TL;DR
The title says enough. You could have stopped there instead of burying the point under three tons of verbage. "Money" is what television is made of and made for. Inasmuch as it's the most powerful propaganda device ever devised, and that the nature of that propaganda is advertising, it's always going to be dedicated to proliferating, prolonging and preserving exactly that status quo. There's nothing in the world "liberal" or "conservative" about it in political terms, because nobody makes money on piecemeal ideology. They make money on persuading viewers to buy stuff they don't need, which is the definition of advertising.
That's it, that's all it ever was and all it ever will be.
And to that end they will perpetuate the system as it is, and oppose any challenge to it, which in the broader picture, means "conservative". That's its nature.
You guys who still waddle around bellowing "liberal media" are living in a tinfoil world of paranoia, endlessly bleating mantras that have no basis in an attempt to find your own echo chamber. Y'all think you see a tree and are completely oblivious to the forest it stands in.
You've been spouting your "they make money on persuading viewers to buy stuff they don't need, which is the definition of advertising" bullshit in here for a long time, so it's apparent you never tire of your own stupidity.
In your world of idiocy people never need a new car, they're just persuaded to invest tens of thousands of dollars because they're fools like you. They're persuaded to replace their car's bald tires but without advertising they'd be perfectly happy to ride around on them forever. People never need car, home, life, etc. insurance, rather they purchase it because of TV ads. No one ever needs to paint their house or replace their old leaky inefficient windows, they just get persuaded to do so.
I could go on and forever about various goods or services folks need all the time just like the ones cited above but won't waste my time because to those of us with brains they're obvious everyday needs, not things we're tricked into purchasing because we're dupes to anything and eveything advertised on television.
Happy president Trump New Year!
