Ad Fontes Media is a Colorado corporation aiming to make “news consumers smarter and news media better.”
Their flagship product is an interactive media chart that quantifies and sorts news outlets based on their tendency towards liberal or republican-biased content. A new 2020 version of this chart was released late last month.
The chart operates on two axes — vertical describes the trustworthiness, while the horizontal shows left-right bias.
You can find a basic version of the chart below and an interactive version on the Ad Fontes Media website.
