Final answer:
Buzz marketing can be facilitated through online message boards and networking sites, and it markets products without letting consumers know that they are being marketed to.
Step-by-step explanation:
A) It can be facilitated through online message boards and networking sites.
Buzz marketing is a strategy used by companies to generate excitement and word-of-mouth about their products or services. One way this can be done is through online message boards and networking sites, where people can discuss and share information about a particular product or service. This can help create buzz and generate interest among consumers.
B) It markets products without letting consumers know that they are being marketed to.
Buzz marketing is often done in a subtle and covert way, with the goal of creating natural and organic buzz around a product or service. This means that consumers may not even realize they are being marketed to, as the marketing message is integrated into their everyday conversations and interactions.
