Recently, people have been asking some very basic questions about the selfie stick—like "exactly where did it come from?" Stores have been selling out of the accessory, and it's become the hot new thing. Yet, at the same time, most people have barely just started becoming aware of it, and still a very small percentage of people actually own one. The mass frenzy about selfie sticks has only just begun.
For a quick sense of how fast the selfie stick craze is growing, we can look to Google Trends. Although it's not the most perfect barometer for all data analysis, in this case it gets the point across. Notice how the phrase came out of nowhere in 2014, and only particularly in the last few months.
