What is the main idea of this text?

the world today is filled with advertisements. we see them on tv, in the newspaper, on the internet, and in our surroundings. the advertising industry affects the way we look at and judge people around us. catchy taglines and trendy jingles influence our choices on a daily basis. we constantly change our lifestyles depending on the current trends. we feel compelled to buy products that keep popping up on our screens. we struggle to keep up in a race for getting the newest or most popular product.

advertisements have a huge impact on our daily lives.
brand names have no assurance of quality.
advertisements do not impact personal choice.
people are judged by the brands they use.
