Fake-news meaning

The posting of false information on Facebook, Twitter and other social media sites can cause problems for just about anything from politics to community affairs to the reputation of an individual or organization. As with user-generated content, there is limited oversight or vetting, although starting in 2018, the media companies have attempted to address this issue. Nobody envisioned that major disruptions would be a consequence of social media when they took off in the mid-2000s. See deepfake, fake website, fake fans, cyberbully and social media.
Misleading information or outright lies presented as factual reporting. Created with the intent to deceive and confuse, making it difficult for people to know what is true and what is false.

Originally sensational stories spread on social media, fake news has made its way into mainstream media, often with a political agenda.
