The answer is PROPAGANDA.
Propaganda refers to information or images published that presents one part of the "whole story" or real situation with the purpose to influence people's point of view and get a certain emotional response.
An example of propaganda is an audio-visual material broadcasted on TV displaying a set of great achievements in public transportation made by a political party. This propaganda aims to touch people emotionally and receive more support for the party. However, this information is only showing "one side of the story", it says nothing about people's chance to peacefully enjoy the transportation due to the lack of security and the high-criminal rate.
