Television broadcast refers to the transmission of audio and visual content to a wide audience through electromagnetic waves. This process allows viewers to receive programs, such as news, entertainment, and educational shows, on their television sets. The content is typically produced by television networks and can be delivered via various methods, including terrestrial, satellite, and cable systems. The broadcast signal is sent from a transmitter to a receiver, which decodes the information for display. Television broadcasts can be live or pre-recorded, and they often include advertisements to generate revenue for the networks. With the rise of digital technology, many broadcasts are now available in high definition, enhancing the viewing experience.
