Since the late 1980s, FCC regulations have replaced the "seven dirty words" criteria with the "community standards" language of Miller v. California. This change has affected college radio stations as it has their commercial and public radio counterparts. Many college stations cannot afford fines  which would make it impossible for them to continue operations. Therefore, experimental programs have either been curtailed or relegated to late-night "safe harbor" periods. In addition, there have been FCC investigations of rap and rock music played on college stations on the basis of code words for "sexually deviate" behavior. The present FCC policy, as interpreted by at least some college administrators, has caused self-censorship of potentially "offensive" music or other presentations on college radio stations.

As stated above, private colleges have greater latitude in what they consider  protected speech and expression. This is especially relevant to the next two cases listed.
