Radio networkThere are two types of radio network currently in use around the world: the one-to-many (simplex communication) broadcast network commonly used for public information and mass-media entertainment, and the two-way radio (duplex communication) type used more commonly for public safety and public services such as police, fire, taxicabs, and delivery services. Cell phones are able to send and receive simultaneously by using two different frequencies at the same time. Many of the same components and much of the same basic technology applies to all three.

PBS is a publicly funded nonprofit organization and the most prominent provider of educational programs to public television stations in the United States, distributing shows such as Frontline, Nova, PBS NewsHour, Arthur, Sesame Street, and This Old House.

InfomercialAn infomercial is a form of television commercial that resembles regular TV programming yet is intended to promote or sell a product, service or idea. It generally includes a toll-free telephone number or website. Most often used as a form of direct response television (DRTV), they are often program-length commercials (long-form infomercials), and are typically 28:30 or 58:30 minutes in length. Infomercials are also known as paid programming (or teleshopping in Europe).
Television broadcasterA television broadcaster or television network or is a telecommunications network for distribution of television content, where a central operation provides programming to many television stations, pay television providers or, in the United States, multichannel video programming distributors. Until the mid-1980s, broadcast programming on television in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks such as the BBC, CBS, NBC or ABC in the USA and in Australia evolved from earlier radio networks.
BBCThe British Broadcasting Corporation (BBC) is a British public service broadcaster headquartered at the Broadcasting House in London, originally established in 1922 as the British Broadcasting Company and evolved into its current state with its current name on New Year's Day 1927. The oldest and largest local and global broadcaster by stature and by number of employees, it employs over 21,000 staff in total, of whom approximately 17,900 are in public-sector broadcasting.
The CWThe CW Television Network (commonly referred to as just The CW) is an American English-language commercial broadcast television network that is controlled – through The CW Network, LLC – by Nexstar Media Group, with a 75% ownership interest. The network's name is derived from the first letters of the names of its two founding co-owners CBS Corporation and Warner Bros. (the latter was owned by Time Warner, later AT&T's WarnerMedia). Nexstar closed its acquisition of a controlling interest in The CW on October 3, 2022, with Paramount Global and Warner Bros.
Satellite televisionSatellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner.
TelemundoTelemundo (English pronunciation: , teleˈmundo; formerly NetSpan) is an American Spanish-language terrestrial television network owned by NBCUniversal Telemundo Enterprises, a division of NBCUniversal, which in turn is a wholly owned subsidiary of Comcast. It provides content nationally with programming syndicated worldwide to more than 100 countries in over 35 languages. The network was founded in 1984 as NetSpan before being renamed Telemundo in 1987 after the branding used on WKAQ-TV, its owned-and-operated station in San Juan, Puerto Rico.
Paramount+Paramount+ is an American subscription video on-demand over-the-top streaming service owned by Paramount Global.

Specialty channelA specialty channel (also known in the United States as a cable channel or cable network) can be a commercial broadcasting or non-commercial television channel which consists of television programming focused on a single genre, subject or targeted television market at a specific demographic. The number of specialty channels has greatly increased during the 1990s and 2000s while the previously common model of countries having just a few (national) TV stations addressing all interest groups and demographics became increasingly outmoded, as it already had been for some time in several countries.
