Panasonic's 50-inch 3-D plasma television went on sale March 10 for just under $3,000. It sold out in its first week.
Panasonic is now taking back orders. Rival Samsung's larger 55-inch 3-D TV went on sale Sunday for $3,200.
TV makers are hoping the popularity of the 3D movie Avatar will continue to drive 3-D television sales despite the high price tag.
