Broadcasting is the distribution of audio or video content to a wide audience through radio, television, or the internet. It involves the transmission of signals from a central source to multiple receivers, allowing for mass communication and the dissemination of information, news, entertainment, and other forms of content. Broadcasting research focuses on improving transmission technologies, audience measurement, content creation and delivery, regulatory policies, and the impact of broadcasting on society and culture. Research in this area is essential for understanding how broadcasting influences public opinion, shapes media consumption habits, and impacts society as a whole.
