Sony Product Catalog Hi-Band Beta Related 2 Books Around 1985 and 1986 I found these old items. Two catalogs explaining Sony's video decks and high image quality. Beta certainly had high image quality, but it lost the battle for dominance to VHS, which offered longer recording times. You might be able to compare them side-by-side, but it's hard to tell when viewing them separately. I think the human eye gets used to the image. That's enough explanation. I'm including a newspaper article from the 1985 shareholders' meeting, which is different from today. These are items that have been stored for a long time.
