From Nestlé Secret to Mars Celebrations: Innovation, commercial reality and the changing face of the industry have been powerful factors for the confectionery sector, as experienced British confectioner Geoffrey O’Sullivan reflects.

There was a time when confectionery innovation seemed to mean doing something genuinely different.

A new texture. An unexpected centre. A chocolate bar that looked different from anything else on the shelf. Something that would make people stop, look twice and want to try it.

But creating something different is only the beginning. Can it be manufactured consistently? Can it be sold at a price consumers will accept? Will they buy it again? And, perhaps most importantly, can a product that captures the imagination become a sustainable commercial success?

These are not new questions. Yet, looking back at the confectionery industry over several decades, I wonder whether the balance between creative ambition and commercial certainty has changed.

Having worked at Cadbury, Kraft and British Sugar PLC, I have an interest in how businesses develop products, build brands and make commercial decisions. Looking back, I wonder whether the industry’s appetite for a particular kind of innovation has changed.

To explore that question, it is worth revisiting two very different confectionery propositions: Nestlé Secret and Mars Celebrations. Their stories illustrate two approaches to innovation. One challenged conventional ideas about what a chocolate bar could be. The other found a new way to bring familiar products together. Both offer valuable lessons about creativity, consumer expectations and commercial reality.

When innovation meant doing something different
There was a time when the ambition to create something genuinely new seemed central to the identity of many major food businesses.
Companies expanded their portfolios, entered new categories and invested in product development. Innovation could mean a new recipe, a different texture, an unusual combination of ingredients or a product that required new manufacturing techniques. The objective was not simply to offer consumers another choice. It was to give them a reason to try something they had never experienced before.

The history of Cadbury and Schweppes illustrates the broader corporate ambition to diversify. Their merger in 1969 brought together businesses with different product traditions, and subsequent acquisitions expanded their portfolios. The acquisition of Trebor and Bassett Foods in 1989, for example, strengthened Cadbury Schweppes’ position in confectionery.

Diversification offered opportunities to broaden distribution, build brands and enter new markets. It also created a larger commercial framework within which products could be developed and supported.

But a broad portfolio does not automatically produce more innovation. As businesses grow, they must decide where to invest, which categories to prioritise and how to balance the potential of new ideas against the performance of established products. Over time, those decisions can change the character of a business.

Nestlé Secret: the ambition to create something extraordinary
Nestlé Secret remains an interesting reference point in confectionery history.
Its delicate, nest-like chocolate exterior and creamy mousse centre made it visually distinctive. It was not simply another solid chocolate bar with a different flavour. Its construction, appearance and texture were central to the experience it promised.

Secret represented a particular ambition in new product development: create something sufficiently unusual that consumers would be intrigued by it, want to try it and remember the experience.

That ambition deserves recognition. Confectionery is an intensely sensory category, and a product that offers something unexpected can create excitement in a crowded market.

But the more distinctive a product becomes, the more questions a business may have to answer. Can it be manufactured consistently at commercial scale? Can the product survive distribution and handling without compromising its appearance or texture? Does the experience justify the price? And will consumers return after the initial curiosity has passed?

These are the realities that separate a compelling product concept from a sustainable commercial proposition.

For me, Secret has become a symbol of the risks associated with one particular approach to innovation: the belief that a sufficiently distinctive product will, by virtue of its originality, find a lasting market.

I have sometimes described it as “the nail in the coffin for that style of innovation”. That is my personal interpretation, not a proven explanation for Secret’s commercial fate or the closure of a particular factory.
The point is not that Secret was a bad idea. Its ambition is precisely what makes it interesting. Rather, it reminds us that technical ingenuity and originality are only part of the equation. Consumer demand, manufacturing economics, distribution and repeat purchase all matter.

A product can be memorable without becoming a permanent fixture. And yet, if businesses become too cautious because distinctive products carry greater uncertainty, what happens to the ambition that produced products like Secret in the first place?

Mars Celebrations: a different kind of innovation
A contrasting example is Mars Celebrations, launched in 1997.
Rather than introducing an entirely new confectionery experience, Celebrations brought miniature versions of familiar brands together in a single assortment. Consumers could recognise products they already enjoyed, but experience them in a different format and sharing occasion.

The innovation lay in the combination, convenience, variety and presentation.
This was commercially intelligent. Each established brand brought recognition and familiarity, reducing the need to persuade consumers to embrace an unfamiliar flavour or texture. The assortment created a new proposition from products that already had their own identities.

Celebrations also illustrates an important point: innovation does not have to involve inventing a new recipe. A different size, format, package, assortment or consumption occasion can create meaningful value. Repositioning an established product for gifting, sharing or a different moment of consumption can open up opportunities that the original format did not address.
There is nothing inherently inferior about this approach. Indeed, it can be highly effective. But it raises an important distinction.

“Are we creating new products, or are we creating new ways to sell products we already have?”

Both can be innovation. Both can deliver commercial success. The concern arises only if the second approach increasingly displaces the first because it appears safer, more predictable or easier to justify financially.

The industry needs successful extensions of familiar brands. It also needs the willingness to develop products that offer genuinely different experiences. The challenge is to preserve both ambitions.

When the factory closes, what else changes?
The story of confectionery innovation cannot be separated entirely from the changing structure of the industry.

Over the decades, acquisitions, restructuring and manufacturing consolidation have reshaped where products are made and how businesses organise their operations.

The closure of Terry’s historic York factory in 2005, following Kraft’s acquisition of Terry’s in 1993, brought an end to a long-established manufacturing chapter in the city. Production moved to other European facilities, with significant consequences for the local workforce.

Mars also restructured its Slough operations in 2005. Its Liverpool Road factory closed, while chocolate manufacturing continued at the Dundee Road site. Some confectionery production moved elsewhere in Europe.

These changes reflect commercial decisions about capacity, costs, investment and the organisation of production. They should not automatically be interpreted as evidence that innovation declined. Consolidation can create larger facilities, improve consistency and provide access to technical capabilities that smaller operations might struggle to support.

However, factories are more than buildings and machinery.
They contain accumulated knowledge: how ingredients behave, how a product responds to changes in temperature, how to maintain texture at scale and how to solve the practical problems that do not always appear during laboratory development.

When manufacturing moves, that knowledge must be transferred, rebuilt or adapted. Some changes may improve capability; others may make certain products more difficult or expensive to produce.

A product that fits an established high-volume process may be straightforward to support. One that requires specialised equipment, additional handling or a different production rhythm may face a more complicated investment decision.

This is where manufacturing strategy and product innovation intersect. If businesses increasingly concentrate production in fewer facilities, does that encourage the development of products suited to standardised processes? Does it make experimentation more expensive? Or can centralised technical expertise help businesses take on more ambitious projects?

The answer will vary between companies and products. The important point is that the manufacturing environment influences which ideas are practical, which receive investment and which eventually reach consumers.
The influence of ownership and commercial priorities
Ownership changes can also reshape the environment in which innovation takes place.

Cadbury’s acquisition by Kraft in 2010 was a major event in the history of the British confectionery industry. Cadbury’s international snacks business subsequently became part of Mondelez International.

Such changes can bring investment, wider distribution, technical resources and access to new markets. They can also introduce different expectations around profitability, capital allocation and the performance required from individual brands.

There is no simple rule that larger businesses innovate less, or that independent businesses innovate more. A well-resourced international company may be better equipped to develop a complex product than a smaller competitor. Equally, a business with a strong focus on established brands may be reluctant to invest in an uncertain concept that does not fit its existing portfolio.

The decisive factor is how the business chooses to balance immediate commercial priorities against longer-term opportunities.

New product development inevitably involves uncertainty. Consumer research, prototypes and trials can reduce that uncertainty, but they cannot eliminate it. A product may generate interest without producing repeat purchases. A promising concept may prove difficult to manufacture economically. Another may require a longer period of consumer education before its value becomes apparent.

Established products enjoy an advantage: businesses understand their manufacturing requirements, consumers recognise the brands and sales patterns provide a basis for forecasting.

It is therefore understandable that companies frequently favour extensions of successful ranges. But if every development must offer a relatively predictable return within a short period, genuinely different concepts may struggle to secure the time, investment and commercial support they need.

This is not an argument against financial discipline. It is an argument for recognising that different types of innovation require different approaches to evaluation.

The modern confectionery aisle: more choice, less difference?
Which brings me back to the impression that started this article.
Looking at confectionery today, I sometimes feel that there is more choice than ever, but less obvious distinction between many of the products on offer.
The industry has become highly accomplished at extending successful brands, introducing new flavours and refreshing familiar propositions. These activities can be commercially effective, and consumers clearly enjoy many of the resulting products.

But a new flavour is not necessarily a new experience. A different wrapper does not automatically make a product innovative. And a limited edition that attracts attention for a few weeks may not create lasting value.

The question is not whether every product must be revolutionary. That would be unrealistic, and probably undesirable. Consumers value familiarity as much as discovery, and many successful products earn their place precisely because they deliver a consistent experience.

The question is whether we have become too comfortable with variations on established ideas.

Consider the difference between a product that changes the way consumers experience confectionery and one that simply adds another flavour to an existing range. Both have a place, but they are not necessarily equal in terms of originality, technical ambition or the opportunities they create.
Perhaps the apparent sameness I see is partly a consequence of the maturity of the market. Many flavour combinations, textures and formats have already been explored. Consumers have established preferences, and brands have built their identities around familiar products.

But maturity should not mean that the possibilities have been exhausted.
New ingredients, processing technologies, textures and combinations can still create distinctive experiences. So can a fresh understanding of consumer needs, or a willingness to challenge assumptions about what a confectionery product should look, taste or feel like.

The opportunity is not simply to launch more products. It is to develop products that offer consumers a compelling reason to choose them.
Has the industry become more cautious about originality?
Nestlé Secret and Mars Celebrations represent two different routes to innovation.

Secret pursued a distinctive product experience. Celebrations created a new proposition from familiar brands. Neither approach is inherently right or wrong, and the commercial outcomes of individual products cannot, by themselves, establish a general rule about the industry.

Yet the contrast provides a useful framework for thinking about the future.
The industry needs the creativity to imagine something consumers have not experienced before. It also needs the commercial judgement to recognise when a new format, combination or occasion can deliver greater value than an entirely new product.

The danger lies in allowing the pursuit of predictable returns to narrow the range of ideas that businesses are prepared to consider.
Confectionery has always been about pleasure, anticipation, texture, flavour and discovery. Its appeal lies partly in the ability to surprise us, to create a moment of enjoyment and to offer an experience that feels worth repeating.
If innovation becomes little more than a sequence of minor variations, the industry risks missing opportunities to create the next genuinely distinctive product.

Equally, originality without consumer value is not enough. A product must offer something people want, be capable of consistent manufacture and justify its place in the market. The task is to combine imagination with commercial reality, rather than allowing one to eliminate the other.

Making room for the next big idea
Perhaps the next important confectionery innovation will not resemble Nestlé Secret at all. It may be a new texture, a different sensory experience, a novel ingredient combination or a format that changes when and how people enjoy confectionery.

It may also come from a seemingly modest development that gives consumers a compelling new reason to buy an established product.
What matters is not whether the idea is entirely new or builds on something familiar. What matters is whether it creates meaningful value.

But I would like to see the industry continue to make room for ideas that challenge conventional thinking — including concepts that are technically demanding, commercially uncertain or difficult to fit into existing manufacturing systems.

That requires a willingness to test, learn and sometimes accept failure. Not every ambitious idea will succeed, and not every successful product needs to reinvent the category. The objective is to maintain a healthy balance between the two.

Looking back at Secret, Celebrations and the manufacturing changes that have reshaped the industry, I am left with a question for confectionery developers, manufacturers and brand owners.

“Are we creating the next generation of distinctive confectionery products, or are we becoming better at selling variations of what we already know?”
I would be interested to hear how others in the industry see it.
Innovation isn’t about being different for the sake of it. It’s about making a difference that people value.
