The document discusses the British Board of Film Classification (BBFC) system for classifying videos, DVDs, and some video games by age rating. The age ratings include U for ages 4 and up, PG for ages 8 and up but some scenes may not be suitable for younger children, 12A means anyone 12 and over can watch but those under 12 must be accompanied by an adult, 15 and 18 ratings restrict viewers to those ages and older, and R18 is legally restricted to explicitly sexual content and can only be viewed by adults in licensed establishments.
