What's Behind Your Smartphone Icons?

In our daily life, we regularly use various multimedia services such as voice and video calling (Skype, Facetime, Google Talk), video conferencing (WebEx, Telepresence), TV delivered over the Internet (IPTV), video on demand (YouTube, Netflix, Amazon, Google movies), and instant messaging (texting). We also use other apps that often include some of the above multimedia services such as geo-tagging, online games, and assisted living.
