Which audience age category is most attactive to today's moviemakers? why?

According to the text book "Media/Impact" written by Shirley Biagi, the target audience for today's movie makers are mature audiences over the age of 30 and children because these are the people who are most interested in movies. Children because they bring their parents to the movies and older adults because they are more settled in their life and use movies as a major source of entertainment in their lives.

I can understand the reason for their target audience. Younger adult individuals tend to be more active and seek out more than one source of entertainment. Children are tempted by the popularity of the characters and images of their favorite action stars being popularized on the big screen and tend to be drawn to the overall experience of the movie theaters.
