According to a new report by IMS Research, approximately 25% of the TV sets shipped globally in 2011 were Internet-connected, a figure the research house expects to approach 70% of total TV shipments during 2016, resulting in more than $117 billion in revenues."Internet connectivity is becoming a standard on high-end TV sets, and it's increasingly being added to mid-end televisions," said Veronica Thayer, IMS market analyst, in a statement.The study also indicates that proprietary operating systems will remain the main type used by manufacturers in the next five years, although Android OS will start gaining presence and is expected to reach a significant share of the market by 2014. IMS Research's forecast indicates that during 2016, more than 80% of the connected TV sets shipped worldwide will have built-in WiFi, and close to 30% will have advanced user interface features such as motion, gesture or voice.
