If you've been out in a public space today, i'll put money on the fact you would have seen some digital signage.
The idea is simple from the vendors point of view, place screens where wandering eyes will see them & market products to generate an income. But the probelm comes when you want to change this content. The old way of working was to upload this content to a memory stick and 'plug & play'. This model doesn't really work too well anymore beacuse the speed in which advertisers want their new messages out there is as fast as possible. By having a cloud based platform where the advertiser can log on and update their sceens is a relevation in the signage industry.
Using EventBeat make updating your digital signage a doddle.
