Vox () is a liberal American news and opinion website owned by Vox Media. The website was founded in April 2014 by Ezra Klein, Matt Yglesias, and Melissa Bell, and is noted for its concept of explanatory journalism. Vox's media presence also includes a YouTube channel, several podcasts, and a show presented on Netflix. Vox has been described as left-leaning and progressive. Prior to founding Vox, Ezra Klein worked for The Washington Post as the head of Wonkblog, a public policy blog. When Klein attempted to launch a new site using funding from the newspaper's editors, his proposal was turned down and Klein subsequently left The Washington Post for a position with Vox Media, another communications company, in January 2014. The New York Times David Carr associated Klein's exit for Vox with other "big-name journalists" leaving newspapers for digital start-ups, such as Walter Mossberg and Kara Swisher (of Recode, which was later acquired by and integrated into Vox), David Pogue, and Nate Silver. He described Vox Media as "a technology company that produces media" rather than its inverse, associated with "Old Media". From his new position, Klein worked towards establishing Vox, including hiring new journalists for the site. Klein expected to "improve the technology of news" and build an online platform better equipped for making news understandable. The new site's 20-person staff was chosen for their expertise in topic areas and included Slate Matthew Yglesias, Melissa Bell, and Klein's colleagues from The Washington Post. Vox was launched on April 6, 2014, with Klein serving as editor-in-chief. Klein's opening editorial essay, "How politics makes us stupid", explained his distress about political polarization in the context of Yale Law School professor Dan Kahan's theories on how people protect themselves from information that conflicts with their core beliefs. In June 2016, Vox suspended contributor Emmett Rensin for a series of tweets calling for anti-Trump riots, including one on June 3, 2016, that urged, "If Trump comes to your town, start a riot.
