The correct answer to this open question is the following.
The role of own beliefs, ideologies, and worldviews in media reporting has hurt the objectivity that is required for a true journalist to do its job of reporting the news without a bias.
Media can reach far places where conventional citizens can tune the news channel to be informed. They deserve objective information, without any bias to know the truth. People are tired of media taking sides. That is not part of their job, although they have been criticized in the past to serve the corporative interest of the people who own those news companies.
Supposedly, mass media companies hire experts on different subjects who can cover the news and express their opinions to invite the audience to reflect on the delicate topics, but many times the reporter is following a particular agenda when reporting the news.
Let's have in mind that mass media is the means of communication that transmit information of public interest such as television, radio, printed press (newspapers and magazines), and all their digital formats. So mass media has a huge responsibility because it reaches large audiences in the country and around the world.
