Most of this started with the Telecom Act of 1996 which "Deregulated" media outlet laws that forbade any one person/entity from owning too many outlets in a given region here in the US. This allowed for and all but forced localities to make their own news, but once Newspapers and News Channels began to "merge" so did their outlooks. We've all seen the vid on YT of the "Local News Anchors" reading their Corporate Propaganda spiel from the single company that owns Dozens of "local news outlets".

Obama then put the nail in the coffin when he over turned a law forbidding the use of US State-Sponsored Propaganda here at home. We have to fight "Terrorism", remember, so we "have" to deploy Propaganda on the populace, or the Taliban wins, amirite? That's how we got amazing "Media Resources" like Reddit, Twitter and Tik-Tok that work hand-in-glove with the US Feds and various other "Foreign Entities" to "shape the media narrative".

See history of great folks like Ghislane Maxwell and her Daddy and their ties to very intellectually Liberal and level-headed outlets, like Reddit, which never use bots, mods, algorithms or literal paid brigades of "Commenters" to slide threads into oblivion.

Prove me wrong :)
