Your right, it is not written by Comcast. I stand corrected. (No holiday for me today, am working as I converse here. Thank you for you DD.)
It is just an opinion of whoever wrote the article talking about 3dtv and Comcast's vision. The old video is Comcast's CEO talking. Of course he is biased to cable. His vision of content and distribution coming together is seen in recent Netflix deals/partnerships.
