A billion mobile subscribers were added in the last 4 years to leave the total users of mobile communications standing at 3.2 billion - almost half the world's population. Mobile technology (and devices) form a critical part of innovation technology, which in the 21st century is referred to as the "Third Platform". Mobile (or Smart) devices - portable tools that connect to the internet - have become a part of our lives. In the last quarter of 2010, sales of smart phones outpaced those of PCs for the first time, according to data from IDC. By 2014, more smart devices could be used to access the internet than traditional computers. There is an obvious move to an increasingly mobile world, and this is creating new players and new opportunities for a variety of industries. According to IDC: Over the next four years, the number of people accessing the Internet through PCs will shrink by 15 million as the number of mobile users increases by 91 million. In 2015, there will be more consumers accessing the Internet through mobile devices than through PCs.
