Meanwhile, some people besides me agree that advertising is an ideal and persuasive way to urge people to buy productions because it can trigger more potential customers.When individuals watch same advertisement for couple of times, they will vividly remember names of brands and products.If consumers are in need, they will choose the brands they heard before rather than other ones.For instance, in Taiwan, Uber Eats, which is a online delivery platform, not only promote a large amount of advertisement, but also use brainwashing lines to impress customers. And now, Uber Eats gets more downloads than Foodpanda,which is its rivals. Consequently, it is useful to advertise products or services because people will memorize they although individuals do not use immediately.
