Word-of-Mouth Marketing (WOM Marketing)
You loved the movie. You laughed. You cried. You plotzed. So you went home and you told two friends. You screamed through tears and laughter, "You must see this movie."
It was the words from your mouth that marketed that movie. No studio paid you. You received no commission for un-asked-for praise. You just marketed it, word of mouth.
So go see the movie. It'll reach ya. Word.
