Blockchain would not be the right tech if you don't need decentralised trust.
Write once media on a server is what you want.

Blockchain is only useful in a decentralized + adversarial context where there is a need to remove one-another's ability to game a given system. And even then, it doesn't imply a perfect security around it. Since it won't stop theft, breach, scams or other vectors.
How does that solve this problem:
>[company will] go out of business and take down the servers with it
Maybe some sort of globally distributed time-stamping mechanism? Oh hey look, it's a blockchain.
If you aren't in an adversarial context with multiple publishers, you don't need blockchain.
How is this published? On a single server somewhere? What country would you put it in? A friendly one I hope. Also one that won't block access to other countries that it might have petty disagreements with in the future. It might be a good idea for it to be replicated across a number of servers across the internet. We call those "nodes" in the blockchain space.
Mirrors existed long before blockchain.
Like publishing merkle tree hash in a few daily newspapers.
If you want to proof you didn't temper with the historic data, publish a daily hash in some newspapers.
