Quill.com and NBCUniversal announced today a multi-year extension to their licensing partnership for the Dunder Mifflin line of office products, inspired by the TV show “The Office,” which aired its series finale last May.

The Joy Tashjian Marketing Group brokered both the original licensing deal and this renewal.

“On ‘The Office,’ Dunder Mifflin is a struggling company, but in the real world it’s a thriving brand,” says Paul Bessinger, director of innovation, Quill.com. “Businesses all over the nation have learned that it’s fun to have a bit of ‘The Office’ in their workplaces.”

More than 171,000 real-world offices have purchased Dunder Mifflin products since the line debuted in 2011 with Dunder Mifflin Copy Paper. The line now also includes Dunder Mifflin Sticky Squares, Yellow Paper with Straight Lines, Sharpies and more.

“The success of the real-life Dunder Mifflin brand is helping to keep the legacy of ‘The Office’ alive with the show’s many fans, and we are thrilled that it will continue for years to come,” says Kim Niemi, senior vice president, NBCUniversal Television Consumer Products Group.
