Periscope, Twitter's new live streaming app, has quickly shot to prominence, raising new concerns about privacy, as more people put their everyday lives on the air more easily than ever before.

On March 26, the day the app launched, dozens of New Yorkers broadcast live video of a building that exploded into flames before news media arrived on the scene.

The app allows users to broadcast live video from their smartphone cameras to anyone on the internet, either publicly or privately to a selected list of people.

Thanks to Twitter's considerable marketing push for the app, it quickly asserted itself as a rival to Meerkat, a similar live streaming app introduced at the SXSW festival only a week earlier. Celebrities including Tonight Show host Jimmy Fallon have already jumped on the bandwagon, giving fans a live backstage look at their productions.

People are already using Periscope and Meerkat for a wide range of activities, from breaking news live at the scene, to more mundane activities such as a man browsing through the contents of his fridge.
