Under YouTube's 2016-2019 changes to its recommendation engine, the most recommended channel evolved from conspiracy theorist Alex Jones to Fox News, especially Fox's "unabashedly conservative pundits". Fox News was said to fit into YouTube's "algorithmic sweet spots": being "rubber-stamped as an authoritative source" but having "partisan headline" videos. Leading up to the November 2020 U.S. presidential election, data showed the most frequently recommended Fox News videos were from "its pro-Trump prime-time shows that often attacked Democrats and sometimes spread unreliable information about voter fraud and the coronavirus". Following the 2020 election, "fringe, right-wing news channels aggressively pushing unfounded claims of widespread voter fraud" saw a greater percentage increase in views, while Fox News saw a decrease despite YouTube treating Fox as a "promoted, authoritative source". After the 2021 storming of the U.S. Capitol, YouTube took less aggressive action than other major social networking platforms toward Donald Trump, with CNBC noting that YouTube has historically taken a more hands-off approach to moderating content. Typically, YouTube has maintained a low profile as Facebook and Twitter took the brunt of backlashes in times of crisis, such as Russian interference in the 2016 elections and after the 2021 Capitol attack.
