Final answer:
In the 1960s, to make their vegetable soup appear more appealing in ads, Campbell's used marbles in a bowl before adding the soup to create the look of plentiful vegetables. This demonstrates the importance of presentation in marketing. It also ties into the business principle that companies often succeed by focusing on a key set of core products.
Step-by-step explanation:
In the 1960s, Campbell's soup experienced a challenge with their magazine advertisements. They needed to make the vegetable soup look more appetizing for potential customers. As the vegetables in the soup would sink to the bottom, this presented a problem for visually appealing imagery. Campbell's solution was inventive; they filled a bowl with marbles and then poured the soup on top, making it look as if the bowl was crammed with vegetables. This gave the soup a much more enticing appearance in photographs.
The approach taken by Campbell's reflects a broader principle in the world of business. Companies tend to be more successful when they concentrate on a limited range of products, which is often referred to as their core competency. This focus allows businesses to specialize and refine their product offerings, leading to greater success than if they were to spread their efforts across a wide range of products.
