Newsweek has a clear Left bias. AllSides shifted Newsweek's bias from Lean Left to Left following a May 2020 independent review by an AllSides editor.
Newsweek's content heavily employs slant, a type of media bias in which the publication's writers tell only the side of the story or choose to highlight only information or story topics that favor one side; in this case, Newsweek's content favors liberal or left-wing perspective and policies. Newsweek omits right-wing viewpoints, perspectives, and stories that may be deemed important to those on the right.
Newsweek is an American weekly news magazine founded in 1933. According to Wikipedia, "Newsweek was acquired by The Washington Post Company in 1961, under whose ownership it remained until 2010. Between 2008 and 2012, Newsweek experienced financial difficulties, leading to the cessation of print publication and a transition to all-digital format at the end of 2012. The print edition then relaunched in March 2014 under different ownership."
