting box lives or dies on a kirana shelf.

Now see the problem. Wavemaker says grocers focused on essentials and gave chocolate less shelf space. An ad that makes a shopkeeper proud, with the biggest star in India saying his shop's name, buys goodwill that a trade scheme cannot. The viewer gets a reason to visit. The shopkeeper gets a reason to stock more.

That is the idea most write-ups skip while they describe the AI: the brand spent its media on the people who decide what is on the shelf, and paid them in attention.

Why did the campaign spread?

It spread because a person's own shop name is the strongest hook an ad can have.

Three choices carried it:

• The name. A shopkeeper hears his own shop in a star's voice. People forward that.
• The delivery. Simplify360 describes a short form where you pick your category and details and get the video link on WhatsApp, the app every shopkeeper already uses.
• The permission to share. The ads could be downloaded and posted, so every shop became a small distributor of the campaign.

The creative was a single idea repeated thousands of times. That is cheap to make once the template works.

What results were reported, and what do they prove?

The reported results are big, but they come from the case studies themselves, so treat them as the brand's own account.

Notice the store count: 2,000 in one source and 2,500+ in another. LBB's page also says it gives no budget, no baseline for the 22% and 18% lifts, and no proof that the sales growth came from the ads. The case study leaves those out, so do not build your plan on the numbers. Build it on the mechanism.

How can a small brand copy this on a small budget?

Copy the mechanism, which is naming the local retailer in your ad, with tools you can afford this week.

1. Start with 10 retailers. Choose the shops or marketplace sellers that already stock you. A D2C brand on Nykaa, Amazon.in or Flipkart can name its top city stockists the same way.
2. Make one template. One 15 second reel with a clean gap where the shop name and city appear as text. In CapCut or Premiere Pro, swapping the name takes minutes. You do not need AI voice for this.
3. Run it by location. On Instagram or Google ads, set a radius around each shop. Start with a small daily test, for example ₹300 to ₹500 a day for one cluster, and compare the cost per visit with your normal ad.
4. Send the file to the shopkeeper. Deliver it on WhatsApp with one line: "Here is your Diwali ad, post it if you like." This is where the goodwill is built.
5. Ask for one action. A visit, a store-locator tap, or a "show this reel for a gift" offer. Count it.

If you have never defined what a shopkeeper should remember about you, start with what brand positioning is, because a name in an ad only works when the brand behind it is clear. If this reads like the plan you need but you cannot see who would film it, send me the product and the list of stores at divyanshrawat.info@gmail.com, or connect on LinkedIn. Planning the one template and filming the product shot people remember is the part of the job I enjoy most.

From a brand strategist view, the lesson is the same as the Cadbury one: decide who your first customer is. Often it is the person who puts you on the shelf.

What should a brand avoid when it tries this?

Avoid anything that makes the shop look like a prop or promises more than you can deliver.

• Fake stockists. If a shop does not stock you, naming it wastes the goodwill. LBB notes the campaign gives no detail on how misleading listings were handled.
• Using a real person's face or voice without permission. The sources I read do not say how Shah Rukh Khan's likeness was licensed. Use your own team or a willing creator.
• Too many versions. Ten well-made ads beat a hundred sloppy ones. The look of your ads matters, as why Indian D2C brands look the same on Instagram explains.
• No follow-up. If the shop does not hear from you after the ad, the goodwill fades.

Questions people ask

What is the Not Just a Cadbury Ad campaign?

It is a Cadbury Celebrations Diwali campaign by Ogilvy and Wavemaker that features small local shops in Cadbury ads. It started in 2020 and was expanded in 2021 with Shah Rukh Khan naming nearby stores using AI.

Who made the Not Just a Cadbury Ad campaign?

Ogilvy handled the creative and Wavemaker handled media, for Cadbury Celebrations, which is owned by Mondelez International. Rephrase.ai and DeltaX are named as technology partners on Wavemaker's case page.

How did Cadbury use AI in the Shah Rukh Khan ad?

Machine learning recreated Shah Rukh Khan's face and voice so he could say the name of a nearby store. Ads were then targeted by pincode on Facebook and YouTube, and a microsite let shopkeepers create their own versions.

Did the Not Just a Cadbury Ad campaign work?

Case studies report 130,000 ads, 94 million views and a 9.4% household penetration, a three-year high. The sources I read give no budget or baseline, so the sales impact is the brand's own claim.

Can a small brand run a campaign like Not Just a Cadbury Ad?

Yes, at a smaller scale. Name your top 10 stockists in a reel template, run it near each shop with a small location-targeted budget, and send the file to the shopkeeper on WhatsApp. You do not need AI to start.

Why did Cadbury promote small shops in its own ad?

Reports say small traders held most of Celebrations' sales and gifting stock, and the pandemic had cut their shelf space for chocolate. Promoting those shops kept the brand on the shelf at Diwali.
