Fact-checking instruments

Instruments for fact-checking

Fact-checking site	Financing	Bias	Association
AllSides	Subscriptions and services for the 23%, advertising for the 4%, client services for the 72%. The data refer to 2022	AllSides maintains a multi-partisan perspective on facts, reflecting the political views' diversity of its funders (https://www.allsides.com/blog/is-allsides-biased-about-biases-partners-owner-funding).	AllSides works with Harvard University, Brave Software and USA Today among the others listed on their websites as clients.
Ad Fontes Media	Ad Fontes Media is financed through the sale of services and products, but also raised money through Crowdfounding. They received support from the Glen Nelson's Center Horizon Fund (which finances start-ups) and from Gaingels (https://adfontesmedia.com/about-ad-fontes-media/).	Biases are present in the chart they provide about the positioning of the media, but Ad Fontes Media attempts to mitigate the team's biases, even if the founder publicly defines herself as of left-of-center political views (https://adfontesmedia.com/is-the-media-bias-chart-biased/).	Glen Nelson's Center Horizon Fund and Gaingels, which financed the project are of lean-left political views.
Media Bias / fact-Check	This network defines itself as independent since it is financed through the membership of the readers (65%). However, they are also being funded by advertising through Google Adsense and Snigel (35%), donations account for only 5% coming from Patron and Paypal (https://mediabiasfactcheck.com/funding/)	Media Bias / fact-Check uses a scoring system to determine the bias of a media outlet/piece of news, therefore they strive to be as more objective as possible (https://mediabiasfactcheck.com/frequently-asked-questions/).
The Trust Project
Ground News	Ground News claims to be funded by private investors without links to corporate media, big tech, or government affiliations (https://ground.news/frequently-asked-questions).	Ground News uses a scoring system to determine the bias of a media outlet/piece of news, therefore they do not publish original contents in terms of authorship and aim at giving the readers tools to assess the credibility and bias of the media they read (https://ground.news/rating-system).
Snopes.com	Advertising revenue and generous contributions from readers	Snopes is defined by AllSides as a lean left fact-checking institution (https://www.allsides.com/media-bias/fact-check-bias-chart). To address the question they published a post with the diverse opinion on Snopes by their readers (https://www.snopes.com/2015/04/17/eye-of-the-beholder/).
FactCheck.org	FactCheck.org is financed by the Annenberg Public Policy Center internal to the Pennsylvania University which was founded by Walter and Leonore Cohn Anneberg, who was a UK ambassandor during Nixon presidency (https://en.wikipedia.org/wiki/Leonore_Annenberg).	A part from the Annenberg Public Policy Center, additional funding has been coming from the Flora Family Foundation and in 2010 they started receiving donations from private individuals (https://www.factcheck.org/spindetectors/about/).	AllSides places FactCheck.org in lean left bias following their evaluation (https://www.allsides.com/media-bias/fact-check-bias-chart).
