If you have an idea for a Game Show or a TV Show the first thing you must do is register your work to get copyright protection.  You do so by utilizing one of the links below.

   Writers Guild of America West

   Writers Guild of America East

   TV Writers Vault

Once you have your work registered you need to find a production company that will develop your work and sell it to a Network.  You cannot directly contact the Network or Production company and sell your idea.  They only deal with Agents who specialize in bringing them new ideas.  Therefore, you will have to find an Agent you trust to do the work for you.  You could spend a great deal of time and effort trying to find one. 

The best way to promote your work is through an online service setup to bring Production companies in touch with new ideas. The TV Writers Vault was created for this specific purpose.  In addition to the registration service they provide they also help you to put your work before Production companies that use the service to find new ideas.
