Deregulation has been motivated by increased profit margins, reduced risk, and maintaining a competitive edge. However, some radio station owners have argued that deregulation has made it harder to sell their stations because audience and revenue are down by half. 
Radio deregulation is the process of removing or reducing regulations that apply to the commercial broadcast industry. The Federal Communications Commission (FCC) officially began the process in 1981 with a broadcast deregulation order that changed or removed many regulations. 
The deregulation of radio broadcasting has included:
Non-entertainment program regulation
The FCC removed guidelines that specified how much informational programming stations needed to have their license renewed. Instead, stations are now required to offer programming that responds to public issues.
Commercials
The FCC removed guidelines on the maximum amount of commercial time stations can have on the air. National and local restrictions on ownership
The 1996 Telecommunications Act removed these restrictions, which specified how many stations one company could own in a market. 
Lessons from FCC Regulation of Radio Broadcasting" the Deregulation of Radio consisted of: Non entertainment program regulation. The FCC eliminated "guidelines" indicating how much informational programming each station should carry to have its license renewed, replacing it with "a generalized obligation for commercial radio stations to offer programming responsive to public issues." Ascertainment. Elimination of formal documentation of "community needs". Commercials. Abolition of FCC guidelines on maximum commercial time allowed on radio stations. Program logs.
Since deregulation, more than a third of all US radio stations have been bought and sold. For example, four corporations control the music and news delivered to more than half of the radio audience.
