Another feature of mobile phones, that may prove to be of particular importance to addictive behavior, is 'texting' either directly or through social media such as Twitter and similar applications. Recent surveys indicate that young people are starting to discard Facebook in favor of Twitter, particularly as their parents create accounts and ask to be 'friended' (Madden et al.., 2013). These types of applications are growing and allowing more and more features such as Vine, which allows users to create six-second videos to share with followers. The overarching feature of these applications is their 'stickiness', the propensity to have users utilize the app frequently. Stickiness is a result of their business models that rely on the growing heap of data on user behavior to share with advertisers for targeted marketing.
