"Bill O’Reilly’s Fox News career now swims with the fishes.
The conventional wisdom is that after the NY Times exposed a history of sexual harassment  settlements, and two new accusers came forward, advertisers “fled” the show, forcing the hand of News Corp and the Murdochs.
That conventional wisdom is only partially correct — advertisers didn’t flee, they were chased away by the same organized effort as was used against Glenn Beck once upon a time, and Rush Limbaugh in 2012.
Longtime readers will recall my extensive and groundbreaking research into the StopRush operation just after Limbaugh’s comments about Sandra Fluke in 2012, for which he apologized.
I proved then that the operation — at least initially — was a Media Matters astroturfed assault on Limbaugh’s advertiser base, based on a pre-existing plan by Angelo Carusone, then Director of Online Strategy for Media Matters (and now President). 
Supposedly independent groups coordinated their efforts with Media Matters, and then tried to cover it up.
My research led Limbaugh to activate his personal Twitter account to spread the results of my research. 
It also earned me threats to interfere in my employment, although those threats never materialized as far as I know. 
I continued to follow the main group, as it targeted advertisers and eventually imploded from infighting and infiltration. 
The efforts largely failed at causing any meaningful damage to Limbaugh.
Nonetheless, a small cadre of operatives, who often used multiple proxy accounts to multiply their effect, continued to plug away at harassing Limbaugh advertisers over a variety of issues. 
That eventually led Limbaugh, through a spokesman, to push back against the operatives, Limbaugh outs #StopRush Twitter operatives.
