You may think it's for free. Comcast uses the Telvue cloud and it's pay me now or pay me later. Most of the clouds use Princeton Servers since they are the best and most use Telvue software since it is also the best. As hard as it is for me to believe there were people who were against the automobile when it first got started.
Take a wild guess who's servers Charter uses because they are the best. Telvue sells the best servers available. If not why would both Charter and Comcast use them when they could have any they wanted. Why do they both use Telvue software ? When your looking for the very best of everything in the start of the new world of streaming video you look for Telvue.
