The second emerging business I chose was Augmented Reality & Virtual Reality, this is not a newest business, but it always used in traditional vr entertainment shops, rather than some new industries.
But I found some interesting case about VR and AR, the first one is British Museum offers virtual reality tour of Bronze Age.

The British Museum is running a trial of virtual reality technology with a view to offering it as a permanent tool to explore its collection. Families will be invited to navigate a virtual reality Bronze Age roundhouse and interact with 3D scans of objects.
The second one is Instagram AR Filter. Augmented reality (AR) filters are computer-generated effects that are designed to be placed on real-life images. AR filters operate with your camera to add a layer of imagery to your image’s foreground or background.

I think all of these technologies can used in our daily life, like restaurant and coffeeshop, etc.
