What percentage of content on the Internet—memes, videos, blogs, etc.—are published with the explicit intention of shaping your opinion, or nudging your actions, but are disguised to be completely innocuous?

Take out foreign actors. Just homegrown efforts. Whether that be our government, corporate interests, news media, etc.

1%? 20%? What topics would be most important to them?

I don’t have a point other than just thinking about that question makes me more aware of propaganda. Because whatever the percentage, it’s non-zero.
