Radio is the use of electromagnetic waves for communication. This is used both for broadcast (one-to-many) and point-to-point (one-to-one) communication of voice, music, code, and other data. Transmission of video by radio waves is known as television. Transmissions can be analog or digital. These days, broadcasts are often simulcast on the Internet as well.
