Whereas most marketing used to be broadcast to consumers and one-way communications, the advent of the Internet is now turning marketing into a two-way communication between the brand or merchant and the consumers. Facebook, among other services, has made this fun and easy for everyone, and is transforming the way that businesses interact with their customers. Consumers can share their likes, dislikes, and feedback among their friends and peers. Businesses can solicit customer reactions to new products and concepts, as well as provide special offers to reward their most loyal customers.
