The British Board of Film Classification (BBFC) was established in 1912 to classify and censor films shown in the UK. It is responsible for classifying videos, DVDs, and some video games based on their suitability for different age groups, with the goal of protecting children and other vulnerable groups. The BBFC banned the film The Human Centipede Two due to its extremely violent and graphic content, but later gave it an 18 certificate after significant cuts were made. Studies like the Bobo Doll Experiment provide evidence that watching violent media can influence children's aggressive behaviors. The murder of James Bulger by two 10-year-olds was attributed in part to the violent media they were exposed to.
