There are thousands of magazines published in the world to meet the needs of different readers . But only a few of them are influential world-wide .   You have hit the point . It's really hard for a magazine to be well known to people of various ages and educational backgrounds .   But I think Digest is supposed to be the top one . Its subscribers or buyers are from all social classes , perhaps , a majority of them from the educated group . It's quite strange that the readers love it after reading it .   To my mind , the success of Digest is in the clever selection of its articles in each issue .
