Final answer:
In a web address, ".com" signifies commercial. The most important commodity in a postindustrial society is information. Examples like comic books and Wikipedia are media, carrying significant cultural influence.
Step-by-step explanation:
In the web address, the ".com" signifies commercial entities. This is part of a domain name, which indicates the nature of the website or the entity that owns it. Other common domain indicators include .edu for educational institutions, .gov for government websites, and .org for nonprofit organizations. These can often offer more trustworthy sources of information than .com websites, as they typically represent official or institutional entities rather than businesses.
Regarding the most important commodity in a postindustrial society, the answer is information. Unlike an industrial society that focuses on the production of goods, a postindustrial society emphasizes the role of information and services.
Finally, comic books, Wikipedia, MTV, and a commercial for Coca-Cola are all examples of media. These are all methods of communication that reach a wide audience and have a significant influence on culture and society.
