Many people invented motion picture cameras over the years, so its hard to know which of them you’re thinking of. But both Lumiere and Edison, who are usually given priority for workable cameras, intended it for commercial purposes.You might be thinking of Eadweard J. Muybridge but he didn’t really invent a motion picture camera in the modern definition.
Viagra is used for certain kinds of pulmonary hypertension and in prevention of edema associated with altitude sickness. However, as stated before, it was originally tested for angina and failed that testing, but showed definite beneficial side effects in improving erectile capacity.
I came in to mention Q-tips, but it looks like bienville beat me to the punch.
Another one I can think of is the story of the technician working at a microwave transmitter site who noticed that the chocolate bar in his pocket melted when he was near the transmitter. Voila! Microwave oven!
I personally knew of a woman who was payed $4000 a week for about 16 weeks for off label use of REMICADE® - it worked researchers hoped it would. I don’t know if the new use was ever approved.
There’s an article in today’s Washington Post spelling out that something like 94% of Pfizer’s revenue from Neurontin came from off-label use; other such drugs are likewise noted. http://www.commondreams.org/headline/2010/03/21
Monistat Chafing Relief Powder Gel, a silicone-enhanced lotion intended to be used between the thighs to soothe the aforementioned chafing, is very popular for use by women as a makeup primer.
Primers, for anyone not up on this sorta thing, are used on faces to coat the skin prior to adding makeup, much like a paint primer, so there’s an even base and your face looks nice and smooth. “Official” primers cost $12 - $30, while the Monistat stuff runs about $8. Not all women use primers (I’d say most of us don’t), but for those who do, an increasing number swear by Monistat. Here’s a good comparison on a beauty blog, and an eHow article too.
Note: don’t mistakenly use the Monistat vaginal cream for this purpose! They are very very different!
As noted, the Slinky was originally developed for the navy in WWII, then adapted into a toy. Later in Vietnam, US soldiers would sling them over tree limbs for radio antennae
My vote is for the Hitachi Magic Wand “massager”-- one of the most popular vibrators of all time, but as far as I know Hitachi has never actually marketed it as a sex toy. They’ve sold zillions of them over the years and I doubt many of them actually get used on people’s backs.
It is taking every ounce of willpower to not google this! What a mean thing to do to me. Why must I be compelled to google things I should not?
I am sure that I would have thousands of examples if I wasn’t trying to think of them…but right now all that come to mind are pharmaceuticals. Does that still count even though it has been addressed?
Wellbutrin was meant as an anti-depressant but had the serendipitous side effect of reducing nicotine cravings, so also became Zyban as a quit-smoking aid.
Trileptol is an anti-seizure medication, which has mood stabilization effects, so it is often being used for that purpose.
Aspirin is a pain/fever reducer but has blood thinning properties, so now many people are on an aspirin regimen for this.
Motrin is an anti-inflammatory pain/fever reducer which can also slow bleeding, so many women take prescription strength Motrin on a schedule to treat heavy periods.
Mifepristone and misoprostol are (I believe) cancer medications, but they are being used to induce abortion (called medical abortion or the abortion pill).
Of course any belief that this actually reduces smell in a fridge is purely psychological. It can only kill acidic smells, and only the ones that come in contact with a fresh surface. Unless your circulating air through your baking soda, it’s pretty much just sitting their taking up space.
Vibram Fivefingers were released to yawns as “yachthing” footwear (no fucking clue why someone needed specialized footwear for that), but really exploded in popularity when the barefoot running community discovered them. They’re not nearly as big as some of the other things mentioned here, but they’re huge right now for a niche product.
Most carbonated beverages were sold as tonics (From the original tonic water, a carbonated water with added quinine against malaria, a mild version of which can still be found at supermarkets, ) but that’s not at all the same as patent medicines. Both Coke and 7Up were primarily refreshing drinks. Some advertising may have claimed other qualities for them, but neither started out really any differently from what they are today.
