11920-Westhouse Electric Company established the world's first commercial radio station, KDKA
KDKA radio station , and was the world's first radio station officially broadcast every day, opened by Westinghouse Electric Company in Pittsburgh, USA on November 2, 1920. It is also the first radio station to obtain a federal experimental license. It quickly became history because of its series of breakthroughs, such as the first to report on sports competitions (a boxing match) and the first to broadcast live stage drama performances. The launch of KDKA marked the birth of a radio station. The first broadcast of
KDKA radio was on November 2, 1920, which was an amazing success. It aired the news of Warren Harding defeating James Cox as president. Pennial , Ohio and West Virginia have heard the broadcast.
At that time, all the staff at this station were Westinghouse employees and were all volunteers (Westhouse had KDKA radio since then). They start broadcasting every night at around 8:00 after their first airing. The broadcast content includes local news, inviting artists to perform live, reading stories to children before going to bed, etc.
The early working conditions of this radio station were also quite simple. Westinghouse retiree Charles Rucher's mother-in-law was a violinist on early radio broadcasts on KDKA radio and often took small buses to work. During the first live church broadcast, the station engineers wore choir robes and took their equipment to the local church. The first broadcast room of KDKA radio was in a cottage on the roof of the Westinghouse Building on the 8th floor. A tent was also set up on the roof for musicians to take a break, but it could not isolate the sounds that the actors practiced from time to time. Sometimes a moth flew into the actor's mouth, forcing him to stop singing. But this glitch does not seem to prevent the rapid increase in audience numbers. Because at that time, many radios were made by each company. People thought it was their machine that had malfunctioned and needed to wait for a while until the music started again.
Later, the station moved indoors and hired a full-time announcer, Harold Alin. His voice was pleasant and attracted many letters from female listeners. According to Michael Keith, professor of communications at Boston College and director of the Education Department of the Chicago Radio and Communications Museum, in two years, the United States has 500 radio stations and about 1.5 million radios, and every metropolitan in the United States has its own radio station.
Since the KDKA radio station in Pittsburgh, USA was officially launched in 1920, and has unfolded the world's broadcast history, with the advancement of science and the pursuit of higher quality of life by mankind, scientists have been constantly studying how to improve broadcast sound quality and improve broadcast service quality. Since the 1980s, due to the rapid development of digital technology, radio broadcast technology has entered the revolutionary era of digital broadcast technology.

November 2, 1981——The China Patent Document Museum is officially opened
Patent Document is a technical specification that specifically records new inventions. In countries and regions that implement the patent system, patent documents have developed into an important tool for rapidly popularizing and disseminating information on new inventions. It can enable people to promptly understand what new technologies and inventions have already existed in the world. Whether it is scientific research, production, management, or foreign trade units, they can benefit from reviewing patent documents. At that time, the Document Museum collected patent specifications from 15 countries and two international organizations, patent bulletins from more than 20 countries, and patent reference books, and nearly 8 million patent documents are available for readers to read. The documentary museum has a copying team that accepts the copying work entrusted by readers. You can also come to write to other places to handle copying work.
