As mass media technology advanced in the early twentieth century, courts began experimenting with allowing photography and radio broadcasts of court proceedings. Following the media "circus" surrounding the trial of Richard Bruno Hauptmann for the Lindbergh kidnapping, broadcasts from federal courtrooms were banned by Rule 53 of the Federal Rules of Criminal Procedure. Additionally, the American Bar Association adopted Judicial Canon 35, which prohibited the use of motion or still cameras in the courtroom and was codified into law by the majority of states. On the other hand, no state or federal court prohibited the publication of courtroom sketches and courtroom sketch artistry continued.
