Contrary to what you think - I mentioned RPTV's because you said there was no screen size worthwhile for watching movies on.
RPTV's were great for watching movies on, they appealed to those interested in home cinema. IMO they were fairly common in the high st and retail parks - the majority of manufacturers produced RPTV, Toshiba, Sony, Samsung, Optoma (ThemeScene), Phillips, Thomson, Bush.
As for viewing distance, I said it applied then as it does today, when you look at the range of screen sizes 21" - 65" and the source was only SD., it's obvious why it applied. Sit to close and the image was dreadful.
Then when I mentioned RPTV's were fairly common/readily available you claimed almost no one bought them - go figure.
That's just clutching at straws, you ain't got a clue how many were sold, you don't even have a clue how many different models were available, and you say I should know what's available in other countries, you don't even know what was available in your own country.
I don't care how many bought RPTV's, the point is large screens were available. It's no good you just saying no one bought them so 36" was the max screen size and that makes the distance factor a mute point, they were on sale - fact.
Never claimed no such thing, that's you making up your own conclusion(s)
I said they were fairly common/readily available, from memory that's how I remember it, Curry's/Dixons/Courts had a shop floor full of them.
You keep referring to THX recommendations, well there were recommendations for SD too...........The calculator below gives you veiwing distances for SD Based on Visual Acuity.

If you want to dismiss/ignore large screen RPTV's and SD viewing distances because it suits your agenda that's entirely up to you, but don't try and put worRAB into my mouth.
