Of course, as we know, Faux News chose not to air the hearings. In fact, they were so afraid that their viewers might channel surf, that they went ad-free for the whole of primetime. When they did show any footage they did so with no sound, so that their viewers could not hear what was being said, or any of the witness testimony. They also showed it with a few seconds delay. Why? So that they had time to cut away from the hearings whenever there was documentary evidence being displayed on screen, such as the text messages between Mark Meadows, Sean Hannity and Kayleigh McEnany.
This is the extent Faux News went to in order to try to hide facts, evidence and the truth from their viewers, and happily, it had impact on them... they suffered in the ratings, getting clobbered by MSNBC

MSNBC averaged a whopping (for them) 4.161 million total viewers, trouncing both Fox News (2.957 million total viewers) by 29 percent and CNN (2.617 total million viewers) by 37 percent.
Overall 20 million watched the hearings live and many, many millions more have watched delayed coverage or highlights.
