Everyone knows Pokemon. And most people have some sort of emotional connection to the series. But a lot of old fans have drifted away from the series…until now. After less than a month, Pokemon Go is already at the top of the Apple App Store chart. For those that don't know, the latest Pokemon iteration allows players to walk around the real world, capture Pokemon, and level them up. Certain predetermined locations are gyms and Pokestops where players can battle or get supplies, respectively. Walking or driving through neighborhoods, it's difficult to miss groups of all ages walking around with their eyes glued to their screen. At this point, calling the game a "viral hit" seems like an understatement. Surprisingly, this was achieved with only a small marketing effort.
