This is a lot more challenging than you think it is.
I want you to identify a business that only sells to other businesses. For example, Verizon sells to both consumers and businesses. Ebay is focused on consumers, not businesses.
Companies like Caterpillar, IBM, CISCO, on the other hand, sell their products and services only to other businesses.
Find one of these types of businesses (not necessarily these particular ones) on the internet and look at its web pages. What does the firm emphasize? What is its focus? What does the site "talk" about?
How do you perceive the messages to be different from what companies that sell only to consumers say and do?
