I'll answer the easy question first. The reason they don't make end view tubes is that it costs a lot of money and take an incredible amount of work to make tubes. So, they need to make the most of the tubes they make, and this means being able to get the most money for them. So they have to be beautiful, large, expensive tubes. The character size in an end view tube is limited, vs that in a side view tube, so they only make side view tubes. It's what people will pay lots of money for.
