In some countries, the media is controlled exclusively by large companies; in others, it is the government that has this control. Often, in war situations, one of the first casualties is the media, which is seized by one group or another. This gives some support to the idea that the media is a source of power and control.
Whoever controls the media also ultimately controls what is published or broadcasted and what is omitted. Depending on their feelings about the matter, they can also add a particular prejudice or bias to their coverage of specific news stories. This is not a new problem, although the issue is perhaps more pressing now that the Internet and play-TV have enabled these messages to be disseminated even further.
However, we should remember that readers have their own ideas and opinions. You can control what is printed, but you cannot control your readers’ opinions. I think the only positive here is that, nowadays, people seem to be much more cynical about what they read in the press or hear on television. In particular, when it comes to the tabloid press, people know they must take what they read with a grain of salt. In other words, they read knowing they may be being lied to. Perhaps it is an even greater concern that we have become so accepting of this form of censorship.
The only thing that can be done to alter this situation is for the government to regulate the industry so that there is no longer a monopoly on media ownership. This also means that they have to allow and support a totally free press, even if this means the government may be criticized or ridiculed within its pages.
