For those who don't know, the Bat Embargo was created in 2005 designed to ban or limit the use of Batman related characters in the media (For example, the could only be one version of Batman or Wonder Woman at a time). This is why Riddler and Scarecrow were banned from being in Justice League Unlimited and Batman not appearing in Smallville. This even applies to character not created from the comics like
Renee Montoya who was not allowed to be in The Dark Knight (has been pointed out this was not true).
A similar one was created for Wonder Woman, hence why Wonder Girl was banned from appearing in the Teen Titans animated series and why she was nearly banned from appearing in the Justice League animated series (the creator were able to convince WB to allow her use but other shows have not been so lucky).
Do these embargo's still exist or have they been altered greatly? Can the CW TV series use Batman and Wonder Woman characters freely or are they still limited?
