Introduction to Marketing

Most students think marketing means adverts. It does not. Marketing is the whole job of working out what people actually want, then making sure your business is the one that gives it to them — and still makes money doing it. Everything else in this unit hangs off that one sentence.

What marketing actually means

A market does not have to be a physical place. If a buyer and a seller can find each other and agree a price, that is a market. An online marketplace is a market. A car boot sale is a market. The market for insurance is spread across thousands of phone calls and web pages.

The definition examiners want is that marketing helps a business identify, anticipate and satisfy customer needs and wants profitably. Take those four words one at a time, because each one is doing a job:

Needs and wants are not the same thing

A need is essential to live: food, clean water, shelter, warmth. A want is a desire for a particular way of meeting that need. You need food; you want a specific brand of cereal. You need shoes for winter; you want a particular pair of trainers.

This matters because wants are where the profit lives. Needs are usually met by cheap, similar products that compete mainly on price. Wants can be shaped by branding, design and advertising, which is why firms are willing to spend so much on them.

If a question asks you to explain why a firm spends heavily on marketing a fairly ordinary product, the answer is nearly always this: it is trying to turn a need into a want, so it can charge more than a plain substitute.

Product orientation versus market orientation

Every business has to answer one question first: do we start with the product, or with the customer? That single choice changes how the whole firm behaves.

Two ways to decide what to sell The starting point is different, and so is the risk PRODUCT ORIENTATION Business designs the product Then it looks for a market Hopes customers want it Risk: a great product nobody asked for MARKET ORIENTATION Business researches buyers Then it designs the product Buyers already exist Risk: research costs time and money Most large firms are market oriented, but both approaches still exist Inventors often start product oriented and only research the market later
The two routes end in the same place — a product on sale — but one of them checks that somebody wants it before the money is spent.
Point of comparisonProduct orientationMarket orientation
Starting pointThe idea, the invention, the recipeThe customer and what they say they need
Belief behind itA good enough product will sell itselfNothing sells unless somebody wants it
Main strengthCheap to start, can create brand new marketsLower risk of a flop, demand is checked first
Main weaknessThe firm can drift away from what buyers wantResearch costs money and can be out of date
Typical userInventors, engineers, small craft producersSupermarkets, phone makers, service firms
Do not treat product orientation as simply wrong. Genuinely new products cannot be researched properly, because customers cannot describe something they have never seen. The honest answer in an evaluation question is that most firms use a mix: an idea from the workshop, then tested against the market before launch.

Market share

Market share answers one question: how big is our slice? It compares one firm’s sales with the sales of the whole market. It can be measured by sales value (money) or sales volume (units sold), and the two can give different answers — a firm selling cheap items can have a big share of volume and a small share of value.

Market share market share (%) = (sales of one business ÷ total sales of the market) × 100
WORKED EXAMPLE

A bakery chain had sales of $4.2m last year. The whole bakery market in that country was worth $56m. Calculate its market share to two decimal places. [3 marks]

Step 1: pick out the two figures Firm’s sales = $4.2m    Total market = $56m Step 2: put them into the formula (4.2 ÷ 56) × 100 Step 3: work it out 0.075 × 100 = 7.5 Market share = 7.50% Both figures are in millions, so no unit conversion is needed. Write the formula down even if the arithmetic goes wrong — it usually earns a mark on its own.
Unit trap. If one number is in millions and the other is in billions, convert first. $4.2m out of $5.6bn is not 75% — it is 0.075%. Getting this wrong is the single most common lost mark in market share questions.

Market growth

Market growth looks at the whole market, not one firm. It tells you whether the cake is getting bigger or smaller. Positive growth means the market is expanding; negative growth means it is shrinking.

Market growth market growth (%) = ((new market size − old market size) ÷ old market size) × 100
WORKED EXAMPLE

A national market for plant-based ready meals was worth $18.5m in 2024 and $21.4m in 2025. Calculate the rate of market growth to two decimal places. [2 marks]

Step 1: find the change in size 21.4 − 18.5 = 2.9 Step 2: divide by the old size 2.9 ÷ 18.5 = 0.156756… Step 3: multiply by 100 0.156756… × 100 = 15.6756… Market growth = 15.68% Always divide by the starting year, never the new one. Dividing by 21.4 gives 13.55% and loses the mark.
WORKED EXAMPLE

A market had sales of $640,000 in 2025 and is expected to grow by 12% in 2026. Calculate the predicted market size for 2026. [2 marks]

Step 1: find 12% of the 2025 figure 0.12 × 640,000 = 76,800 Step 2: add it on 640,000 + 76,800 = 716,800 Predicted market size = $716,800 This is just a percentage increase. Doing 640,000 × 1.12 in one step is fine and gives the same answer.
Share and growth are easy to muddle. Share is about you inside the market. Growth is about the market itself. A firm can lose market share in a fast-growing market and still sell far more than last year — a lovely evaluation point.

Niche markets and mass markets

A mass market aims at a broad group of buyers with a fairly standard product. A niche market aims at a small, specialised group inside that wider market. The niche is not a separate world — it sits inside the mass market, serving a slice of buyers whose needs the big firms have not bothered with.

A niche sits inside the mass market Same product area, very different scale and strategy MASS MARKET Broad group of buyers Low price, large volume NICHE Small group Higher price Mass: supermarket sliced bread Sold everywhere, tiny profit per loaf Niche: gluten-free sourdough Fewer shops, much bigger margin Niche firms accept fewer sales in return for a higher price A niche can grow into a mass market if enough buyers appear
Notice the niche is drawn inside the bigger box. Both are selling bread — the difference is who they are selling it to and at what price.
FeatureNiche marketMass market
ProductSpecialised, often uniqueStandard, similar to rivals
Scale of productionSmall, so no economies of scaleLarge, so unit costs fall
Average costsHigh per unitLow per unit
Price and volumeHigh price, low sales volumeLow price, high sales volume
Profit marginHigher margin on each saleThin margin, profit comes from volume
Main riskThe small group of buyers disappearsHeavy competition drives prices down

The trade-off is the point of this table. A niche firm earns more on every single sale but has far fewer sales to earn it on. A mass-market firm earns almost nothing per unit but sells enormous quantities. Neither is automatically better — it depends on the firm’s costs, its capacity and how loyal its customers are.
