Of all the investments in conservative media made by the billionaire Mercer family over the years, none have been as prominent, or as public, as their minority stake in Breitbart, the flame-throwing, once wildly-influential media brand founded by namesake Andrew Breitbart and guided to its shitkicking apotheosis by former C.E.O. Steve Bannon. But these days, compared to its 2016 heyday, Breitbart has far less influence in conservative politics, and fewer people appear willing to pay for merchandise. Meanwhile, after various Facebook algorithm changes and the faded rubbernecking of the liberal elite, advertisers don’t quite seem to lust after whatever audience remains. Breitbart was also the target of a viral campaign that pressured blue-chip companies to remove their programmatic ads from Google Ads, compounding their financial woes.
