What to Do with the Idea
Thoroughly research existing programming and news stories about shows currently in production. The most important aspect of an idea is that it is original. As well as examining the HBO website, visit other television network websites and examine their programming lists. Also use keywords from your idea and conduct Internet searches.
Develop the initial idea into a format that is accepted within the film/television industry. A two- to five-page synopsis, or treatment, needs to be written adhering to specific guidelines. Software programs such as "Final Draft" can be used to assist with this, and free demo version downloads are available for both the Mac and PC.
Copyright the idea so it is protected at latter stages of development. Consider joining an organization such as the Writers Guild Of America for a fee of $20 for five years; membership protects all work that is registered, which essentially gives you the same protection as registering your work with the Library Of Congress.
In order to have the idea presented to HBO or other networks, an online company such as the TV Writers Vault can be used to bridge the gap between you and the network. This particular company offers a 30-day membership for $39.99, but for multiple presentations, the cost increases. It offers information about the industry from an insider point of view.
If this approach is not working and the idea has not been presented to HBO or another desirable network, the other way to proceed is to hire an entertainment attorney or agent and present the copyrighted treatment. Be aware that this is an expensive route; according to entertainment attorney Mark Litwak, "The cost for entertainment attorneys is usually $250 to $450 an hour."
