Paul Graham article on the public relations industry.

I read somewhere that there are 7 professional PR people for every 1 journalist. Their sole focus is to get content in the media that benefit their clients.

> Media bias is largely demand-driven, not supply-driven

The vast resources spent on surveillance and psychologically manipulative feed optimization, are an example of psychological demand creation. Using the original demand to be connected to friends and family, as the ingress for massively successful businesses based on manipulating people.

Referring to that as demand driven market is ridiculous.

Social media isn't a simple demand-driven or supply-driven market.
