Answer:
Biased
Step-by-step explanation:After watching any of these broadcasters, ABC, CBS or NBC it is clear that they, as powerful mass media, sometimes take sides when speaking about some particular subjects, especially regarding political or economical. This is of course unethical because one the key elements at the moment of delivering information to the public it has to be unbiased, transparent and with the sole purpose of informing and analyzing.
When the speech engages with persuasion it clearly is taking sides because is looking for creating in the public not the objective analysis of information but the subjective point of view based on the intentional and unethical persuasion exercise executed on the part of the mass media. Regarding the question of being able to be persuasive without being informative the answer is yes.
Most media, politicians, companies just to mention a few are highly persuasive with biased information, marketing resources, and different strategies that people very easily “buy” and “believe” because most of the time such “persuasive information” is so well delivered that people do not second-guess it or even try to structure an educated guess of the information recived.
