Re: It's marketing lies allowed to become reality.
Erm, firstly TVs and then subsequently monitors have always been measured by the size of their diagonal screen dimension. When I say always, I mean at least many decades, at least 5 of them to my personal knowledge. It's the industry standard, nothing to do with marketing.
They also have traditionally been marketed by the diagonal size of the CRT, in spite of the fact that the screen bezel will make the actual picture smaller. This stems from the fact that beam control is hard at the edges of CRTs, so the bezel hid the wavy edges and distortions.
Some of this is no doubt marketing -- bigger numbers are better -- but some of it may be because early TVs actually used round CRTs, with a rectangular mask over the front to delineate the picture area. A 10" CRT was 10" diameter before you put the mask on it. The diagonal measurement would have been closest to the actual CRT diameter.
