You’re at a festival, and your mate couldn’t make it. It’s a shame, but there’s not much you can do to commiserate, right? Well now, with the emergence of live streaming apps, you could stream performances from their favourite band for them to watch in real time. You could share streams of pets behaving strangely, gaming, or a friend making a cake. The possibilities of these apps are just being realised with the recent releases of Meerkat and Periscope, where anyone can set up a live stream with nothing more than their smartphone.
