Thirty-one percent of you read or listen to the news every day, but only sixteen percent like watching current affairs shows. Youre more interested in national news than international news, but nearly eighty-five percent of our readers watch newS flashes about important events in the world. 4 So, is there any room for newspapers in today's world? Twenty-three percent of you said yes, but more than half (fifty-one percent) said you could live without them. Jake and Lisa explain their views: Jake Moreno (16) Tve never bought anewspaper. I usually find out about the news through a social networking site. That's how I heard about the tsunami in Japan. One of my friends added a link to a news flash. News websites are good too, becauseyou can listen to podcasts and watch videos.
