The ability to rapidly change buying patterns and product or service acquisition and activity to a growing number of consumers is defined as an influence network.[7] Social networking sites and blogs allow followers to "retweet" or "repost" comments made by others about a product being promoted, which occurs quite frequently on some social media sites.[8] By repeating the message, the user's connections are able to see the message, therefore reaching more people. Because the information about the product is being put out there and is getting repeated, more traffic is brought to the product/company.
