Due to the FCC's limits on station ownership at the time (which prevented the common ownership of multiple radio stations), local marketing agreements in radio, in which a smaller station would sell its entire airtime to a third-party in time-buy, were widespread between the 1970s and early 1990s. These alliances gave larger broadcasters a way to expand their reach, and smaller broadcasters a means of obtaining a stable stream of revenue. In 1992, the FCC began allowing broadcasting companies to own multiple radio stations in a single market. Following these changes, local marketing agreements largely fell out of favor for radio, as it was now possible for broadcasters to simply buy another station outright rather than lease it – consequentially triggering a wave of mass consolidation in the radio industry. However, broadcasters still used local marketing agreements to help transition acquired stations to their new owners.
