” Facebook can’t stay on top forever—not with so many new social apps nipping at its heels, anyway. A new survey of 7,200 U.S. students by research group Piper Jaffray suggests that the social giant is in fact dramatically losing teen users, despite what COO Sheryl Sandberg might want us to believe. In spring 2014, 72 percent of respondents between the ages of 13 and 19 reported that they used Facebook; by fall 2014, that number fell to 45 percent. By all accounts, that’s a massive drop for a company that’s downplayed its waning popularity among the key demographic of younger users for the last year.
Facebook proper may have fallen from grace, but Facebook-owned Instagram is on the rise among teens. The number of teens using Instagram nudged upward from 69 percent to 76 percent in the same time period while Twitter fell slightly from 63 percent to 59 percent, Google+ dropped considerably from 29 percent to 12 percent and Twitter, Pinterest, and Reddit held steady.”
