The document discusses the C2B (consumer to business) model of e-commerce. C2B platforms help buyers and sellers connect by allowing consumers to set product prices and find buyers that are interested. Specifically, the C2B model involves individual consumers selling products or services like blogs and social media accounts directly to interested businesses. Common examples of C2B businesses include sites like Craigslist, Etsy, and eBay that facilitate transactions between consumers and organizations.
