Major electronics brands have announced plans for 3D TV, including Panasonic, Samsung and Sony. Some have already launched new 3D TV sets. They hope to capitalize on the huge 3D theatrical success of James Cameron's Avatar.

The technology retail giant Best Buy said its Full HD 3D Home Theater System will be available at Best Buy stores' Magnolia Home Theater division for $2899.99. The system comprises a 50-inch Panasonic VIERA television for $2,499.95, with a pair of 3D glasses, and a Blu-ray disc player for $399.95. Extra glasses will cost $149.95 each.

Best Buy intends to establish and maintain leadership in the new television technology. That's one way it differentiates from Wal-Mart and other competitors. Younger consumers express great interest in 3-D TV, although the popularity of 3D technology is just beginning. Television successfully moving from black and white, to color, to high-definition, now reached the final frontier delivering immersive, totally realistic 3D imagery. Among the problems are limited 3D content on TV channels and the hefty price tags for the 3D TVs. Some experts believe that these factors may slow down sales.
