According to a survey by Piper Jaffray, teenagers in the US are now using Snapchat more than Instagram for the first time. Of the 6,500 teens surveyed, 28% of respondents said they considered Snapchat their most important social network, just ahead of Instagram with 27%. With 18%, Twitter came a similar margin ahead of Facebook on 17%. In the same survey last year, only 19% of teens chose Snapchat as their most important social network, with over 33% choosing Instagram, representing a large shift in usage in that age group in just one year. Currently Snapchat has 100 million active users and rivals Facebook with 8 billion videos created every day.
