Many adherents to the youth counterculture of the s came from affluent, middle-class families, and their tastes came to define a new era of consumer culture.

The goals and market potential of both the high-fidelity lovers and the youth counterculture created an atmosphere on the FM dial that had never before occurred.

Between the years and , the number of households capable of receiving FM transmissions grew from about 6. Before this regulation, many AM stations had other stations on the FM spectrum that simply duplicated the AM programming. The nonduplication rule forced FM stations to create their own fresh programming, opening up the spectrum for established networks to develop new stations.

The late s saw new disc jockeys taking greater liberties with established practices; these liberties included playing several songs in a row before going to a commercial break or airing album tracks that exceeded 10 minutes in length. University stations and other nonprofit ventures to which the FCC had given frequencies during the late s popularized this format, and, in time, commercial stations tried to duplicate their success by playing fewer commercials and by allowing their disc jockeys to have a say in their playlists.

Although this made for popular listening formats, FM stations struggled to make the kinds of profits that the AM spectrum drew. In , FM radio accounted for one-third of all radio listening but only 14 percent of radio profits.

Large network stations and advertisers began to market heavily to the FM audience in an attempt to correct this imbalance. Stations began tightening their playlists and narrowing their formats to please advertisers and to generate greater revenues. By the end of the s, radio stations were beginning to play specific formats, and the progressive radio of the previous decade had become difficult to find. After the Golden Age of Radio came to an end, most listeners tuned in to radio stations to hear music.

The variety shows and talk-based programs that had sustained radio in early years could no longer draw enough listeners to make them a successful business proposition. One divergent path from this general trend, however, was the growth of public radio. Groups such as the Ford Foundation had funded public media sources during the early s.

When the foundation decided to withdraw its funding in the middle of the decade, the federal government stepped in with the Public Broadcasting Act of This act created the Corporation for Public Broadcasting CPB and charged it with generating funding for public television and radio outlets. In the mids, NPR attracted Washington-based journalists such as Cokie Roberts and Linda Wertheimer to its ranks, giving the coverage a more professional, hard-reporting edge.

However, in , public radio was pushed to the brink of financial collapse. A Prairie Home Companion , hosted by Garrison Keillor pictured here , is a long-standing public radio tradition that hearkens back to the early days of radio variety shows. Having weathered the financial storm intact, NPR continued its progression as a respected news provider. During the first Gulf War, NPR sent out correspondents for the first time to provide in-depth coverage of unfolding events.

Although some have accused NPR of presenting the news with a liberal bias, its listenership in was 28 percent conservative, 32 percent liberal, and 29 percent moderate. With more than 26 million weekly listeners and member stations in , NPR has become a leading radio news source. Public radio distributors such as Public Radio International PRI and local public radio stations such as WBEZ in Chicago have also created a number of cultural and entertainment programs, including quiz shows, cooking shows, and a host of local public forum programs.

This variety of popular public radio programming has shifted radio from a music-dominated medium to one that is again exploring its vast potential. During the early s, many radio stations suffered the effects of an economic recession. Some stations intiatied Local Marketing Agreements LMAs Agreements between radio stations and networks to share facilities and resources. LMAs led to consolidation in the industry as radio stations bought other stations to create new hubs for the same programming.

The Telecommunications Act of further increased consolidation The purchase of multiple radio stations by a single owner. As large corporations such as Clear Channel Communications bought up stations around the country, they reformatted stations that had once competed against one another so that each focused on a different format. Ultimately, although the industry consolidation of the s made radio profitable, it reduced local coverage and diversity of programming. Because stations around the country served as outlets for a single network, the radio landscape became more uniform and predictable.

Much as with chain restaurants and stores, some people enjoy this type of predictability, while others prefer a more localized, unique experience.

This was not always the case, however. Before the 19th century, wireless radio communication in everyday life was a thing of fantasy. Even after the development of the radio in the late s, it took many years before radios went mainstream and became a household fixture. The history of the radio is a fascinating one that changed how the world connected and communicated from distances both far and near.

While the radio enjoys a long and interesting history, its earliest beginnings are still quite controversial. There's some debate as to who actually invented the radio.
