Founded2018

Ad Fontes Media, PBC is a public benefit corporation dedicated to assessing news source reliability and bias to combat misinformation and promote media literacy. Founded by patent attorney Vanessa Otero, the company is renowned for creating and maintaining the Media Bias Chart®, an interactive tool that plots news sources on a spectrum of political bias (left to right) and reliability (original fact reporting to opinion or fabricated content). Their methodology involves a multi-analyst rating system, considering factors like expression, veracity, and headline accuracy. Ad Fontes Media aims to empower news consumers to make informed choices about their media consumption and to encourage a more balanced and factual news ecosystem.
