This page covers the online ecosystem — media, communities, fundraising infrastructure — rather than any organization. The organizational strand is on the democratic-socialists page; what is recorded here is the part that operates without one.

Attitudes

The clearest measurable change is in attitudes to the word rather than in membership of anything. Gallup found in September 2025 that roughly two-thirds of Democrats view socialism positively, up from 50% in 2010, while Americans overall continue to view capitalism more favourably.

That is a shift within one party’s coalition over fifteen years, and it is not the same as support for any particular policy or organization.

Scale of the media ecosystem

Pew Research Center’s 2024 study of news influencers gives the shape of the wider space this movement’s media occupy. About 21% of U.S. adults regularly get news from news influencers, rising to 37% of adults under 30; 21% of the influencers Pew analysed were left-leaning; and 77% had no affiliation with a news organization.

The independence from institutions that this movement’s media describe as their distinguishing feature is, on Pew’s numbers, the norm across the whole category rather than something particular to it.

Organization and its absence

The largest membership organization in this space grew from around 6,000 members in 2015 to 43,000 by mid-2018, and is not doctrinally uniform — a charter member describes it as “a big tent — at least on the left”. Bernie Sanders, whose campaigns are credited with the movement’s visibility, is not a member of it.

Those three facts together are the reason this page and democratic-socialists are separate: the ecosystem is larger than the organization, the organization does not speak for it, and the politician most associated with both belongs to neither.

What was removed

The previous version carried a three-phase chronology naming specific subreddits, publications, podcasts and fundraising platforms, with claims about amounts raised and audience sizes — none sourced. It also asserted six categories of political impact, including that the movement popularized Medicare for All, student debt cancellation and the Green New Deal “through sustained online advocacy”, and that it contributed to election outcomes. Those are causal claims about policy adoption and elections; none was sourced and all have been removed.

The founded field, which read 2015, has been removed with the chronology.
