Final answer:
Convergence theory explains how societies move toward similarity over time as they develop, shaping a global culture through the diffusion of ideas and practices.
Step-by-step explanation:
The theory that suggests if everyone watches images that promote the same values, eventually everyone will converge into one global culture is known as the convergence theory. This sociological perspective explains how societies become more similar over time as their economies and other societal sectors develop. A key aspect of this theory is the diffusion of ideas, concepts, or artifacts, which are spread to individuals and groups, resulting in the adoption of new social practices. For example, television and the Internet have been instrumental in broadcasting U.S. cultural norms and values across the globe, which in turn, shapes and promotes a collective global culture. However, it is important to recognize that while convergence theory identifies a trend towards cultural unity, there remain diverse perspectives on whether this leads to a stifling of creativity or continues to allow for innovation and cultural variety.
