Radio is the radiation of electromagnetic energy through space. The biggest use of radio waves is to carry information, such as sound, by systematically changing some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Radio systems need a transmitter to change some property of the energy produced to impress a signal on it, for example using amplitude modulation, angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents
One reason is a perceived lack of quality and risk in the programming (to which more conservative elements respond that it is too risqué much of the time), an excessively high ratio of advertising to program time (especially on children's television), and a perceived failure to serve the local interest due to media consolidation. Commercial radio (in particular) is criticized for a perceived homogeneity in programming, covert politically motivated censorship of content, and a desire to cut costs at the expense of a station's identifiable personality. Politics is a major force in media criticism, with an ongoing debate (especially in the United States) as to what moral standards – if any – are to be applied to the airwaves.
