Broadcast delay refers to a technique utilized primarily in broadcasting[1], where live material is held back for a brief period before being transmitted. This technique is commonly used to prevent the broadcast of undesirable content, such as profanity, or to align the timing of nationwide simultaneous broadcasts. The concept originated at the WKAP radio station in Pennsylvania, with the tape delay system gaining popularity in the US. Today, the technique is applied globally, often to compensate for different time zones. In professional sports, broadcast delay plays a crucial role in preventing cheating and ensuring fair play. However, with the advent of médias sociaux[2] and the increasing global availability of live events, traditional tape delays are becoming less prevalent. Despite this, broadcast delay continues to be a significant aspect of broadcasting, influencing scheduling decisions and content editing for regions without live coverage.

1. broadcasting. Broadcasting, a key aspect in the realm of communication, has a rich and diverse history. It began with the transmission of telegraph signals over airwaves using Morse code, evolving into wireless communication and commercial radio broadcasting for news and entertainment. Broadcasting methods have advanced over the years, from central high-powered towers transmitting electromagnetic waves to receivers, to the digital age of streaming services. This influential technology plays an essential role in disseminating information and entertainment, shaping society, culture, and communication. Broadcasting encompasses various methods like radio, television, and internet streaming, and different types of services, such as public, community, and commercial. Technological advances have transformed the industry, with the internet and mobile devices making broadcasting more accessible globally.
2. médias sociaux. Les médias sociaux sont un terme général qui englobe une variété d'outils et de plateformes numériques qui facilitent le partage d'informations et la création de communautés virtuelles. Issus des premiers systèmes comme PLATO et ARPANET, ils ont évolué vers des plateformes modernes comme Facebook et Twitter. Ces plateformes offrent des caractéristiques uniques qui les différencient des médias traditionnels, notamment la possibilité pour les utilisateurs de générer du contenu et de s'engager dans une communication dialogique. Elles accueillent plus de 100 millions d'utilisateurs dans le monde et offrent différentes formes de services, telles que des applications de messagerie et des plateformes de création de contenu collaboratif. L'utilisation des médias sociaux a des répercussions considérables sur les individus, la société et les entreprises, influençant tout, des pratiques de marketing aux processus politiques. Cependant, elle est également associée à des préoccupations éthiques, telles que la diffusion de fausses informations et la dépendance potentielle.

Au radio et télévision, broadcast delay is an intentional delay when broadcasting live material, technically referred to as a deferred live. Such a delay may be to prevent mistakes or unacceptable content from being broadcast. Longer delays lasting several hours can also be introduced so that the material is aired at a later scheduled time (such as the prime time hours) to maximize viewership. Tape delays lasting several hours can also be edited down to remove filler material or to trim a broadcast to the network's desired run time for a broadcast slot, but this is not always the case.

Many US radio talk shows use broadcast delay to avoid FCC penalties
