Answer:
This type of Media Bias is called Bias by Omission.
Explanation:
Bias by omission – leaving one side out of an article, or a series of articles over a period of time; ignoring facts that tend to disprove liberal or conservative claims, or that support liberal or conservative beliefs; bias by omission can occur either within a story, or over the long term as a particular news outlet reports one set of events, but not another. To find instances of bias by omission, be aware of the conservative and liberal perspectives on current issues. See if both the conservative and liberal perspectives are included in stories on a particular event or policy.
1. Night of Long Knives (1934)
4. Kristallnacht (1938)
3. Auschwitz opens (1940)
2. Wannsee Conference (1942)
Now a couple of these were a little hard to place, for Auschwitz, I simply put the year in which it was first operational. I've placed the years by the side of each for your reference.
Whats the rest of the question?
The Gulf of Tonkin incident, also known as the USS Maddox incident, drew the United States more directly into the Vietnam War.
