Agenda Setting Theory (AST) is a phenomenal theory which is being used by all types of media to create and spread awareness about salient and current affairs issues. The theory is used by media channels to build importance about an issue or a matter which the audience then perceives it to be more important than others. Since it is shown over and over again by news channels, the audience takes it as the most important issue at that time and perceives all other news as unimportant. The AST is used in news channels, radio, internet media, social media websites, etc.
Social media is a tool which uses computer related tools to allow people to create information, share information, and comment and forward information in their network instantly anywhere in the world with internet access. The content can be anything from news to personal information, personal pictures and videos, etc. Media channels often have internet channels for global customers who can access their information and news through their website, and hence it is possible for anyone to share any news information to any other personal anywhere in the world. The irony of the fact is that people do share mostly what is available in the website of a news channel, which means that they will mostly be able to share what the news channel chooses to display through their social media channels. The news shown by the news channel is mostly instantly done, but they build up the same news and make it into a large story by displaying them on their website which informs the audience more about the matter and issue. This can give detailed information to the audience and they can equip themselves with the news and decide their level of importance. However, if the news channel is artistic and creative in forming news stories and adds a lot of personal interpretation, the news story can actually change from what it originally was. Besides, if the same news story is being run by the news media through all mediums, there is nothing else for the audience to watch and they supposedly take that news matter to be most important at that current time and leave all other news behind, even though they may be specifically be of importance to them individually, so social media is as powerful in raising an issue, as it is harmful in raising the issue for wrong reasons and harming the victims involved in the matter.
