Final answer:
Selective advertising is the technique that advertises only the good things about a product while ignoring its negative aspects, focusing on its strengths to increase consumer demand and profits.
Step-by-step explanation:
The technique you're referring to is called selective advertising. This approach emphasizes all of the positive attributes of a product while deliberately omitting any negative aspects. In selective advertising, the focus is squarely on the product's strengths, often embellishing them to make the product seem more appealing to the consumer. This can be seen across various platforms, where synergistic advertising ensures a consistent message about the product's merits. However, it's important to recognize that while this method can increase demand and potentially profits, it also raises ethical questions about consumer manipulation and informed choice.
