     For the final speaker here today, I would like to
share you some of the conclusions of our research.We
wanted to know that the Internet would become the most
popular source of news for people.They have found that
although the Internet has become increasing popular, 
the number of people which get news from the Internet
compares to the radio or television is still small.While
the Internet is the popular tool, it is still not as easily accessible
as newspapers, television and the radio is, and due to
the amount of uncontrolled information on the Internet,
people do not always trust the news they find it online.
