Weekends are important for us. We can relax ourselves. Do you know what Americans in the early twentieth century (1900~1925) did on weekends? What do you do on weekends now? In the early twentieth century, people spent lots of time at home on weekends. Then, new inventions changed the weekends.

*People used electric streetcars to travel in the cities. On weekends, they rode the streetcars to the parks. Young people like roller coasters.

* The first movie lasted only one minute. In the 1920s, movie theaters sold millions of tickets each week! In 1927, movies finally had sound. Sometimes people stayed at home and listened to another new invention —the radio.

* People in cities worked indoors during the weekdays, so they wanted to be outdoors on weekends. Bicycling became a popular activity.

* Now there are more inventions in our life. People have more time and money, too. So they have many ways to spend their weekends.

* People travel by their own cars. Or they can visit big parks like Disney World and ride modern roller coasters and go higher and faster than ever before. *

They can choose from lots of different movie theatres. Or they can watch videos at home.
