Reading through the list makes you realise how much hype manufactures put out and how little it reflects the volume of cable they sell. However, it's worth noting that some of the manufacturers you will never have heard of. This is because these manufactures are making the cables for well brands.
For example, when you buy a product and it comes with say USB or Audio cables, it's these little known manufacturers quietly making them in the millions, therefore selling a tonne of cable.
I hope you find this as interesting as I did!
