Christian radio refers to Christian media radio formats that focus on Christian religious broadcasting or various forms of Christian music. Many such formats and programs include contemporary Christian music, gospel music, sermons, radio dramas, as well as news and talk shows covering popular culture, economics, and political topics from a Christian perspective.,
Brokered programming is a significant portion of most U.S. Christian radio stations' revenue, with stations regularly selling blocks of airtime to evangelists seeking an audience. Another revenue stream is solicitation of donations, either to the evangelists who buy the air time or to the stations or their owners themselves. In order to further encourage donations, certain evangelists may emphasize the prosperity gospel, in which they preach that tithing and donations to the ministry will result in financial blessings from God. Others may have special days of the year dedicated to fundraising, similar to many NPR stations. Although the solicitation of donations and the sale of airtime may resemble a commercial enterprise, such actions do not necessarily constitute a call to action, and thus this does not forbid them from airing on noncommercial licensed stations in the U.S. A minority of stations, typically music stations, use the traditional model for music radio and allow traditional commercial advertising.
Numerous religious broadcasters own many of their own stations. In the U.S., religious radio stations are exempt from certain rules requiring radio stations to have some local operations, which allows them to have massive networks of transmitters covering far larger areas than a radio station would otherwise be allowed and may not face the same restrictions on the number of signals a broadcaster can own within one geographic area.
Most Christian radio stations transmit a mixture of Christian music and Christian talk and teaching.
Christian music radio outlets mirror commercial radio in many ways, and music in a variety of different genres is available.
