eMarketer estimates that 88.0% of 18-to-24-year-old internet users in the US will use Facebook this year, as will 78.6% of those in the 25-to-34 range. This works out to 58.7 million millennials logging on to Facebook at least monthly in 2015 - and many are likely doing so to check out the news. According to February 2015 research by The Media Insight Project for the American Press Institute and NORC at the University of Chicago, 57% of US millennials checked Facebook at least once a day to get news and information, with 30% logging on several times a day and 14% doing so nearly constantly. No other social site came close in respondents for this frequency. Because training resources are Facebook's top request from its advertisers, the social media giant launched a series of courses on everything from how to create an ad to digital buying.
