Radio

Early uses were maritime, for sending telegraphic messages using Morse code between ships and land. The earliest users included the Japanese Navy scouting the Russian fleet during the Battle of Tsushima in 1905. One of the most memorable uses of marine telegraphy was during the sinking of the RMS Titanic in 1912, including communications between operators on the sinking ship and nearby vessels, and communications to shore stations listing the survivors.
Radio was used to pass on orders and communications between armies and navies on both sides in World War I; Germany used radio communications for diplomatic messages once its submarine cables were cut by the British. The United States passed on President Woodrow Wilson's Fourteen Points to Germany via radio during the war. Broadcasting began from San Jose in 1909[4], and became feasible in the 1920s, with the widespread introduction of radio receivers, particularly in Europe and the United States. Besides broadcasting, point-to-point broadcasting, including telephone messages and relays of radio programs, became widespread in the 1920s and 1930s. Another use of radio in the pre-war years was the development of detecting and locating aircraft and ships by the use of radar (RAdio Detection And Ranging).
Today, radio takes many forms, including wireless networks, mobile communications of all types, as well as radio broadcasting. Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment. Radio was unique among dramatic presentation that it used only sound. For more, see radio programming.

News

News is any new information or information on current events which is relayed by print, broadcast, Internet, or word of mouth to a third party or mass audience. The reporting and investigation of news falls within the profession of journalism. News is often reported by a variety of sources, such as newspapers, television, and radio programs, wire services, and web sites. News reporting is a type of journalism, typically written or broadcast in news style. Most news is investigated and presented by journalists and can be distributed to various outlets via news agencies.
There are many categories of news. The weather is typically presented by a certified meteorologist or, on smaller stations, a less-trained "weatherman" and is considered news. Other news categories are: sports, fashion, society, entertainment, business, cartoon strips, features, lottery numbers, lives of celebrities, advertising, and more. Until the 1970s, when women's lib issues came to the forefront, most newspapers had a "Women's" section devoted entirely to fashion and society news. Papers even printed "cheesecake" feature photos of attractive young women in bikinis, often transmitted by the AP or UPI wire services, illustrating various news events or feature ideas.

Collateral damage

Collateral damage is a military euphemism that was made popular at the time of Vietnam War (Army Technology). The euphemism has now been in use so long that it is an accepted term within military forces, meaning "unintentional damage or incidental damage affecting facilities, equipment or personnel, happening as a result of military actions directed against targeted enemy forces or facilities. Such damage can occur to friendly, neutral, and even enemy forces."
Etymologically, the expression "collateral damage" probably was originally used as military doublespeak rather than a euphemism, as the adjective "collateral" doesn't seem to have been used as a synonym for "unintentional" or "accidental" earlier. However, "collateral" may also sometimes mean "additional but subordinate," i.e. "secondary", and that specific meaning of a rather obscure word in the English language seems to have been picked up and broadened by the military in the expression "collateral damage."
