Which of the following businesses utilizes the content provider Internet business model?

The content provider Internet business model is characterized by businesses that primarily focus on delivering information, news, or entertainment to their users. CNN.com is a prime example of this model as it offers a vast array of news articles, videos, and live updates related to current events and various topics such as politics, health, and technology. Its revenue is largely generated through advertising and subscriptions, typical of content-focused platforms.

In contrast, Amazon.com is primarily an e-commerce site, selling products directly to consumers. eBay.com operates as an auction and shopping website where users buy and sell products directly, focusing on transactions rather than content delivery. Similarly, Motocross.com, while it may provide specific niche content, does not primarily function as a content provider at the same level as CNN.com. Thus, CNN.com stands out clearly as a business employing the content provider model in the Internet landscape.
