Background
Michael Bloomberg co-founded Bloomberg L.P. in 1981 as a financial data firm to sell market data to Wall Street; he launched Bloomberg Business News in 1990 alongside journalist Matthew Winkler, who served as editor-in-chief for decades, primarily to serve the company's Terminal subscribers. The news operation expanded into Bloomberg Television in 1994, Bloomberg Radio, Bloomberg Businessweek (acquired from McGraw-Hill in 2009), and a broad digital presence. Bloomberg transferred his ownership stake to a charitable trust to serve as New York City mayor from 2001 to 2013, then reclaimed it on leaving office. He rejoined the Democratic Party in 2018 and mounted an unsuccessful campaign for the 2020 Democratic presidential nomination; during that campaign, Bloomberg News came under sharp criticism for its policy of not assigning reporters to investigate Michael Bloomberg or his Democratic rivals — while continuing to cover Trump — which critics called a serious conflict of interest and which prompted the Trump campaign to revoke Bloomberg News press credentials. John Micklethwait, former editor-in-chief of The Economist, has led the newsroom since 2015. AllSides rates Bloomberg as 'Lean Left' (with low confidence as of mid-2026), while Media Bias/Fact Check rates it 'Left-Center.' Michael Bloomberg's status as one of the largest donors to Democratic causes and candidates is widely cited when assessing the outlet's independence from its owner's political interests.
