I believe the change happened when the FCC removed the "public service" requirement from the licensing process. Prior to that, news was not a "profit center" but a public service, operated at a loss to fulfill the requirement.
I seriously doubt that newspapers and television ever operated at a loss. That's why they sell advertising. Newspapers existed in the Old West, and the owners made a living by selling advertising. The same holds true today.
I am simply tired of movies and news that cater to basically illiterate 15-year-old boys.
