Television network in the context of Broadcast programming

Terrestrial television, or over-the-air television (OTA) is a type of television broadcasting in which the content is transmitted via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna. The term terrestrial is more common in Europe and Latin America, while in Canada and the United States it is called over-the-air or simply broadcast. This type of TV broadcast is distinguished from newer technologies, such as satellite television (direct broadcast satellite or DBS television), in which the signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and UHF bands. Since radio waves in these bands travel by line of sight, reception is generally limited by the visual horizon to distances of 64–97 kilometres (40–60 miles), although under better conditions and with tropospheric ducting, signals can sometimes be received hundreds of kilometers distant.

Terrestrial television was the first technology used for television broadcasting. The BBC began broadcasting in 1929 and by 1930 many radio stations had a regular schedule of experimental television programmes. However, these early experimental systems had insufficient picture quality to attract the public, due to their mechanical scan technology, and television did not become widespread until after World War II with the advent of electronic scan television technology. The television broadcasting business followed the model of radio networks, with local television stations in cities and towns affiliated with television networks, either commercial (in the US) or government-controlled (in Europe), which provided content. Television broadcasts were in greyscale (called black and white) until the transition to color television in the 1960s.

A television film (also known as television movie, telefilm, telemovie, made-for-TV film/movie, or TV film/movie) is a film with a running time similar to a feature film that is produced and originally distributed by or to a terrestrial or cable television network. It is in contrast to theatrical films first shown in movie theaters, direct-to-video films released only in home video formats, and films released on or produced for streaming platforms.

In certain cases, a television film may also be shown, and referred to, as a miniseries, which typically indicates that it has been divided into multiple parts or a series that contains a predetermined, limited number of episodes.

A global network is any communication network that spans the entire Earth. The term, as used in this article, refers in a more restricted way to bidirectional communication networks based on technology. Early networks such as international mail and unidirectional communication networks, such as radio and television, are described elsewhere.

The first global network was established using electrical telegraphy and global span was achieved in 1899. The telephony network was the second to achieve global status, in the 1950s. More recently, interconnected IP networks (principally the Internet, with estimated 2.5 billion users worldwide in 2014), and the GSM mobile communication network (with over 6 billion worldwide users in 2014) form the largest global networks of all.

Michael Dammann Eisner (/ˈaɪznər/ EYEZ-nər; born March 7, 1942) is an American businessman and media proprietor who served as chairman and chief executive officer (CEO) of the Walt Disney Company from September 1984 to September 2005. Prior to Disney, Eisner was president of rival film studio Paramount Pictures from 1976 to 1984, and had brief stints at the major television networks NBC, CBS, and ABC.

Eisner's 21-year stint at Disney saw the revitalization of the company's poorly performing animation studios with successful films such as The Little Mermaid (1989), Beauty and the Beast (1991), Aladdin (1992), and The Lion King (1994), a period known as the Disney Renaissance. Eisner additionally broadened the company's media portfolio by leading the acquisitions of ABC, most of ESPN and The Muppets franchise. Eisner also led major investments and expansion of the company's theme parks both domestically and globally, including the openings of Disney-MGM Studios (now Disney's Hollywood Studios) in 1989, Euro Disney (now Disneyland Paris) in 1992, Disney's Animal Kingdom in 1998, Disney's California Adventure Park and Tokyo DisneySea in 2001, Walt Disney Studios Park in 2002 and Hong Kong Disneyland in 2005.

In broadcasting, a flagship (also known as a flagship station or key station) is the broadcast station which originates a television network, or a particular radio or television program that plays a key role in the branding of and consumer loyalty to a network or station. This includes both direct network feeds and broadcast syndication, but generally not backhauls. Not all networks or shows have a flagship station, as some originate from a dedicated radio or television studio.

The term derives from the naval custom where the commanding officer of a group of naval ships would fly a distinguishing flag. In common parlance, "flagship" is now used to mean the most important or leading member of a group, hence its various uses in broadcasting. The term flagship station is primarily used in TV and radio in the United States, Canada, and the Philippines (though it is seldomly used), while the term key station (キー局, kī kyoku) is primarily used in TV in Japan (and formerly in the United States).

TLC is an American premium multinational cable and satellite television network owned by the Networks division of Warner Bros. Discovery. First established in 1980 as The Learning Channel, it initially focused on educational and instructional programming. By the late 1990s, after an acquisition by Discovery, Inc. earlier in the decade, the network began to pivot towards reality television programming—predominantly focusing on programming involving lifestyles and personal stories—to the point that the previous name with "The Learning Channel" spelled out was phased out in favor of its initialism.

As of November 2023, with its programming primarily dedicated to the nine-series 90 Day Fiancé universe, comprising 31% of the shows carried by the channel, TLC is available to approximately 71,000,000 pay television households in the United States—down from its 2011 peak of 100,000,000 households.

Breakfast television (Europe and Australia) or morning show (Canada and the United States) is a type of news or infotainment television programme that broadcasts live in the morning (typically scheduled between 5:00 and 10:00 a.m., or if it is a local programme, as early as 4:00 a.m.). Often presented by a small team of hosts, these programmes are typically marketed towards the combined demography of people getting ready for work and school and stay-at-home adults and parents.

The first – and longest-running – national breakfast/morning show on television is Today, which set the tone for the genre and premiered on 14 January 1952 on NBC in the United States. For the next 70 years, Today was the number one morning program in the ratings for the vast majority of its run and since its start, many other television stations and television networks around the world have followed NBC's lead, copying that program's successful format.

The production control room (PCR) or studio control room (SCR) is the area in a television studio in which the configuration of the outgoing program takes place.

The production control room is occasionally also called an SCR, or, in British English, a gallery – the latter name comes from the original placement of the director on an ornately carved bridge spanning the BBC's first television studio at Alexandra Palace which was once referred to as like a minstrels' gallery. Master control is the technical hub of a broadcast operation common among most over-the-air television stations and television networks. Master control is distinct from a PCR in television studios where the activities such as switching from camera to camera are coordinated. A transmission control room (TCR) is usually smaller in size and is a scaled-down version of centralcasting.

Citytv (sometimes shortened to City, which was the network's official branding from 2012 to 2018) is a Canadian television network owned by the Rogers Sports & Media subsidiary of Rogers Communications. The network consists of six owned-and-operated (O&O) television stations located in the metropolitan areas of Toronto, Montreal, Winnipeg, Calgary, Edmonton, and Vancouver, a cable-only service that serves the province of Saskatchewan, and two independently owned affiliates serving smaller cities in British Columbia. There is also one station using the brand name serving Bogotá, Colombia.

The Citytv brand name originates from its flagship station, CITY-TV in Toronto, a station that went on the air in September 28, 1972, in the former Electric Circus nightclub, and which became known for an intensely local format based on newscasts aimed at younger viewers, nightly movies, and music and cultural programming. The Citytv brand first expanded with then-parent company CHUM Limited's acquisition of former Global owned-and-operated station CKVU-TV in Vancouver, followed by its purchase of Craig Media's stations and the re-branding of its A-Channel system in Central Canada as Citytv in August 2005. CHUM Limited was acquired by CTVglobemedia (now Bell Media) in 2007; to comply with Canadian Radio-television and Telecommunications Commission (CRTC) ownership limits, the Citytv stations were sold to Rogers. The network grew through further affiliations with three Jim Pattison Group-owned stations, along with Rogers's acquisition of the cable-only Saskatchewan Communications Network and Montreal's CJNT-DT. At one point, Citytv also existed in Barcelona and San Juan, Puerto Rico.

Cable news channels are television networks devoted to television news broadcasts, with the name deriving from the proliferation of such networks during the 1980s with the advent of cable television.
