How about stereo AM radio
The wire recorder.
It came before tape recorders and used a roll of fine wire to record audio. My Dad had one and still has dozens of rolls of unhearable sounds.
Fizzies.
We used to eat a couple of packs and then have belching contests. They’ve disappeared.
The scent disc
Looked like a little CD player that played “smells” like roses or chocolate.
Tennhippie: I don’t buy it. The fact is, the people who want it banned have political clout, and the people who’s lives are saved don’t.
Let me ask you: If a compound came along that miraculously cured cancer and heart disease, and saved millions of Americans a year, do you think we’d ban it because there was some evidence that it caused eggshell thinning in birds?
DDT is but one example of the western green movement’s disregard for the lives and comfort of other people in the 3rd world, and of poor people in our own countries.
Personal jet packs (Cecil did that one)
3D Movies
Me163 Komet (History’s only rocket powered combat aircraft. A literal dead-end technology for a lot of German pilots.)
Cryogenics
Heroin as a cure for Opium addiction
Nanotechnology (might catch on in the next century though)
Neural nets
Smokeless cigarettes
New style education
The League of Nations
Mike King: The ME163 Komet was the first rocket powered combat aircraft, and the only one “used in anger” but it was not “history’s only” one. The Brits created the Saunders-Roe SR.53 rocket fighter (although admittedly it had a tiny jet engine so they poor pilot didn’t have to glide back to base as the Komet pilot did).
But I digress…

Just a Q:
Does anyone have any more information about this?
Thanks.
Doctordec:
I may be mistaken, but I believe the wire recorder was a precursor to the tape recorder. It established a new line of technology, and as that line advanced it was replaced by improved designs. Thus, I wouldn’t call it a “failure” per se, but rather “obsolete,” like the Model T, the rotary dial, or the Apple computer (troll alert! troll alert! 
As for the marketplace killing invention, we were just talking about Beta-format video the other day. The picture quality was allegedly better (though personally I could never tell the difference), but the tapes weren’t long enough to record movies, which is what most people wanted in those days. (Still do.)
And if I can add my suggestion to the list:
professional team tennis
Polaroid instant movie film (1978). Made obsolete by video as soon as it was introduced, and the picture quality was crappy.
Household robots.
From Doctordec: The wire recorder. It came before tape recorders and used a roll of fine wire to record audio. My Dad had one and still has dozens of rolls of unhearable sounds.
The wire recorder is actually another 19th century invention, generally credited to Valdemar Poulsen of Denmark in 1898, although there had been earlier work by others. See http://www.rci.rutgers.edu/~dmorton/mrchrono.html for more details.
Also, the topic of old wire recording recoverability comes up every so often on rec.antiques.radio+phono, and the general concensus is that they usually can be played. See: [Life of signal on wire recording?](http://x26.deja.com/viewthread.xp?AN=499965239&search=thread&svcclass=dnyr&ST=PS&recnum=<spr.bogus-1107992006470001@pool0308.cvx19-bradley.dialup.earthlink.net>%231/1&gro up=rec.antiques.radio%2bphono&frpage=getdoc.xp) for more details.
Fizzies are not dead!
They were discontinued because of the sacharine scare, but now they are back with nutrasweet!

(My vote for most annoying web site!)
I just bought some from Ralphs, a local supermarket, not too long ago.
Did anyone mention:
Delorean automobile,
Edsel,
and was it the chevy chevette? I am not sure (I know it was made by chevrolet,) that had the motor in the back with all the (sp)louvers in the trunk?
GMC Pacer, yeech I was almost run over on the freeway after renting one…it could not get up the on ramp fast enough to join on going traffic
KissThis
I think you meant Chevy Corvair and AMC Pacer.
A point in every direction is like no point at all
Right you are oblio and thanks!
Mekphito, here you go with the ice aircraft carrier thing. http://www.skypoint.com/~jbp/furashita/habbak_f.htm
Sorry I left that out.
Oh, dear. I misspelled your name and failed to mention that the latter half of the page I cite is fanciful tripe. This critter was never actually built.
No problemo, King, thanks for the info.
That reminds me of the concrete ship in the Delaware Bay. We used to see it when we’d go down the shore when I was a kid. Here’s a link, if interested, but not much information on it:

dhanson: What part don’t you “buy”? That it is unnecessarily dangerous? That there are better chemicals available?
The fact is, the makers of this stuff are using their political clout to say, in effect: “Okay, we won’t sell it in this country. But surely it’s okay to dump it on the poor brown people.” I’m surprised you go along with that sort of attitude. Incidentally, DDT is not the only way to fight malaria.

Wait, no it isn’t.
