The Communications Act of 1934 is a law signed on June 19, 1934 by President Franklin Roosevelt. The act replaced the Federal Radio Commission with the Federal Communications Commission as well as transferred regulation of telephone services from the ICC to the newly created FCC.
One section of the law, 230, was created as part of a 1996 update to the law in order to include references to the Internet. This section provides a legal "safe harbor" for content systems that host third party user content. Several prominent conservative legislators have taken aim at section 230 of the CDA as a way to resolve Shadow banning and censorship of conservative voices by online platforms. Facebook is an example of this.
