How has Fox News covered CNN over the past decade? The timeline below shows total mentions of CNN on Fox News since July 2009, showing a relatively steady level of mentions until soaring in August 2015, as presidential candidate Donald Trump ramped up his campaign, then stabilizing in early 2018. Mentions dropped in March 2020 with the spread of the pandemic, but quickly recovered in April 2020 and have steadily increased through present. This is in contrast to CNN's mentions of Fox that have remained relatively stable since early 2018, although CNN shows the same August 2015 surge in its mentions of Fox.
