Answer: broadcasting; narrowcasting
Step-by-step explanation:
With technological advancements in the marketing landscape especially on the internet, companies are now able to target individuals better based in their preferences and patterns of trade.
Search engines and websites for instance are able to save our data as we browse and so are able to infer what products we might be looking for and then recommend a place to get it. Companies are capitilizing on this to engage in more narrow methods of advertising that appeal to the individual consumer as opposed to broadcasting on a large scale and hoping that those who like the message will respond.
