I feel like politics nowadays is not so much a fight between politicians, but between corporations with conflicting interests and the handful of people at the top behind them, and the parties paying them (including foreign powers).
This I'm afraid isn't true, though it may feel like it.
None of the free-to-air TV channels are owned by News Corp, which remains the purview of BBC and ITV in the main. It has minimal investment in radio stations. It has The Sun, The Times and Sunday Times. It used to have the News of the World.
It doesn't have the Mail, Express, Independent, Guardian, Mirror etc.

Ultimately, it is and always will be a powerful few who have too much against the many who have too little.
If your were instead talking about the coorporations they lead, they have been trillion dollar companies for a long time. And Apple is enjoying ts best years.
Sinclair Broadcasting owns local stations, most likely at least one near you: http://sbgi.net/tv-stations/
Scripps I believe is a bit smaller, but also owns a lot of local stations: https://scripps.com/our-brands/local-media/
So if Sinclair and Scripps both run the same newswire story, for instance, that is a country full of people getting it through their local -- often "most trusted" -- news station. A lot of stations get the "final say" on what does and doesn't run, but sometimes they do not.
