Warning sign: Facebook teen-age use slips for first time ever
Facebook usage among 12 to 17-year-olds will decline for the first time this year, eMarketer estimates. Meanwhile, eMarketer's latest forecast for the first time has Snapchat beating both Instagram and Facebook in terms of total users aged 12 to 17 and 18 to 24.
Why it matters: This marks the first time eMarketer has ever predicted a decline in Facebook usage for any age group and usage among people 24 and younger will grow more slowly than previously forecast.
