Is it possible in any way to influence the formation or change in demand?

There are many mechanisms for influencing the demand for certain goods and services. One of the most effective is advertising. With the help of advertising, the manufacturer recommends his product or service, imposing it on the consumer. He convinces him that he needs to buy what is advertised.
Another strong increase in demand is fashion and trend. If a manufacturer is even half a step ahead of fashion, then he is a successful businessman. In my opinion, the best mechanism for increasing demand in the long term is to improve the quality of products. Quality products will always be in great demand.
