![Primary Device Used When Sharing Social Content By Channel, Q2 2014 [CHART]](http://www.emarketer.com/images/chart_gifs/176001-177000/176457.gif "Chart - Primary Device Used When Sharing Social Content By Channel")
eMarketer estimates that 40.1 million US consumers will use Pinterest via any device at least monthly this year—and based on recent data, it’s likely that most of this activity will take place on mobile. According to Q2 2014 research by ShareThis, US internet users logging on to Pinterest via mobile were three times more likely to pin than desktop users.
Three-quarters of Pinterest sharing took place on a mobile device. In comparison, Facebook—which claimed the overwhelming majority of all social shares—saw just over half conducted via smartphone or tablet.
That the majority of pins happen on mobile makes sense when one looks at how much time Pinterest users spend with the social site on different devices. In February 2014 research by comScore, mobile dominated desktop when it came to share of Pinterest time, claiming 93% of all time US Pinterest users spent on the social platform, compared with just 7% for PCs.
