Huffington Post: Periscope was voted the Apple App Store 2015 App of the Year. I discovered Periscope, the app that was bought by Twitter before it even launched, through my friend Africa Miranda. She came to visit me at my office and said, "I'm going to scope this." Confused, I said, "Do wha...?" She then proceeded to introduce me to, what I imagine, will become our modern, interactive, version of television: Periscope. Warning: it's addictive.
