IPTV will not his mass distribution until the media to deliver it becomes available. Meaning, the fiber networks have yet to be run to 90% of the country. yes, there are cable and telco providers that boast high speeds. But at a premium price. $60 to $80per month for internet.
You keep making weird claims about internet TV that are just flat out wrong. I've been getting by just fine as a cord cutter with standard cable internet for a year now for $45. $60-$85 internet plans are not required to watch streaming video any more than the 5Mbps upload you said we needed earlier.
Internet TV doesn't have to take over 100% of the market to cause major problems for Dish and other providers. That can happen without all the people who don't have good broadband. Netflix has 50 million subscribers now. Is 50 million subscribers not mass distribution? If it's not than Dish's 14 million subscribers certainly isn't either.They are doing just fine even without all those people with no broadband access.
