The introduction of all-night radio broadcasts in the mid-1960's coincides with the popularization of college attendance, for which rapidly growing numbers of young aspiring students will sit at their desks late into the night studying for entrance exams. The popularity of late-night programming revives radio, which was in the process of yielding its prominence to television. A major attraction is the ability to call popular disk jockeys directly and ask for a favorite song. Now that it connects listeners to disk jockeys, the telephone begins to leave its former place ensconced by the front door of the house, and moves into the parlor and even into individuals' rooms.
