In my opinion, both marketing and propaganda are somewhat associated with advertising. Advertising has to do with spreading the word about a specific product or service to the public through several types of media and print. When a company promotes their products to consumers through advertising it directly connects to marketing. I believe marketing is when a business/company puts ideas together to target a group of people who are interested in selling or buying their product. On the other hand, I think propaganda sometimes includes advertising but essentially the idea is to persuade people to believe in the message or mindset they are portraying even if they are falsifying information to do so.
*Do you think propaganda is always negative?
