Final answer:
Winn's essay does not directly address the change in the price of television sets, but instead focuses on the impact of technology and media, including television, on society and culture.
Step-by-step explanation:
Based on the information provided, the change in the price of television sets from their invention to today is not directly mentioned as a significant point in Winn's essay. Instead, the essay appears to be more focused on the social and cultural effects of television and film, as well as the broader impacts of technology and media on society. The references provided speak to the pervasive influence of multimedia on American culture, the socializing effects of television, the role of technology in major societal changes post-1945, and the relationship between technology, media, and different theoretical perspectives on social development. It seems the essay is discussing the broader concept of technology's influence on social norms, identity, and function rather than the specific economic aspect of television pricing over time.
