    the LCD's has 4:3 ratio in dimensions because the CRTs has this ratio... and the digital camera(except highend DSLR) has 4:3 ratio because all computer monitor has this ratio... but i really have no idea why the CRTs has this ratio, ideally, I think the first person who make Television should use the golden ratio... or 3:2 (normal 35mm film size)....
