Quad/Graphics (QG), a publicly-listed media giant that specializes in dead tree products and related services, has invested in YouTube-certified online video marketing and advertising company Pixability.

The size of the investment was not disclosed, but an earlier SEC filing shows that Pixability recently closed $4.1 million of a planned $6.6 million Series B round.

By acquiring a minority interest in and partnering with Pixability, QG is betting on online video and YouTube in particular.

The classic media house’s chairman and CEO, Joel Quadracci, says:

“Online video is the fastest growing marketing channel in the world today, and Pixability’s proven approach to YouTube marketing and advertising fits well with our media solutions video offering, which includes strategy, concepting, creating, producing and delivering online video for leading brands.

Like Quad/Graphics, Pixability understands the importance of getting the right message in front of the right audience to trigger the right action. Together, we offer a robust, single-source solution that creates, optimizes and connects content across multiple channels in a way that provides the greatest return on marketing spend.”

Pixability basically works with brands, e-retailers and agencies to improve video marketing results. With the funding, the company will continue to expand its cloud-based video analytics and marketing software platform.
