Here's some news:
A leading provider of next generation digital signage technology products and integrated services for establishing point of purchase marketing promotions and corporate communication networks, [along with] VISI Networks, a systems integration, multimedia design and production company specializing in customized narrowcast solutions for the out-of-home market, have formed a strategic relationship to create and manage a digital signage network for Laboratory Corporation of America® Holdings (LabCorp ®). Known as the LabCorp Health Network (LHN), this healthcare information and advertising network is currently installed in more than 300 of LabCorp’s more than 1,200 Patient Service Centers (PSC) in the U.S., reaching nearly 1.5 million viewers each month. By mid-2006, LHN will consist of more than 500 PSCs, ultimately reaching more than 80% of the patients and visitors to LabCorp’s PSCs.Hopefully they'll learn from AccentHealth and other past attempts at narrowcasting networks in healthcare providers' offices. On paper, though, it does seem like it's a model that should work, with content and ad creation/ placement and sales being the biggest hurdles to overcome.
