Celebrity avatars tend to follow trends in popular culture. And like items in popular culture, they may quickly become epidemic and then disappear. There may be a variety of motives behind the use of these avs. People may use them to express personality traits or social issues that are associated with the celebrity's image (sensuality, intelligence, power, corruption, rebellion, etc.). The user may identify with, desire, or be poking fun at these attributes. They may hope to bolster their self-esteem and identity by establishing their connection to the celebrity. They may simply wish to display a knowledge of current events in pop culture. Celebrity avs also advertise one's specific interests in entertainment in order to find like-minded users: "Hey, I like Seinfeld! Anyone else out there like Seinfeld?"
