grouped so that clicking one category
blocks all the categories a parent would
block along with it. For example, if
you click TV-G under ALL, then all the
categories associated with TV-G will be
blocked (TV-G, TV-PG, TV-14 and T V-
MA). The sub-ratings (D, L, S, V) work
similarly. So, if you block the L sub-
rating in TV-PG, then the L sub-ratings
in TV-14 and TV-MA will automatically
be blocked.
