His first show brought in over 26 million “video views,” which is a Twitter metric that records a view as anyone who watches a video for more than 2 seconds. While the metric’s reliability has been questioned, it has nevertheless declined significantly since the show’s launch, with Carlson’s most recent show only getting 3.8 million video views, marking a drop of 86 percent.
Most of these graphs look like f(x) = 1 / x for exactly that reason, and given how little I’m hearing about the show on non-Twitter social media, I have no reason to doubt it would be the same here.
The Swanson’s heir can bankroll a lot of episodes though, so he might not give up as easily as other “media personalities”. I think it will still be a blow to his ego though.
