The system went unchanged until 2002, when record labels affiliated with Bertelsmann began including specific areas of concern including "strong language", "violent content", or "sexual content" on compact discs alongside the generic Parental Advisory label.[5] The Parental Advisory label was first used on music streaming services and online music stores in 2011.[6] That year, the British Phonographic Industry (BPI) revised its own music censorship policies to incorporate more prominent usage of the warning label.[7]
