This article traces the emergence of the basic paradigm for early diffusion research created by two rural sociologists at Iowa State University, Bryce Ryan and Neal C. Gross. The diffusion paradigm spread to an invisible college of midwestern rural sociological researchers in the 1950s and 1960s, and then to a larger, interdisciplinary field of diffusion scholars. By the late 1960s, rural sociologists lost interest in diffusion studies, not because it was ineffective scientifically, but because of lack of support for such study as a consequence of farm overproduction and because most of the interesting research questions were thought to be answered.

作为科学成长范例的创新范式的起源和发展

本文追溯了爱荷华州立大学的两位农村社会学家 Bryce Ryan 和 Neal C. Gross 创建的早期传播研究基本范式的出现。传播范式在 1950 年代和 1960 年代传播到一所无形的中西部农村社会学研究人员学院，然后传播到一个更大的跨学科领域的传播学者。到 1960 年代后期，农村社会学家对传播研究失去了兴趣，不是因为它在科学上无效，而是因为由于农场生产过剩而缺乏对这种研究的支持，并且因为大多数有趣的研究问题被认为已经得到解答。
