In the old days, a radio format was the way the station's program director arranged the sequence of programming elements to make up the day's schedule. After the "golden age" of radio, when most programming was provided by the big networks, individual radio stations developed local disc-jockey shows interrupted every half hour with news. Over the years, formats have evolved to the point where radio programming is carefully designed to reach a specifically defined segment or "niche" of the population, based on such demographic criteria as age, income, ethnic background, etc. A format may refer to the overall programming (i.e. adult standards, news, etc.) or the particular arrangement of programming elements within a given hour.
