Say I want to encode The Lord Of The Rings in HD but I dont want anyone to know that information is being hidden somewhere. So I launch an ad campaign to people of certain demographics expecting them to, eventually, type certain words into a search engine that I could, after some time, use to decode data that has been hidden in similiar, grass roots, ways?
The whole LOTR trilogy I bet you could be done by someone clever enough but I guarantee a few bytes could be done. Which means you could essentially hide information in peoples minds.
I guess my question is what are alternative ways to store binary information?

It is called Steganography: https://en.wikipedia.org/wiki/Steganography

I don't know that this implies hiding information in people's minds. The point of steganography is to conceal the information to be retrieved later after some processing. If you're just watching a movie and there's info hidden using traditional steganographic techniques, you wouldn't notice it at all, subliminally or otherwise. You could try interspersing frames within the movie that might register visually to the watcher without their conscious knowledge, but this would probably limit you to imagery alone and there wouldn't be a guarantee that you could get your point across consistently among viewers. I'm also not an expert in any of this, so I can't tell you what current or prior research says. I'm sure it's been tested though.
Edited to fix typos.

You would have to manipulate, or at least predict, Google's ranking system, details per result, and so forth.
