In mid 1999, Joe Holland, National Advertising Manager at Rentrak Corporation, was introduced to a new substrate that did not have the limitations of other materials. Rentrak Corporation is the world's largest revenue-sharing distributor of videocassettes. Headquartered in Portland, Oregon since 1988, the company currently serves more than 10,000 video retail stores in the United States and Canada. These materials range from small POP signage to large, full-color window posters. While all those materials can be effective, they all have limitations that impact compliance.
Paper needs adhesive, or a holder of some sort.
The bottom line is, the easier the material is to apply, the more likely it is to be used. The primary criteria I have for my promotional displays is to have an effective message delivered through a media that is user friendly. You remove the backer sheet and place it on virtually any surface. If it's not positioned properly, you simply move it.
