How many more times? If a regular TV costs $100 then they’re making $20k plus marketing data. The PrivaTV would need nearly a $7000 markup for the same return.
Obviously these are made up numbers for illustration. I think that for big manufacturers it’s not worth it for the return and amount of effort they would need to spend. Maybe a small manufacturer could do it. Maybe that would spur the big guys to buy them out and take it over once the hard work is done.
