Media hegemony

Media hegemony is when one kind of media, like news programs or movies, has more influence over what people think than other kinds of media. It's like when one person or group has power and control over many others. In media, it can make people believe in certain ideas more than they should because they hear the same thing over and over again. For example, if all the news programs talked about how one political party was better than the other, people might start to only see that party as the best one, without considering other options.
