TV sets are the product of modern technology and one of the most updated electronic products. Nowadays, the TV sets that sit in the homes of the people are unknown to generations. However, the TV set as the new technology product for the first time in the World Expo is not far away. It was in 1939 that the US government held the World Expo in New York to commemorate the founding father of Washington in 150 years. The theme of this World Expo is "Tomorrow's World and Construction." Despite the end of World War I and the economic depression, 45 million people have come to participate in the exhibition and visit from 64 countries and regions. The TV sets, tape recorders, nylons, plastic products and other products on display at the meeting made people feel refreshed, which ignited people's hopes for a new life. The old ones have passed, and the world of tomorrow will be even better.
