Question

How Much Time for TV?

　　Once upon a time, there was no television. That wasn't because no one had tried to invent it. Scientists had worked on the idea starting in the late 1800's. Many years passed before television worked well.

　　In the 1940's, television caught on. It was a hit from the beginning. Soon the movie business, the restaurant business, and even the jukebox (大型唱機) business went down. Americans stayed home to watch television. How much watching do people do? The graph(圖表) below can help you decide.

　　This graph is called a pictograph. It shows the average number of hours a day that people have watched television in different years.

　　A pictograph uses pictures, or symbols, to show information. In the graph at the left, the symbol is a clock. Find the key at the bottom. The key tells you that each clock on the graph equals one hour of television watching. Half a clock equals one-half hour of watching.

　　To read the graph, count the number of clocks in the row for each year. A row runs across, from side to side. Use the graph to answer the questions below.
