With the awareness of global warming and energy saving appliances available companies like GE have recently made plans to end the development of incandescent bulbs. Also because of this they can now focus more on the production of Organic bulbs which save energy and actually last longer. I believe the real reason for the switch is because Australia, Canada and many US states are planning to ban the companies with bans starting in 2012 so that’s a nice little motivational push for GE.
