Showcases on Instagram will engage you with a type of advertising, so that the audience will think about buying a product, instead of explaining the advantages of that product, the device that the audience has at home is called "lacking class", "worst" or "outdated". This form of advertising is aimed at the feeling of satisfaction with the property and pulls out the desire to buy from the heart of the feeling of inadequacy. Two people are sitting in front of the camera. "The best TV? " asks one. And then immediately says the name of a brand. The next question is about the most expensive, the cheapest or the best quality product and other names are mentioned. Fast pace, short answers and decisive tone make these videos attractive for social networks. But behind this brief entertainment, there is a pattern of advertising effectiveness that, instead of emphasizing the benefits of a product, can evoke a feeling of dissatisfaction with existing products. _ Link
