MNN has been particularly recognized for its non-traditional sponsorship model, an approach that has attracted many of the world's leading brands. Unlike the vast majority of websites, MNN does not sell standard advertising, offering instead exclusive, yearlong sponsorships for each of its content categories, such as transportation, safety, energy, family activities, and travel.The ability to extend that model across a larger audience is already attracting significant interest, with Wal-mart's announcement that it will be partnering with the company on a new content channel which will profile individuals, organizations, businesses, and products that are making a positive impact on the environment.
