When Goosebumps used to air televised versions of their books on television (I recall them being Friday night specials on Fox now and then) they used to say "This has been rated GB-7 because it may be too spooky for children under seven". -irrelevant part clipped- Of course, this was before TV ratings started in 1997 (the books were on TV in 1995-1996).
Yeah, I remember other shows doing it too.
Like Ren & Stimpy and Are You Afraid of the Dark, for example.
ps: what, GB-7? where do you live? The US TV Rating standard has always been this (with the appropriate TV prefix):
Y
Y7
G
PG
14 (dunno why they made it 14 though :?, maybe to avoid copying from the MPAA standards -shrug-)
