NOTE: As of November 2019, Bloomberg News is engaging in apparent bias by omission in its 2020 election coverage after its editor-in-chief stated it would not investigate Michael Bloomberg or any other Democratic presidential candidates. AllSides is monitoring this closely, and may change our bias rating following more thorough review of Bloomberg content.
Years ago, AllSides rated Bloomberg as having a Lean Right media bias, but a majority of AllSides users disagreed. Following a review, its AllSides Media Bias Rating™ was changed to Center in July 2014.
The results of an October 2013 AllSides blind bias survey also reflected that a majority of respondents rate Bloomberg's reporting as Center.
However, as of Nov. 2019, Bloomberg admits that it engages in bias by omission with a Lean Left bent. Mike Bloomberg, New York City mayor and founder of the financial software company that owns Bloomberg, officially entered the 2020 Democratic presidential race in Nov. 2019. According to a memo sent to editorial and research staff obtained by CNBC and verified by a Bloomberg spokesperson, Bloomberg News announced it would refrain from investigating Mayor Bloomberg and his Democratic rivals.
“We will continue our tradition of not investigating Mike (and his family and foundation ) and we will extend the same policy to his rivals in the Democratic primaries. We cannot treat Mike’s democratic competitors differently from him,” Editor-in-Chief John Micklethwait said in the memo.
In Dec. 2019, President Donald Trump's campaign announced it would stop credentialing Bloomberg News reporters for rallies and other events until the outlet resumed investigating Democratic candidates.
Mike Bloomberg is founder and 89% shareholder in Bloomberg LP, the financial software company that owns Bloomberg News.
More About Bloomberg
Bloomberg L.P. is a privately held financial, software, data and media company founded in 1981 in New York City. It initially began as a computerized system founded by Michael Bloomberg with the help of Thomas Secunda, Duncan MacMillan, and Charles Zegar, designed to provide real-time market data and analytics to firms on Wall Street. With the help of an ownership investment by Merill Lynch, the company was able to develop the Bloomberg terminal computer system in 1983.
Bloomberg currently provides news in a variety of formats, including a wire service, a global television network, digital websites, a radio station, newsletters and magazines. With a focus on business and economics-related topics, Bloomberg News has redefined itself to become the “chronicle of capitalism,” as editor-in-chief John Micklethwait indicated in 2015. Bloomberg’s main source of revenue remains the Bloomberg Terminal, which offers financial software tools to companies and organizations on Wall Street.
