"ThinkProgress" was founded in 2005 by Judd Legum, a lawyer, who ran the site until he left in 2007. Faiz Shakir edited the site from 2007 until 2012, when Legum returned as editor-in-chief. Legum left the site again in 2018. "ThinkProgress" described itself as "editorially independent" of the Center for American Progress (CAP) and CAP Action. In its early years, "ThinkProgress" included a daily newsletter that contained a recap and analysis of major political news and the blog "Wonk Room", which was published until 2011. In that year, the site was redesigned to offer sections organized by subject matter, and other CAP Action blogs were consolidated into the site. The site was then divided into sections covering climate, economy, health, justice, LGBT, world, culture, sports, politics and features. In 2017, the site's organization returned to a less segmented presentation.
