Various media outlets have raised concerns that the mainstream media in the United States have made a concerted effort to downplay, underreport, or ignore the popularity of Bernie Sanders, primarily concerning both his 2016 and 2020 presidential campaigns. Accusations have ranged from explicit media bias, journalistic malpractice, and distortions of information and data. Alternative media such as Rising with the Hill's Krystal Ball and Saagar Enjeti (by The Hill), Jacobin, Vox, Common Dreams, Medium, Fairness and Accuracy in Reporting, prominent YouTube political commentators, among others have published articles, videos, and reports discussing what they see as an alleged media bias against Bernie Sanders. Online communities on websites such as Twitter and Reddit have played a role in documenting what they see as bias in reporting as well. The campaign runs its own media platforms such as the online newsletter Bern Notice, the Hear the Bern podcast, a channel on Twitch, as well as Twitter and Facebook—many of which discuss media bias and what they call the Bernie Blackout.
