Going mobile. As the owner of four of the five most downloaded apps in the Apple iOS App Store and Google Play in October 2014, Facebook is taking the mobile scene by storm. The social media giant now accounts for 20 percent of all the data that flows through mobile phones, thanks in large part to its early-2014 adoption of its “autoplay” feature, which results in a video included in a Facebook user’s newsfeed to automatically start playing unless the user has turned the feature off—more video streams mean more data traffic. Moreover, Facebook’s advertising model has adapted to reflect Internet users’ exodus from their desktop computers; indeed, mobile devices currently account for two-thirds of the company’s advertising revenue.

Trial tweets. A federal district court judge in New York City refused to grant a new trial to lawyers convicted on immigration fraud charges based on the convicts’ claims that a juror’s tweets revealed a bias against them. During the immigration lawyers’ trial, the juror—a “romantic suspense writer”—tweeted things like: “I suppose it’s inappropriate to ask judges, prosecutors and witnesses to talk to your MWA [Mystery Writers of America] chapter after the trial ends?” and “I really like our judge . . . she’s the kind of person I would be interested in talking to.” (One of the tweets even ended with “#juryduty rocks.”) U.S. District Judge Ronnie Abrams held that such tweets didn’t express the juror’s views about the defendants or the strength of the prosecution’s case.
