News broadcasting

News broadcasting is the medium of broadcasting of various news events and other information via television, radio or internet in the field of broadcast journalism. The content is usually either produced locally in a radio studio or television studio newsroom, or by a broadcast network. It may also include additional material such as sports coverage, weather forecasts, traffic reports, commentary and other material that the broadcaster feels is relevant to their audience.

Television news

Television news refers to disseminating current events via the medium of television. A "news bulletin" or a "newscast" are television programs lasting from seconds to hours that provide updates on world, national, regional or local news events. There are numerous providers of broadcast news content such as NBC, CNN or Fox News, as well as numerous programs that regularly provide this content such as NBC Nightly News. Television news is very image-based, showing video footage of many of the events that are reported; still photography is also used in reporting news stories, although not as much in recent years as in the early days of broadcast television. Television channels may provide news bulletins as part of a regularly scheduled news program. Less often, television shows may be interrupted or replaced by breaking news reports ("news flashes") to provide news updates on events of great importance.

Canada (ⁱ/ˈkænədə/; French: [ka.na.da]) is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres (3.85 million square miles), making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains; about four-fifths of the country's population of 35 million people live near the southern border. The majority of Canada has a cold or severely cold winter climate, but southerly areas are warm in summer.

The land now called Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the 15th century, British and French colonies were established on the Atlantic coast, with the first establishment of a region called "Canada" occurring in 1537. As a consequence of various conflicts, the United Kingdom gained and lost territories within British North America until left, in the late 18th century, with what mostly geographically comprises Canada today. Pursuant to the British North America Act, on July 1, 1867, the colonies of Canada, New Brunswick, and Nova Scotia joined to form the autonomous federal Dominion of Canada. This began an accretion of provinces and territories to the self-governing Dominion to the present ten provinces and three territories forming modern Canada. In 1931, Canada achieved near total independence from the United Kingdom with the Statute of Westminster 1931, and full sovereignty was attained when the Canada Act 1982 removed the last remaining ties of legal dependence on the British parliament.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Canadian Broadcasting Corporation

The Canadian Broadcasting Corporation (French: Société Radio-Canada), officially branded as CBC/Radio-Canada, is a Canadian crown corporation that serves as the national public radio and television broadcaster. The English- and French-language services units of the corporation are commonly known as CBC and Radio-Canada respectively, and both short-form names are also commonly used in the applicable language to refer to the corporation as a whole.

Although some local stations in Canada predate CBC's founding, CBC is the oldest existing broadcasting network in Canada, first established in its present form on November 2, 1936. Radio services include CBC Radio One, CBC Radio 2, Ici Radio-Canada Première, Ici Musique and the international radio service Radio Canada International. Television operations include CBC Television, Ici Radio-Canada Télé, CBC News Network, Ici RDI, Ici Explora, Ici ARTV (part ownership), and documentary. The CBC operates services for the Canadian Arctic under the names CBC North and Radio-Canada Nord. The CBC also operates digital services including CBC.ca / Ici.Radio-Canada.ca, CBC Radio 3, CBC Music / ICI.mu and Ici.TOU.TV, and owns 20.2% of satellite radio broadcaster Sirius XM Canada, which carries several CBC-produced audio channels.
