We considered a video about the 'five filters of media', which explained how media stories are filtered out and why some are published while others are not. One of the filters is known as 'flak', which occurs when:

a$.$ The public usurps the role of journalists by becoming involved in reporting $($e$.$g$.$ though social media$)$

b$.$ News organizations fail to produce sufficient public interest and go bankrupt

c$.$ Those who challenge power have theif sources discredited and are pushed to the 'margins' of journalism

d$.$ Media networks fails to make sufficient profit and start creating fictional or sensationalized news stories
