Newspapers are not nearly as popular today as they were in the past.There are not very many people who seriously read a newspaper every day. Most people read only the sports pages,the advice or the gossip columns,the comics, and perhaps the classified advertisements.Most people don’t take the time to read the real news. Newspapers attempt to catch the reader’s interest with pictures and exciting headlines. These techniques are used on the front page because it is the first thing you see when you pick up the paper.The first page attracts attention and encourages the reader to look through the rest of the paper. This is why editors always look for a good first page story and headline to make them stop and look.If the headline is horrible enough or frightening enough or wild enough,perhaps they will go on to read the front page.However,they may just read the headlines,but that is all,then they turn to the sports page,or comics,or advertisements. It seems that people do not want the news from a newspaper anymore. They say they get the news on the television now.

More people watch television news because it is easier and more interesting than reading a newspaper.What about you? Do you read news from a newspaper? Do you think it is easier to get
