Regarding manipulated broadcasts, a former journalist turned media professor once said that advertising is the most truthful thing in the media

‌
Not to mention variety shows,
even news broadcasts or newspaper articles
have an immense amount of conflicting interests behind them.
There are issues with advertising budgets at the corporate level,
and there is also a lot of bias due to individual journalists' ambitions, corruption, or personal preferences.
He said that being upfront and saying, "This is an advertisement" or "The purpose is marketing,"
is actually the most truthful approach.
