Remember that laserdisc didn't die either. But it didn't supplant VHS. It just became a videophile niche format. Even after DVD came out, plenty of places still carried laserdisc.

Part of that was that LD was only a "play" format. VHS was "play" and "record". The average public wants convenience first, quality second, so LD stayed on the fringes.

DVD didn't start to replace VHS until DVD recorders became cheaper. Likewise, when BD players come down and BD recorders go desktop, then DVD will start to be phased out.
