I realize there are some 3d channels that came out in 2010 that are now defunct. I attempted to scrub the list to only include active channels. If it is not entirely correct, I apologize. I know the Comcast article is dated, however Comcast has followed through; their 3 year old insights are pretty accurate to what has happened.
Go TDEY
That article is from 2010 and I don't think that list is of existing channels. Can you provide the ones you indicated in your question? TY
