23. PROFESSIONAL COMMUNICATORS. It would be unfair to suggest that all communications media and all communicators are involved in this noxious trafficking. Many communicators retain high personal and professional standards and seek to fulfill their responsibilities with a strong commitment to moral norms and the common good. Their efforts - especially the efforts of those who seek to provide wholesome family entertainment - deserve recognition and encouragement. We urge these communicators to join in formulating and applying ethical codes for the communications media and for advertising which respect the common good and promote sound human development. Such codes are particularly necessary for television, which makes it possible for images to enter directly into the home where children may often be alone and unsupervised. Effective self-control is always the best control, and self-regulation by the media can be the first and best line of defense against those who would corrupt the media and society itself by seeking to profit from pornography and violence. We also urge communicators to help make better known through the media the steps which can be taken to stem the tide of pornography and the exaltation of violence in society.
