The Oregonian(俄勒冈报) is the daily newspaper for the state of Oregon where the Hagens live. Since it is published in the largest city, which is Portland, most of the readers live within 50 miles of Portland.

From Monday to Saturday, the paper has about 75 pages, of which 20 pages are advertisements. It normally has 5 sections which are called Nation, Sports, Metro(大都会), Living and Business.

Nation is national news mostly with some international news about earthquakes, floods, and tensions(紧张)around the world. Sports cover the professional sports in season, college sports, and high school sports. Metro is local news of the city of Portland which includes political stories, crimes, and good neighbor articles. Living is the section with television programs, movies, comics, music, stories about pets, and advice. Business has listing of more than 10,000 stocks and a regular report about the stock market and business news. The advertising section includes apartments and houses, employment opportunities and items to buy, especially cars and trucks.

On Sunday, the paper is very large weighing more than two kilos. There are additional sections called Art, Books, International, and Travel. Since this is the day most Americans do not work, they have more time for reading. Each of the daily sections is longer so the newspaper is twice the size of the daily sections. However, the advertisements are nearly as many pages as the news on Sunday so the entire paper is more than four times larger than the daily paper.

Some companies print their own advertisements and pay to put them in The Oregonian. These include grocery(杂货) stores, clothing stores, car agencies(代理处), camera and video equipment stores, toy stores, and computer stores. All of the companies feel that the best way to advertise is to put a beautiful color advertisement in every Sunday.
