TV cameras broadcast an interview on live television. Broadcasting is the transmission of radio and television programmes via cables, ground-based transmitters, satellites and the internet. There are thousands of different TV channels around the world, broadcasting entertainment, news, information and sport. TV programmes are created at television stations. Some programmes, such as news and sports, are broadcast live, which means the viewers see action as it happens. Most programmes are recorded and broadcast at a later date.
Television programmes such as news, discussions and games shows are made in a large room at the TV station called a studio. Each programme has its own backgrounds and furniture called a set. Cameras and microphones send signals to the control room. Lighting comes from powerful lamps. The camera operator steers the camera while checking the picture in the viewfinder. The floor manager also works in the studio. He or she makes sure everything runs smoothly.
The word broadcasting was originally used to describe the planting of seeds by throwing them by hand over the soil. The term was first used by one of the first radio broadcasters, the American Charles Herrold (he gave regular broadcasts between 1912 and 1917), who was the son of a farmer.
