One leads to the other easily. For example taking advertising money for television commercials or magazine adds leads to "Native Ads". Native ads are sort of like product placement except that it's pretending to be a news story or whatever.
Like when people on CNBC or CNN start talking about Taco Bell menu items or new type of drug that might fight cholesterol. That's paid-for propaganda that is pretending to be television news.
Pretty soon you have a entire industry based on not telling the truth about drugs or food or other products they buy because that will piss off their advertisers.
This is the basis of the modern web. It's not a good thing even though it makes a lot of people a lot of money.
