This document discusses secondary research conducted on age ratings and classifications. It examines the British Board of Film Classification (BBFC), which rates and restricts films in the UK. The BBFC assigns age certificates like 15 and 18 that restrict what younger audiences can view. This secondary research was useful for planning the age rating for the author's slasher trailer. Based on the looser restrictions and larger potential audience, they chose to target a 15 certificate to increase their budget and production quality.
