Media Matters reports:
Fox News’ role as a secondary communications shop for Donald Trump and host Sean Hannity’s advertiser troubles are apparently starting to affect the network’s bottom line. In September 2017, Fox News’ ad revenue dropped a whopping 17 percent as compared to September 2016, while CNN’s dipped 1 percent and MSNBC’s increased 2 percent.
The relative disproportion of Fox’s 17 percent loss means that it can’t be attributed merely to normal market fluctuations. If the market as a whole was the primary cause, then you’d see larger changes at CNN and MSNBC too. Accordingly, this massive loss indicates that there are other factors unique to Fox that are driving the drop.
The single biggest factor likely driving this decline is the fallout from advertisers leaving Sean Hannity’s program. Yes: Sean Hannity is losing advertisers! And, as we have seen before, when advertisers start leaving, revenue begins to decline.
The Hannity boycott movement gained enormous steam over the summer due to his repeated flogging of the Seth Rich conspiracy claims even after his own network publicly backed away from the story.
