Also, for the BC1 & BV1 range, sales sufferred towards the end of its life as it was 4:3, not 16:9
At the time, I worked in a retail group that had 8 B&O shops and 5 "multibrand" stores. Without doubt, as the widescreen ratio gained a foothold, the idea of a £2 - 3000 square TV got harder and harder to sell - even given the superb sound & picture. That was the case in the UK, anyway.
The same issue impacted on sales of the fairly short-lived Beocentre AV5 - brilliant sound, great picture, but 4:3. Avant 28 outsold this product by many multiples, simply because it was widescreen.
