Question, why did DVD succeed when earlier RCA CED and Laserdisc bombed?

LV disks were the best media for fidelity and included stereo first. Granted there were flaws with "laser rot" but after the bugs were worked out the format was the best there was until digital came out. There would be no CD or DVD disks without the work done on LV. Yes, I still have a player and there are four total players including digital VHS, DVD, HD DVD and multiple format Blu ray here in the house!
