Question

who controls the media and why​

Answer 1

Explanation:

Primarily editors. To a lesser extent publishers and producers. However owners (sometimes owners and publishers are the same) have an indirect influence in as much as they have significant control over policy and hiring. Journalists develop stories and reports but it is up to the editor whether to publish/air them or not and they can ask for changes. From time to time editorial decisions will be reviewed by the owner when the stakes are high as for example when the Post published the Pentagon Papers. Katherine Grahame gave the final approval to Ben Bradley, the editor.
