International Day of Broadcasting – December 10
International Broadcasting Day has been celebrated every year, on December 10.International broadcasting is broadcasting that is deliberately aimed at a foreign, rather than a domestic, audience. It usually is broadcast by means of longwave,mediumwave, or shortwave radio, but in recent years has also used direct satellite broadcasting and the internet as means of reaching audiences.
Although radio and television programs do travel outside national borders, in many cases reception by foreigners is accidental. However, for purposes ofpropaganda, transmitting religious beliefs, keeping in touch with colonies or expatriates, education, improving trade, increasing national prestige, or promoting tourism and goodwill, broadcasting services have operated external services since the 1920s.
