Four Quadrant Picture

A Four Quadrant Picture is a marketing term used to describe a film targeted to all audience quadrants: men over 25, men under 25, women over 25, women under 25. 

Usage
In the movie business, and it is most definitely a business, everyone is looking to maximize the audience for their picture. A four-quadrant picture is that magical type of film that attracts parents and kids, men and women, and brings in huge amounts of revenue on opening weekend. In the term “four-quadrant,” the quadrants refer to gender (male and female) and age (under 25 and over 25). 
For most studios, the goal is to get enough details to line up so that they have broad-based, family-friendly appeal in designing a blockbuster or four-quadrant film. An important aspect of getting that appeal is the ratings system. An 18 Rating can be the kiss of death for a studio trying to market a film featuring pre-teen characters. A lowering from PG-13 to PG can mean millions more in revenue as parents feel more comfortable bringing young children to a given film like Evan Almighty.

Examples
One of the most famous four-quadrant, blockbuster films is Star Wars and all of its sequels. Jaws is another landmark blockbuster film. Other more current examples include Night at the Museum, Journey to the Center of the Earth, Shrek (1-3), Spiderman (1-3), Pirates of the Caribbean (1-3), andWall-E.

Implications
Another interesting by-product of the rise of four-quadrant films in the industry is cross marketing. Those films often are associated with toys and other products that both advertise the film and bring in revenue on their own. In addition, four-quadrant films are powerful vehicles for product placement advertisers looking to show their wares to the largest audience possible.
On the down side, many wonder how much effort is placed on credible, engaging story lines as opposed to marketing opportunities in these behemoth cinematic endeavors.
