DDI Media’s Billboard Products

DDI Media offers our advertisers options in billboard advertising. We have a substantial selection of traditional static billboard faces in addition to strategically placed digital billboard locations. Our digital billboards offer incredible flexibility with how and when you show your message(s). Our static billboards are excellent in delivering a clear and constant message over the course of your campaign.

Additions can also be used on most static billboard designs. These draw viewers’ eyes with elements such as light and 3-D objects that surpass the normal borders of the sign. No matter which type of billboard fits your needs best, DDI offers complimentary design service as part of any billboard product or service.
