Advertising revenue of misinformation publishers worldwide 2021
It was estimated that, in 2021, websites that repeatedly published fake news generated 2.6 billion U.S. in advertising revenue worldwide. In the United States only, the figure stood at 1.62 billion U.S. dollars. The revenue comes from programmatic advertising, whose buying is an automatized process, and advertisers have little influence on where and around what kind of content their ads are placed.
