I suppose everything from: normal advertising; to government advertising [propaganda]; to any industry where PR is important [e.g. oil, healthcare], aka corporate propaganda. And the interests of governments and multinational corporations reach far, from the environment to finance to workers rights. Similarly, their advertising reaches just as far, much further than just "vote for us" or "buy from us".

If I sound like a cynic it's only because the world made me that way.

There are a few countries that aren't exactly friendly with the Western world and know our democratic systems have a weakness in that you can rile people up and get them to vote against their own best interests, damaging their own country.

The internet and social media in particular are valuable tools for this strategy, so it would be insane for them not to use it to its full potential. And that means endless bots manipulating the narrative.
