For example, one key element of society is the media. Before the internet, if an individual person wanted to broadcast a message, they had to own or be able to persuade a media organisation to broadcast it, or they had to into the street and start shouting! However, the internet has caused a shift in power, because social media and video streaming services like YouTube have enabled people to broadcast their own messages and interact with global audiences. Online content is still controlled to an extent by moderators, who enforce the service owners’ policies on what kinds of content should be published. What users see online is also determined by the programmes that control what stories and videos are promoted to their reading lists and viewing lists. These decisions can be based upon users’ browsing history or the browsing history of friends linked to their online profiles. In some cases these decisions depend on whether individuals and organisations have paid to promote their information to users. C.
