Regulations on differen media
• Broadcast vs. Print Media
– Radio and TV are more closely
regulated by government
– Over-the-air broadcasts reach the
public more easily
– for printed materials, people must be
literate and make effort to find them
– broadcasting industry must work to
protect children from inappropriate
language and images
Exploring the Internet (cont.)
• Internet
– In 1996, the court in philadelphia ruled that the Internet was
more like the print media than the broadcast media.
– The courts have given books, magazines, newspapers, and
other print media more freedom from regulation than other form
of mass communications
– Therefore, the Internet enjoys this high level of freedom
– First Amendment attorney Robet S. Peck wrote:
The U.S Supreme Court has concluded that cyberspace receives the
highest level of protection that the First Amendment affords. As a result,
the same considerations that apply to printed words and images apply as
well as the electronic word and the digital images.
Concerns on Cyberspace

Conflicts in Cyberspace (cont.)
• Online Bomb-Making instructions
Concerns on Cyberspace (cont.)
• Hate Speech
– exalts one group of people by denigrating another
– on the basis of race or religion
– the Council of Europe regard hate speech as a serious offense
and outlaw it on the Internet
– In America, free speech traditions protect offensive speech
"Even where the United States government finds the views expressed to
be misguided and repugnant-and surely those are appropriate words to
describe racism-our Constitution commands that we neither prohibit nor
regulate speech merely because we disapprove of the ideas expressed."
---Department of Justice
Concerns on Cyberspace (cont.)
Harmful Strangers
• According to a report from NRC, potentially harmful
strangers pose the greatest threat to children online
• Meeting a sexual predator through a chat room or e-mail
is far more dangerous than viewing inappropriate images
• A study found that one in five young peope aged 10-17
received an unwanted sexual solicitation on the Internet
• Some of them had been encouraged by people they met
on the Internet to run away from home.
Concerns on Cyberspace (cont.)
• Cyberpredators
– Use the Internet to disguise themselves and their intentions.
– Young users may put themselves in danger if they give away too
much information or plan to meet people they do not know.
– The Sexual Predator Punishment Act (1998)
– The act made it illegal to contact minors online for sexual
purposes or to transmit obscenity to them
Concerns on Cyberspace (cont.)
Invasion of privacy
• Children are giving away personal informations about themselves as
surfing the Web
• Young people leave their names and e-mail address in public place
like chat rooms
• In 1998, Federal Trade Commission surveyed 212 comercial
children's sites, 188 of the sites were building files of personal
informations. Less than 48 sites told visitors to ask for their parents'
permission before giving out informations.

Censorship on the Internet (cont.)
Technology Tools
• Filters: use one or more technologies to restrict
forbidden contents
– Use lists of Internet address to steer where you go online.
"white" lists vs. "black" lists
– Use keyword blocking.
eg. "sex", "satan"
– label recognition.
assign a rating, similar to movies', but not widely used
Censorship on the Internet (cont.)
Filters
• Over-block
– filters can block legal and useful informations
– why it happens?
• Rapidlly changing information on the internet
• Entire Web site is blocked because of a single page
• Different opinion may account for some over-blocking
• Under-block
– filters cannot block all objectionable material on the Internet
– Consumer Reports tested leading software filters in 2001, filters
allowed 20% of the objectionable sites through in their entirety.

Internet access in the U.S.

content but much useful and legal information, too.
• Children can be targets for cyberpredators and marketers.
