A world without advertising?

What would the world be like without advertising? Would there be less businesses? Would we make our own stuff more often because of the lack of knowledge in brands? Branding is the foundation of all advertising. Brands are your promise (the company) to the customers that you will provide them with the best product possible. Take Nike for example, it has been accused of putting people in sweatshops to make their products. This is a dangerous environment that is harmful to it's employees. How can Nike stay in business with horrible news like this? It's actually a very easy answer, it's brand. Nike is so well know and it's brand is so strong that it can survive these kinds of things. Bottom line, it provides customer satisfaction.
The growth of advertising is because of four key ideas mass produced goods, mass communication, mass distribution, and mass education. The industrial revolution helped optimize production. With printing, magazines, and newspapers people could now see advertising on a more consistent bases. The evolution of railroads really helped advertising get going. You had away to get your advertisement to any demographic that you wanted. This would also be where research advertising was useful. Finding who used what and advertising it to them. In early advertising, people could not read what the advertisement said. It wasn't because of a fancy font or the words were like a 2 font, but because people just didn't know how to read. And so laws that forced kids to go through k-12 were made and it helped advertising in the end.
So the world really does need advertising. Most of the greatest brands on the planet have relied heavily on advertisements to get sells. For example, coca cola is one of the oldest brands in the world and got it's business going from advertising. Advertising is important because it attaches us with our favorite products.
