Why you shouldn't put the DGA logo in your end credits
We occasionally get requests to add the DGA (Directors' Guild of America) logo to an Endcrawl project.
However, the DGA expressly disallows this:
The DGA logo is a registered trademark of the Directors Guild of America, Inc. and the Guild does not permit its usage in any manner in credits.
We strongly caution against using any trademarked logos or other intellectual property without the express permission of the rightsholder.
For more detail, please visit this page on the DGA website, click on "View: Screen Credits", and scroll to the bottom of the page.
