Friend Hive account@spectrumecons good you're back, excellent post about the structures of the oligopolies, I liked the approach you gave him and especially name the weaknesses that can have this type of organization as there are many people who often think that these monsters do not have weak points because of how big they are and that they handle a large percentage of the market, But the truth is that they are also weak at a certain point, another point I wanted to highlight is that I agree with you and in my opinion persuasive advertising makes the difference in this type of organization because this type of advertising is easily accessible to any individual and is creating a kind of relationship with the brand. Until next time.... Greetings...
