Bundesprüfstelle für jugendgefährdende Medien
While not obligatory, it is common to display a rectangular, black and white logo with "SPIO/JK geprüft" and the JK certificate granted. These movies may be additionally indexed (blacklisted) by the Federal Department for Media Harmful to Young Persons. JK/SPIO certified films are usually indexed within a month or two of publication with only a few exceptions, e.g. Virtuosity.
