Who do you pitch a reality dating show idea to and can you actually get paid if it gets made?

I have an idea for a reality dating show concept and I’m curious how this actually works in the industry.

If someone has a strong concept for a reality show, who would you even pitch it to? Networks directly? Production companies? Agents?

Also, if a show actually got made from your concept, would you receive any kind of payment or credit for the idea, or do they usually just take the concept and run with it?

I’m trying to understand how people go from “idea” to actual show and whether creators typically stay involved or benefit financially.

Would love to hear from anyone familiar with how reality TV development works.
