My (and HuffPost's) reading of the Experian graph is that 18% of households with Hulu or Netflix have no cable TV service, while cabletv.com reverses it: 'only 18% of “cord cutters” have Netflix OR Hulu.'
I didn't go through the sign-up form to download the study itself, and the graph appears not to have been made by Edward Tufte, so it's hard to say for sure. Anybody read the actual study?
The plot is essentially saying that if you compare the "average household" to the households of Netflix and Hulu subscribers, customers in the latter are about 2.5-3 times more likely to be "cable cutters". This is what what I would call "Netflix and Hulu killing cable."
The whole premise of their article is flawed on a misreading of a figure. The study they cite contradicts their claims.
Here are their slides: http://www.experian.com/assets/marketing-services/brochures/...
> ... about 11% of all Americans subscribe to Netflix.
Netflix's latest numbers show 35.7 million subscribers, but the author is only giving credit for one person per Netflix subscription. With 115 million US households (http://quickfacts.census.gov/qfd/states/00000.html), that gives Netflix access to 31% of households.
