The United States' Federal Communications Committee (FCC) is the governmental body that oversees all radio and TV stations to make sure that the stuff that is getting aired is "proper" for people to hear.
"Created by Congress in 1934, the FCC has myriad responsibilities. On broadcast television, the FCC enforces the federal laws that effectively preclude explicit content from appearing on over-the-air programming: no obscenity whatsoever, while indecency and certain profanity are only permitted between 10 p.m. and 6 a.m," said Jamshid Ghazi Aska.
The FCC standards of rules and regulations of what goes on over air are particularly vague, misleading and outdated for where we are in 2012. For a quick example, you can say "Penis. Vagina." or "poop" on air, however "Penis and Vagina." and "I'm pooping" are HUGE radio no-nos that can cost thousands of dollars to the station and it's licence holder.
Is this ethical? Can a governmental entity act as a smut police safeguarding our children from dirty things like sex and poop?
These rules were put in place during a time where "family-oriented programming" were forefronts in american values -- I'm not sure if, as a country, America has become less family-oriented or more realistic. In a communitarian sense, these regulations are pretty unethical -- they essentially safeguard against free-speech programming and make Disc Jockeys weary of everything they say that can incense the FCC.
Speaking of incensing the FCC, the minimum dollar amount they can fine a station when they make ANY infraction, let it be a quick "I'm pooping" on-air or forgetting some sort of unimportant paper in their public file to forgetting to give a Station ID at the top of the hour is a cool $10,000.
When a station, especially a non-commercial, student-run station can be charged over half of their YEAR'S operation budget, a small infraction can easily put a station off-air permanently.
The FCC knows this, and readily enforces their sanctions like no other. Is this ethical?
DOUBTFUL. In the 21st century, it's hard to maintain relevancy when you are going around policing anytime someone says "tit" on air. In my opinion, these fines are not their to necessarily reprimand a great wrong, but instead acts as almost a power move by the FCC.
It would be "Fucking Brilliant" if the FCC got with the times.
