Does this video show "the media" is colluding to control a narrative by giving anchors identical scripts? No, that's not true: The video, from 2018, shows how conservative-leaning Sinclair Broadcast Group was found to be requiring its TV news anchors to recite the same promo script. These widely distributed scripts were contained to Sinclair and were not aired by anchors of other broadcast companies.
The implication that this video collage shows media collusion appeared in an Instagram post (archived here) where it was published by @mitch_aguiar, a mixed martial arts fighter, on November 15, 2020 with the hashtag: #DefundTheMedia. The caption opened:
WAKE UP AMERICA
For those of you who still don't understand what's going on and why myself and so many other Veterans and Patriots are pissed off let me help inform you. America is under attack and we can see it plain as day! The media and social media control the narrative by spreading propaganda and instilling fear so that you sheep willing give up your freedom. Pathetic! Prepare yourselves people.
This is what the post looked like at the time of posting:
