Cyber security, the internet of things, and 3D printing will be major technology trends to watch in 2015. Security will be a top priority for companies as mobile devices and connections reach 10 billion. The internet of things will connect over 26 billion devices by 2020. 3D printing sales are expected to double in 2015 as prices decrease. Social media will see more selfies, charitable challenges, and personalized advertising. Content will need to be mobile-first, contextual, and personalized across multiple devices.
