Advertising is rough. People get jaded, technology gets old. Viral videos aren’t what they used to be. It’s not just a case of throwing a simple website up and hoping they come to you, you have to actually work for it.
Projectors seem to be where it’s at these days. Companies are using them on walls, pool tables, and now train stations. Waterloo Station in the UK is the site of the latest example, using AdTrace, created by two companies in Great Britain. I think it’s safe to assume that this technology will be coming to the US in the near future.
