Stars are a familiar and popular symbol, with scales of one to three or five stars commonly used. Ratings appear in guide books as well as in the media, typically in newspapers, lifestyle magazines and webzines. Websites featuring consumer-written reviews and ratings are increasingly popular, but are far less reliable.
