Are there ways to make money from idle domain other than parking?

When it comes to making money from idle domain, parking is the only choice that all recommend. Do you know any other method to make money from domain?

Developing into websites and blogs could be a quick way to make some additional money from the domain names

I already mentioned in my question, I am talking about ‘idle’ domain. Developing the website is a complete different issue altogether.

Redirecting the traffic of the domain name to traffic sellers or leasing the domain can be a source of revenue
