So according to this article, the SEC Network costs subscribers $16.80/year. The article quotes revenue of $550 mil, meaning about 32.7 mill subscribers.
The article from Fox on the thread from the other day said they have 67 million subs at about $8/year ($0.66/month) for $537 mill in revenue.
So which is it? Those numbers, other than annual revenue, seem quite far apart.
