Matthew Pellegrini checks his phone while playing Pokemon Go at the NorthGate Center mall in Dallas as his friend Ashley Jenkins charges her phone with an external battery. It's only been available in the U.S. since Thursday, but Pokémon Go has officially become a viral phenomenon. If you're curious why it seems everyone is talking about Pokémon in recent days, let's catch up. Last week, Nintendo and The Pokémon Company launched Pokémon Go, a game for iPhones and Android smartphones featuring the classic video game franchise where players catch and train special creatures called Pokémon. What makes the game special is its use of augmented reality, where Pokémon will appear as if they've been spotted in the real world. The game presents a map powered by GPS, using real-world locations to spot Pokémon and collect items.
