"Demo" in marketing means showing people how a product or service works. It's like when your teacher shows you how to use a new toy or game before you start playing with it. Companies use demos to help people understand their products better and decide if they want to buy them.
Think of it this way - you're in a store and see a cool toy you want to play with. But before you can buy it, someone from the store shows you how it works. They might give you a small demonstration by showing you how to turn it on and explaining what all the buttons do. This is a demo! The idea is to show you how cool the toy is and how it can make your life more fun.
Demos can happen in different ways. Sometimes a company sends a person to a store to demonstrate their product. Other times, they create videos or ads that show their product in action. They might also set up booths at events or shows where people can come and try out the product for themselves.
In summary, a demo is when a company shows people how their product or service works. It helps people understand the product and decide if they want to buy it. Just like how your teacher shows you how to use a new toy, demos help us learn about new products and make better decisions.
