The Federal Communications Commission is fighting a ruling that could allow more profanity on television.
In July 2010, a federal appeals court ruled that the FCC's "fleeting expletive" policy violates the First Amendment.
The policy has been in place since 2003 and fines broadcasters for allowing profanity. But Thursday, the FCC filed an appeal to defend the rule.
That announcement is being applauded by the Parents Television Council.
They said, "The importance of the broadcast decency law has become abundantly apparent as the broadcast networks demonstrate their desire to push ever-more graphic content at all times of the day."
