According to the First Amendment of the U.S. Constitution (source #2), it clearly states that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances." As it is stated in the constitution, limiting the media would be breaking the ultimate rule of our nation.
According to the text book (source #6), "The First Amendment does not mention electronic media." Maybe that is why censorship exists today when we have freedom of speech and press. Since television and radio stations are considered an "electronic" media, the Federal Communications Commission regulates the electronic media. In 1996, Congress passed the Telecommunications Act. The Act included two provisions that allow for some government control of the content of the media. One required that television manufacturers include a "V-chip" in each set. Another was known as the Communications Decency Act which prohibited the transmission of indecent or patently offensive materials on the Internet in such a way that minors could access those materials. Ironically, in 1997, Supreme Court stated that the Act restrained too much protected adult speech and decided unconstitutional. Censorship has once failed, and I believe that it will keep failing in the future.
Although I strongly believe that media violence should be allowed, public opinions strongly support the censorship. The National opinion poll took a survey regarding the entertainment media and found out that "the American public believes the entertainment media are too violent, offensive and harmful to society" (source #4). Study shows that majority of 53% believe that viewing portrayals of violence in television, books, films and newspaper stories makes people more likely "to do something violent.
