This has been the year of Facebook. Its stock price has increased by around 50% as it continues to assert its dominance in user activity and digital ad revenue.
It undercut one of the companies trying to catch up with it, Snap, by adding a similar feature, Stories, to its increasingly dominant Instagram service. And scrutiny surrounding its role in the 2016 presidential election continues to grow, as politicians seek more information about Russia's involvement on Facebook in the weeks and months leading up to last November.
