I think Deirdre Maloney (Co-Founder, BPMW Agency) describes the definition of an influencer best - a person that can take an idea, a brand, a concept that is not in the mainstream consciousness and can bring it to the mainstream consciousness.
A short artistic documentary written and directed by Paul Rojanathara & Davis Johnson, produced by R+I Creative on the idea of the “Influencer marketing”, which emerged in marketing in the 50s and is still relevant today.

The film focuses on the concept of “Lifestyle Culture” in the areas of music, fashion, and entertainment and it does not pretend to offer an analysis of what is influence under all its forms (economic, political, environmental etc.)
INFLUENCERS is a short documentary that explores what it means to be an influencer and how trends and creativity become contagious today in music, fashion and entertainment.
The film attempts to understand the essence of influence, what makes a person influential without taking a statistical or metric approach.
Written and Directed by Paul Rojanathara and Davis Johnson, the film is a Polaroid snapshot of New York influential creatives (advertising, design, fashion and entertainment) who are shaping today’s pop culture. “Influencers” belongs to the new generation of short films, webdocs, which combine the documentary style and the online experience.
For a bonus note, the first season of “In-depth series”, a video content platform planned in parallel to provide an in-depth understanding on the topics mentioned in the film, will debut online Wednesday, November 17 at www.influencersfilm.com

A very brilliant cross-over project combining film and online experience.
Enjoy!
