Farrell created the movie trailer.

In a world where movies started on time, and future projects were woefully under-marketed…One man would stop at nothing to advertise upcoming films before the feature presentation. 

I don’t know anyone who doesn’t like trailers. Try to find another invention that NO ONE dislikes. This guy managed to create a form of advertising that people pay to watch and hate to miss.

Farrell worked for, then ran, the National Research Group, Hollywood’s biggest marketing consultancy. Not only did he come up with the notion of showing movie teasers before features, but he also introduced such industry staples as tracking and test screenings. Did you ever wonder how you can read about a film’s weekend box office take on a Saturday afternoon? That’s tracking, and Joseph Farrell innovated and utilized it before anyone else did.

Recently, Farrell got into production with a first-look deal at Disney, but his real legacy will be what he did on the marketing side of things. He helped shape the practices of the entire entertainment industry. And that’s pretty cool.
