There was no rotation schedule to follow, and the only rules were those laid down by the FCC regarding profanity and station identification - everything else was up to the DJ. With no stylistic boundaries, programming was as diverse and unique as the personalities behind the mic. Freeform DJs shared a loose ideology, a sense of spontaneity, and a desire to expose lesser-known artists and songs. Some engaged in conversations with the listeners, drawing them into the development of the program, even entertaining live call-ins.
Many leaned a bit on the radical or liberal side of the spectrum; however, aside from occasional Vietnam-era sentiments, most hosts rarely were overtly political. Looking back through eyes filtered by today's commercial radio landscape, this concept was and still is revolutionary, especially when one considers that freeform exists in direct opposition to commercial radio’s stricter control over programming.
By the late ’60s, freeform programming was more common on FM bands in the larger markets, eventually becoming the medium and style of choice to tap into an ever-expanding youth culture. Sharing ideals such as diversity, freedom, and perhaps even a slight tinge of radicalism, freeform radio is easily thought of as a product of the ’60s.
