WOM means Word-of-Mouth
WOM comes from the marketing and goes to exchanging the view of consumers. WOM is powerful because it is fair and it comes from well-known. People talk more often about a (good) product, but as soon as marketing comes up it is called the WOM. When you have had a fun day at an amusement park and talk to your friends about it, it is also WOM.
