Not many years ago, families used to have one telephone and one TV
in the living room, and there was no such thing as a home computer.
Nowadays, all those items can be found in most teenagers’ bedrooms.
Behind closed doors, teens can have private conversations, and they can
turn the TV on to any channel they like. If they are curious, they will use
the Internet to explore places they never imagined existed, get a lot of
information, and talk to people far away. Having this equipment in their
own rooms means an increase in privacy for the kids.
