The first regular television broadcasts started in 1937. Broadcasts can be classified as ''recorded'' or ''live''. The former allows correcting errors, and removing superfluous or undesired material, rearranging it, applying [[slow-motion]] and repetitions, and other techniques to enhance the program. However, some live events like [[sports television]] can include some of the aspects including slow-motion clips of important goals/hits, etc., in between the [[live television]] telecast. American radio-network broadcasters habitually forbade prerecorded broadcasts in the 1930s and 1940s, requiring radio programs played for the Eastern and Central [[time zone]]s to be repeated three hours later for the Pacific time zone (See: [[Effects of time on North American broadcasting]]). This restriction was dropped for special occasions, as in the case of the German [[dirigible]] airship ''[[Hindenburg disaster|Hindenburg]]'' disaster at [[Lakehurst, New Jersey]], in 1937. During [[World War II]], prerecorded broadcasts from war correspondents were allowed on U.S. radio. In addition, American radio programs were recorded for playback by [[Armed Forces Radio]] [[radio station]]s around the world.

A disadvantage of recording first is that the public may learn the outcome of an event before the recording is broadcast, which may be a [[spoiler (media)|spoiler]]. Prerecording may be used to prevent [[announcer]]s from deviating from an officially approved [[screenplay|script]] during a [[live radio]] broadcast, as occurred with [[propaganda]] broadcasts from Germany in the 1940s and with [[Voice of Russia|Radio Moscow]] in the 1980s. Many events are advertised as being live, although they are often recorded live (sometimes called "[[live television|live]]-to-[[video tape|tape]]"). This is particularly true of performances of musical artists on radio when they visit for an in-studio [[concert]] performance. Similar situations have occurred in [[television production]] ("''[[The Cosby Show]]'' is recorded in front of a [[live television]] studio [[audience]]") and [[news broadcasting]].

A broadcast may be distributed through several physical means. If coming directly from the [[radio studio]] at a single station or [[television station]], it is sent through the [[studio/transmitter link]] to the [[transmitter]] and hence from the [[television antenna]] located on the [[radio masts and towers]] out to the world. Programming may also come through a [[communications satellite]], played either live or recorded for later transmission. Networks of stations may [[simulcast]] the same programming at the same time, originally via [[microwave]] link, now usually by satellite. Distribution to stations or networks may also be through physical media, such as [[magnetic tape]], [[compact disc]] (CD), [[DVD]], and sometimes other formats. Usually these are included in another broadcast, such as when [[electronic news gathering]] (ENG) returns a story to the station for inclusion on a [[news program]]me.

The final leg of broadcast distribution is how the signal gets to the listener or viewer. It may come over the air as with a [[radio station]] or [[television station]] to an [[antenna (radio)|antenna]] and [[radio receiver]], or may come through [[cable television]]<ref>{{cite web|url=https://www.diwaxx.ru/|title=Информационно – развлекательный портал – DIWAXX.RU – мобильная связь, безопасность ПК и сетей, компьютеры и программы, общение, железо, секреты Windows, web-дизайн, раскрутка и оптимизация сайта, партнерские программы|website=Diwaxx.ru|access-date=11 November 2017|archive-date=3 November 2017|archive-url=https://web.archive.org/web/20171103065154/http://www.diwaxx.ru/|url-status=live}}</ref> or [[cable radio]] (or [[wireless cable]]) via the station or directly from a network. The [[Internet]] may also bring either [[internet radio]] or [[streaming media]] television to the recipient, especially with [[multicast]]ing allowing the signal and [[Bandwidth (computing)|bandwidth]] to be shared. The term ''[[broadcast network]]'' is often used to distinguish networks that broadcast over-the-air television signals that can be received using a [[tuner (television)|tuner]] inside a [[television set]] with a [[television antenna]] from so-called networks that are broadcast only via [[cable television]] ([[cablecast]]) or [[satellite television]] that uses a [[dish antenna]]. The term ''[[broadcast television]]'' can refer to the [[television program]]s of such networks.
