Over the past fifty years, the speech communication discipline has confronted more frontiers than most. Earlier frontiers involved a preoccupation with physiology and an application of electricity to speech communication in a myriad of ways. Another reliable source of frontiers and one that led to fragmentation or a speech department of unified diversities is the seeking of specializations within speech communication. Later frontiers revolved around a fascination with intercultural communication and the necessity to deal with communication across cultures. A more recent and more rapidly advancing frontier concerns organizational communication. Both of these frontiers--organizational communication and intercultural communication--are of equal importance. Both are joint ventures with other disciplines and as such they reflect the continuing frontier of working out satisfactory relationships with related fields of study. A divisive frontier that challenges the profession is one of interaction, of fitting metaphoric and experientially derived notions that are useful and operationally valid into a statistical world.
