Blockchain technology and Bitcoin are 2 related but different things....
Yes Bitcoin uses a blockchain *but* it is restricted to mainly being for monetary transactions - NOT general records keeping.

That said, there are many many real-world uses of blockchain technology that ARE used for records involving that involve tracking food production & distribution, various electronic device production, municipal lighting, long-haul trucking, etc. Publishing is just another variant of that. The key point here is that the blockchains used are tailored to a specific purpose and none of them have anything to do with BTC.
