听力原文： With the introduction of the radio, newspaper publishers wondered how broadcasting would affect them. Many feared that radio as a quick and easy means of keeping people informed would displace the newspaper industry altogether. Others hoped that the brief newscast heard on the air would stimulate listeners' interests in the story so they would buy the paper to get more information. This second idea turned out to be closer to the truth. Radio & print were not substitutes for each other but actually supported each other. You see the relationship between different media is not al ways one of displacement but can be one of reinforcement. However, this is not always the case. Take television & motion pictures for example. With the popularization of T.V, the motion picture industry suffered greatly. Movie attendance dropped when audience members chose to stay at home and be entertained. Likewise, when a football game was shown on the air, the stands were often empty because fans chose to watch the game at home. (33)
