Like AOL for instance will take the sites you visit and get a profile on you and then sell that profile to companies so that they can send you advertisements. While this practice is a little unethical it is however completely legal. It is a lot like sites paying search engines to put their names at the top of the list when you search for stuff. These are issues that everyone needs to be aware of in the information age. Part of using technology is knowing the consequences of using technology and the dangers of using technology.
Some people become addicted to technology.
Weather it is playing games on the Internet or talking to people in chat rooms. People become addicted because they make up there own names and there own identity and if they grow tired of it they can just change it. A luxury not afforded to every day life. Some people even come to prefer this to the outside world and become introverted. It can become a person s whole world living inside these chat rooms.
