The article presents a discussion on radio and television broadcasting for cars. In-car entertainment services are taking a shift from amplitude-modulation and frequency-modulation broadcasting to live radio broadcasting via terrestrial and satellite networks. This trend is reminiscent of the time decades ago when cable television started to make inroads into people's homes. With the success of satellite radio in the U.S. and the Digital Audio Broadcast system in Great Britain, there is now an enormous investment from all stakeholders to produce standards, secure spectrum, prepare content, investigate business models, and launch equipment needed to provide live television broadcasting to automobiles. Third-generation networks promise bandwidth for live television broadcasting. But critics question what happens if millions of people tune in to see the same show at the same time, making it difficult to scale a point-to-point network. The technology for the reception of television programs in cars consists of an analog front end with a tuner.
