As I read your article, I flashed on the word, “Rosebud”. A few minutes later, I finally recalled the name of the movie from which that word sprang, “Citizen Kane”. Citizen Kane was the story of William Randolph Hearst and Joseph Pulitzer, as allegory.
I also considered the surreal correspondence between your observations and an ancient article from the Atlantic Monthly. Therein, we find the first of evidence of news organizations treating a press release as “news”. We also find politicians staging events with advance notice of same to news agencies, as well.
That article, ‘The Business of Politics”, was written in 1986. I never would have guessed that such political behavior was predated by 20 years. But with the history of Citizen Kane, the kind of behavior you have observed goes back to at least 1941.
