Radio Ukraine International is the official international broadcasting station of Ukraine. RUI acquaints foreign listeners with all diversity of political and social-economic life in Ukraine and helps Ukrainians abroad keep in touch with home. Radio Ukraine International broadcasts in four languages: Ukrainian, English, German, Romanian. 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 of propaganda, 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
