If all light bulbs lasted 117 years wouldn't all the light bulbs manufacturers be out of business :-)?

That's certainly been conventional business strategy theory, actually the answer is that you diversify into other areas based on your excellent reputation as a long life light bulb manufacturer. Which given that you need to constantly change as a manufacturer anyway is not as scary as it sounds - light bulb manufacturers that only manufacture short life span incandescent bulbs are also about to find themselves out of business anyway.


And continually using more finite resources to manufacture new products just to stay "in business" will eventually end up with all of us going "out of business"...
