On March 17, 1958, China's first black-and-white television was born at the Tianjin Television Factory. It was named "Beijing Brand" and was known as "China's First Screen".

This TV is now displayed in the product showroom of Tianjin Communications and Broadcasting Company. It is the starting point of the history of television production in our country. Later, television gradually entered the homes of ordinary people.
