“Which market segment is the one that is totally saturated with digital signage five years from now? (Is there a market where the gold rush is over and every new opportunity has been already taken?)”
The one market segment I think will be saturated five years from now will be the Hospitality and Casino sectors.
As mobility, interactivity, social networks, and all of their additional capabilities transform consumer patterns, the opportunities for creating deep, effective customer engagements anytime, anywhere will keep expanding throughout that industry.
With millions of digital signs now operating worldwide, it becomes increasingly difficult to find a venue without digital signage. Major verticals include: Retail, Entertainment, Transportation, Hospitality, Corporate Buildings, Healthcare, and Banking. I don’t think the Gold Rush is over. There’s just a new one about to begin with the advancement in display technologies on the way. Everyone wants the brightest and the best and can’t resist it when it becomes available.
