[originaltext] Mr. Foster started his publishing business with only one maga

Mr. Foster started his publishing business with only one magazine. It was called World News. Mostly it had summaries of important week events from around the world. But it always included one or two stories about interesting people. Mr. Foster put these in because he believed all people like to read about other people. Several years ago, Mr. Foster started two magazines. One was called Enterprise. It is for business people. And the other was called Action, for sports fans, like World News, they always have two or three stories about interesting people. Five years ago, Mr. Foster got another idea for a magazine. He wanted this one to have even more stories about people than the others and to have more photographs. This one was named Faces and Places. From the very beginning, it was a big success.
