IPTV is basically a fusion of voice, video, and data service. It is not a new idea or, rather, development, but it is a result of high bandwidth and high speed Internet access. In earlier days, the speed of the Internet did not suit the concept and, as a result, it affected the voice and video services. In recent times, the speed of Internet and bandwidth has increased considerably, making IPTV prevail and become reasonably successful. Also, first generation Set Top Boxes were prohibitively expensive. Technology costs now permit a viable business model.
