The centerpiece of the campaign in New York City is a 14 foot screen displaying commercials in 3D throughout February. The physiologically correct 3D content created by N4D is a first in digital outdoor advertising and is expected to lead the way for this type of application.
"To bring high definition 3D content to a high profile location like Grand Central Station, we needed a partner with the experience and resources to meet our clients' needs. Our partner N4D created a custom 3D solution that exceeded our expectations and their team overcame every challenge we presented to them. We look forward to a continued expansion of our 3D offering with N4D," said David Lane, Vice President Digital Media CBS Outdoor.
