When the Motion Picture Association (MPAA) rating system was introduced in 1968, it included an "M" rating for "Mature Audiences". However, parents found it incredibly confusing because they could not tell if "mature" meant appropriate for teenagers or strictly for adults.

If "year 70" was a typo or a misremembered classification for standard ESRB or TV ratings, you are likely looking at the bracket used in modern entertainment.

To fix this confusion, the MPAA officially changed "M" to "GP" (General Audiences, Parental Guidance suggested) in 1970. By 1972, this was tweaked again into the "PG" rating we know today.

This demographic heavily favors the "Adult Standards" or "Nostalgia" radio format. It highlights Big Band, classic vocalists, and the pre-rock or early rock era.

Titles rated M are suitable for persons ages 17 and older. This category represents a massive, highly profitable corner of the gaming industry known for intense action, complex storytelling, and dark themes.
